Accounting Policies [Abstract]
Summary of Significant Accounting Policies	1. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES Reporting Entity and Segments HealthStream, Inc. (the “Company”) was incorporated in 1990 as a Tennessee corporation and is headquartered in Nashville, Tennessee. The Company operates in three segments: HealthStream Workforce Solutions, HealthStream Patient Experience Solutions, and HealthStream Provider Solutions. Workforce Solutions products consist of SaaS-based services and subscription-based solutions to meet the ongoing training, certification, assessment and development needs of the healthcare community. These solutions provide, deliver and track computer based education for our customers in the United States through our software-as-a-service (SaaS) model. Patient Experience products offer healthcare organizations a wide range of quality and satisfaction surveys, consulting services, analyses of survey results, and other research-based services. Provider Solutions products offer healthcare organizations software applications for administering and tracking provider credentialing, privileging, call center and enrollment. Recently Adopted Accounting Standards The Company adopted Accounting Standards Update (“ASU”) 2015-16, Business Combinations (Topic 805) Recognition of Revenue Revenues are derived from providing services through our SaaS-based workforce development platform products, courseware subscriptions, provision of survey and research services, sales of software licensing arrangements, software maintenance and support, professional services, custom courseware development and other education and training services. The Company recognizes revenue when it is realized or realizable and earned. The Company considers revenue realized or realizable and earned when persuasive evidence of an arrangement exists, prices are fixed or determinable, services and products are provided to the customer and collectability is probable or reasonably assured. Revenue recognized from software and other arrangements is allocated to each element of the arrangement based on the relative fair values of the elements. While elements include software products and post contract customer support, the fair value of each element is based on vendor specific objective evidence (VSOE). For installed software products, if fair value cannot be determined for each undelivered element of the arrangement, all revenue from the arrangement is deferred until fair value can be determined or until all elements of the arrangement are delivered and customer acceptance has occurred. Sales of the Company’s SaaS-based workforce development platform products include customer support, implementation services, and training; therefore all revenues are deferred until the SaaS-based product is implemented, at which time revenues are recognized ratably over the subscription service period. In the event that circumstances occur, which give rise to uncertainty regarding the collectibility of contracted amounts, revenue recognition is suspended until such uncertainty is resolved. Fees for these services are billed on either a monthly, quarterly, or annual basis. Revenues derived from the delivery of services through the Company’s SaaS-based workforce development platform products and courseware subscriptions are recognized ratably over the term of the subscription service agreement or over the historical usage period, if usage typically differs from the subscription period. Other training revenues are generally recognized upon the completion of training. Revenues derived from the license of installed software products are recognized using the residual method upon delivery of the software, when VSOE of fair value for the undelivered elements within the contract can be established. If the Company cannot objectively determine the fair value of each undelivered element based on the VSOE of fair value, the Company defers revenue recognition until all elements are delivered, all services have been performed, or until fair value can be objectively determined. Software support and maintenance revenues are recognized ratably over the term of the related agreement. Revenues recognized from the Company’s survey and research services are determined using both the proportional performance method and the completed contract method. Revenues are generally earned over the estimated survey cycle, which typically ranges from less than one month to up to five months. The survey cycle is generally initiated based on the receipt of the first survey response and runs through provision of related survey reports to the customer. If survey results are not available to the customer during the survey fielding cycle, revenues are recognized at time of report delivery. Revenues for coaching and consulting engagements are recognized using the proportional performance method over the term of the underlying contract. Fees for survey services are billed upon initiation of the survey cycle, with progress billings made throughout the survey cycle. Fees for coaching and consulting engagements are billed upon initiation of the engagement with progress billings throughout the term of the contract. Revenues from professional services and courseware development services are recognized upon the completion of performance milestones and deliverables using the proportional performance method. All other revenues are recognized as the related services are performed or products are delivered. Fees for these services are generally billed at project initiation and upon completion of various milestones. Principles of Consolidation The consolidated financial statements include the accounts of the Company and its subsidiaries, all of which are wholly-owned. inter-company Use of Estimates The consolidated financial statements are prepared in accordance with U.S. generally accepted accounting principles. These accounting principles require management to make estimates and assumptions that affect the amounts reported in the financial statements and accompanying notes. Actual results could differ from those estimates and such differences could be material to the consolidated financial statements. Cash Equivalents The Company considers cash equivalents to be unrestricted, highly liquid investments with initial maturities of less than three months. Marketable Securities Marketable securities are classified as available for sale and are stated at fair market value, with the unrealized gains and losses, net of tax, reported in other comprehensive income (loss) on the accompanying consolidated balance sheets. Realized gains and losses and declines in market value judged to be other than temporary on investments in marketable securities are included in interest and other income on the accompanying consolidated statements of income. The cost of securities sold is based on the specific identification method. Interest and dividends on securities classified as available for sale are included in other income (expense) on the accompanying consolidated statements of income. Premiums and discounts are amortized over the life of the related available for sale security as an adjustment to yield using the effective interest method. Accounts Receivable-Unbilled Accounts receivable-unbilled Deferred Revenue Deferred revenue represents amounts that have been billed or collected in advance of revenue recognition. The Company typically invoices customers in quarterly, bi-annual, or annual installments, and occasionally customers will pay for multi-year contracts in advance. Deferred revenue is reduced as the revenue recognition criteria are met. Prepaid Royalties Prepaid royalties represents advance payments associated with the sale of third party products, such as courseware subscriptions. Royalties are typically paid in advance at the commencement of the revenue cycle, or periodically throughout the revenue cycle, such as quarterly, bi-annual, or annual installments. Royalty payments are amortized over the term of the underlying contracts, which generally range from 12 to 36 months, in order to match the direct royalty costs to the same period the subscription revenue is recognized. Amortization of royalties is included under the caption “cost of revenues (excluding depreciation and amortization)” in the accompanying consolidated statements of income. Allowance for Doubtful Accounts The Company estimates its allowance for doubtful accounts using a specific identification method in which management considers the facts and circumstances surrounding each potentially uncollectible receivable. An allowance is also maintained for accounts that are not specifically identified that may become uncollectible in the future. Uncollectible receivables are written-off in the period management believes it has exhausted every opportunity to collect payment from the customer. Bad debt expense is recorded when events or circumstances indicate an additional allowance is required based on the Company’s specific identification approach. Changes in the allowance for doubtful accounts and the amounts charged to bad debt expense for the years ended December 31, were as follows (in thousands): Allowance Charged Write-offs Allowance 2016 $ 303 $ 640 $ (80 ) $ 863 2015 $ 331 $ 284 $ (312 ) $ 303 2014 $ 211 $ 237 $ (117 ) $ 331 Capitalized Software Development Capitalized software development is stated on the basis of cost, and is presented net of accumulated amortization. The Company capitalizes costs incurred during the software development phase for projects when such costs are material. These assets are amortized using the straight-line method, generally ranging between three to five years. The Company capitalized approximately $10.0 million and $7.3 million during 2016 and 2015, respectively. Amortization of capitalized software development was approximately $7.7 million and $6.2 million during 2016 and 2015, respectively. Maintenance and operating costs are expensed as incurred. As of December 31, 2016 and 2015, there were no capitalized software development costs for computer software developed for resale. Fair Value Measurements Fair value is defined as the price that would be received to sell an asset or paid to transfer a liability in the principal or most advantageous market in an orderly transaction between market participants at the measurement date. The fair value hierarchy prioritizes the inputs to valuation techniques used in measuring fair value. There are three levels to the fair value hierarchy based on the reliability of inputs, as follows: Level 1 Observable inputs that reflect quoted prices (unadjusted) for identical assets or liabilities in active markets. Level 2 Inputs other than quoted prices included in Level 1 that are observable for the asset or liability, either directly or indirectly. Level 3 Unobservable inputs in which little or no market data exists, therefore requiring the Company to develop its own assumptions. The Company evaluates assets and liabilities subject to fair value measurements on a recurring basis to determine the appropriate level at which to classify them for each reporting period. This determination requires significant judgments to be made by the Company. At December 31, 2016 and 2015, our assets measured at fair value on a recurring basis consisted of marketable securities, which are classified as available for sale (see Note 4 – Marketable Securities). The Company did not have any financial liabilities that were subject to fair value measurements as of such dates. Property and Equipment Property and equipment are stated on the basis of cost. Depreciation and amortization are provided on the straight-line Years Furniture and fixtures 5-10 Equipment 3-5 Goodwill and Intangible Assets Goodwill represents the excess of purchase price in a business combination over the fair value of the net identifiable assets acquired. The carrying amount of our goodwill is evaluated for impairment at least annually during the fourth quarter and whenever events or changes in facts or circumstances indicate that impairment may exist. In accordance with ASC 350, Intangibles – Goodwill and Other As of December 31, 2016, intangible assets with remaining unamortized balances include contract rights and customer relationships, internally-developed technology and patents, non-competition agreements, and trade names. These intangible assets are considered to have definite useful lives and are being amortized on a straight line basis over periods typically ranging between three and fifteen years. The weighted average amortization period for definite lived intangible assets as of December 31, 2016 was 11.1 years. Intangible assets are reviewed for impairment whenever events or changes in facts or circumstances indicate that the carrying amount of the assets may not be recoverable. There were no impairments identified or recorded for the years ended December 31, 2016, 2015, or 2014. Long-Lived Long-lived assets to be held for use are reviewed for events or changes in facts and circumstances, both internally and externally, which may indicate that an impairment of long-lived long-lived Non-Marketable Equity Investments Non-marketable equity investments are accounted for using the equity method when the Company can exercise significant influence over the investee. Investments for which the Company is not able to exercise significant influence over the investee are accounted for under the cost method. The proportionate share of income or loss from equity method investments are recorded under the caption “other income, net” in the accompanying consolidated statements of income. Financial Instruments The Company has various financial instruments, including cash and cash equivalents, accounts receivable, accounts receivable-unbilled, accounts payable, accrued liabilities, and deferred revenue. The carrying amounts of these financial instruments approximate fair value because of the short term maturity or short term nature of such instruments. The Company also has marketable securities, which are recorded at approximate fair value based on quoted market prices or alternative pricing sources (see Note 4 – Marketable Securities). Advertising The Company expenses the costs of advertising as incurred. Advertising expense for the years ended December 31, 2016, 2015, and 2014 was approximately $1.0 million, $1.1 million, and $0.7 million, respectively. Shipping and Handling Costs Shipping and handling costs that are associated with our products and services are included in cost of revenues. Income Taxes Income taxes are accounted for using the asset and liability method, whereby deferred tax assets and liabilities are determined based on the temporary differences between the financial statement and tax bases of assets and liabilities measured at tax rates that will be in effect for the year in which the differences are expected to affect taxable income. Management evaluates all available evidence, both positive and negative, to determine whether, based on the weight of that evidence, a valuation allowance is needed. Future realization of the tax benefit of an existing deductible temporary difference or carryforward ultimately depends on the existence of sufficient taxable income of the appropriate character within the carryback or carryforward period available under the tax law. There are four possible sources of taxable income that may be available under the tax law to realize a tax benefit for deductible temporary differences and carryforwards: 1) future reversals of existing taxable temporary differences, 2) future taxable income exclusive of reversing temporary differences and carryforwards, 3) taxable income in prior carryback year(s) if carryback is permitted under the tax law, and 4) tax-planning strategies that would, if necessary, be implemented to realize deductible temporary differences or carryforwards prior to their expiration. Management reviews the realizability of its deferred tax assets each reporting period to identify whether any significant changes in circumstances or assumptions have occurred that could materially affect the realizability of deferred tax assets. As of December 31, 2016, the Company had established a valuation allowance of $654,000 for the portion of its net deferred tax assets that are not more likely than not expected to be realized. The Company accounts for income tax uncertainties using a more-likely-than-not recognition threshold based on the technical merits of the tax position taken. Tax positions that meet the more-likely-than-not recognition threshold are measured in order to determine the tax benefit to be recognized in the financial statements. The Company expenses any penalties or interest associated with tax obligations as general and administrative expenses and interest expense, respectively. Earnings Per Share Basic earnings per share is computed by dividing the net income available to common shareholders for the period by the weighted average number of common shares outstanding during the period. Diluted earnings per share is computed by dividing the net income for the period by the weighted average number of common and common equivalent shares outstanding during the period. Common equivalent shares are composed of incremental common shares issuable upon the exercise of stock options and restricted share units subject to vesting. The dilutive effect of common equivalent shares is included in diluted earnings per share by application of the treasury stock method. Common equivalent shares that have an anti-dilutive effect on diluted net income per share have been excluded from the calculation of diluted weighted average shares outstanding for the years ended December 31, 2016, 2015, and 2014. Concentrations of Credit Risk and Significant Customers The Company’s credit risks relate primarily to cash and cash equivalents, marketable securities and accounts receivable. The Company places its temporary excess cash investments in high quality, short-term The Company sells its products and services to various companies in the healthcare industry that are located in the United States. We perform ongoing credit evaluations of our customers’ financial condition and generally require no collateral from customers. An allowance for doubtful accounts is maintained for potentially uncollectible accounts receivable. The Company did not have any single customer representing over 10% of net revenues or accounts receivable during 2016, 2015, or 2014. Stock Based Compensation As of December 31, 2016, the Company maintains three stock based compensation plans under which awards are outstanding, which are described in Note 11. The Company accounts for stock based compensation using the fair-value based method for costs related to share-based payments, including stock options and restricted share units. The Company uses the Black Scholes option pricing model for calculating the fair value of option awards issued under its stock based compensation plan. The Company measures compensation cost of restricted share units based on the closing fair market value of the Company’s stock on the date of grant. Stock based compensation cost is measured at the grant date, based on the fair value of the award that is ultimately expected to vest, and is recognized as an expense over the requisite service period. The Company recognizes tax benefits from stock based compensation if an excess tax benefit is realized. Excess tax benefits are recorded as an increase to common stock when realized.

Business Combinations	5. BUSINESS COMBINATIONS Morrisey Associates, Inc. On August 8, 2016, Echo, Inc. (“Echo”), a wholly owned subsidiary of the Company, acquired all of the outstanding stock of Morrisey Associates, Inc. (“MAI”), a Chicago, Illinois based company that provides credentialing and privileging software to healthcare organizations. The acquisition of MAI allows the Company to expand its credentialing and privileging product offerings and solutions to healthcare organizations. The consideration paid for MAI consisted of approximately $48.0 million in cash, which the Company funded with cash on hand, and was not subject to any post-closing working capital or similar adjustment. The Company incurred approximately $953,000 in transaction costs, all of which were incurred during the year ended December 31, 2016. The transaction costs were recorded in other general and administrative expenses in the consolidated statements of income. The results of operations for MAI have been included in the Company’s consolidated financial statements from the date of acquisition, and are also included in the HealthStream Provider Solutions segment. A summary of the purchase price is as follows (in thousands): Cash paid at closing $ 44,120 Cash held in escrow 3,880 Total consideration paid $ 48,000 The following table summarizes the fair value of the assets acquired and liabilities assumed as of the date of acquisition (in thousands): Accounts receivable, net 3,402 Prepaid royalties and other prepaid assets 187 Property and equipment 75 Deferred tax assets 1,507 Goodwill 20,467 Intangible assets 27,400 Accounts payable and accrued liabilities (1,031 ) Deferred revenue (4,007 ) Net assets acquired $ 48,000 The excess purchase price over the fair values of net tangible and intangible assets has been recorded as goodwill. The fair values of tangible and identifiable intangible assets and deferred revenue are based on management’s estimates and assumptions. The fair values of assets acquired and liabilities assumed are based on based on management’s estimates and assumptions. The goodwill balance is primarily attributed to the assembled workforce, additional market opportunities from offering MAI’s products, and expected synergies from integrating MAI with other products or other combined functional areas within the Company. The goodwill balance is deductible for U.S. income tax purposes. The net tangible assets include deferred revenue, which was adjusted down from a book value at the acquisition date of $8.8 million to an estimated fair value of $4.0 million. The $4.8 million write-down of deferred revenue will result in lower revenues than would have otherwise been recognized for such services. The following table sets forth the components of identifiable intangible assets and their estimated useful lives as of the acquisition date (in thousands): Fair Useful life Customer relationships $ 21,400 13 years Developed technology 5,400 5 years Trade name 600 6 years Total intangible assets subject to amortization $ 27,400 The amounts of revenue and operating loss of MAI included in the Company’s consolidated statement of income from the date of acquisition of August 8, 2016 to the period ending December 31, 2016 are as follows (in thousands): Total revenues $ 2,581 Operating loss $ (2,358 ) The following unaudited pro forma financial information summarizes the combined results of operations of the Company and MAI, which was significant for purposes of the unaudited pro forma financial information disclosure, as though the companies were combined as of January 1, 2015 (in thousands, except per share data): Year Ended December 31, 2016 2015 Total revenues $ 236,205 $ 218,042 Net income $ 6,610 $ 7,533 Basic earnings per share $ 0.21 $ 0.25 Diluted earnings per share $ 0.21 $ 0.25 These unaudited pro forma combined results of operations include certain adjustments arising from the acquisition such as adjustment for amortization of intangible assets, depreciation of property and equipment, and fair value adjustments of acquired deferred revenue balances. The unaudited pro forma combined results of operations is for informational purposes only and is not indicative of what the Company’s results of operations would have been had the transaction occurred at the beginning of the period presented or to project the Company’s results of operations in any future period. The unaudited pro forma financial information for the years ended December 31, 2016 and 2015 combines the historical results of the Company and MAI for the years ended December 31, 2016 and 2015 and the pro forma adjustments listed above. HealthLine Systems On March 16, 2015, the Company acquired all of the membership interests of HealthLine Systems, LLC (“HLS”), a San Diego, California based company that specializes in credentialing, privileging, call center, and quality management solutions for the healthcare industry. The acquisition of HLS enabled the Company to provide a comprehensive solution set for healthcare provider credentialing, privileging, enrollment, referral, onboarding, and analytics in support of HealthStream’s approach to talent management for healthcare organizations. The consideration paid for HLS consisted of approximately $90.5 million in cash (taking into account an estimated closing working capital adjustment and the payment of an incremental tax indemnification claim by the Company as noted below). The Company incurred approximately $1.3 million in transaction costs associated with the acquisition, of which $965,000 were incurred during the year ended December 31, 2015 and $329,000 were incurred during the year ended December 31, 2014. The transaction costs were recorded in other general and administrative expenses in the consolidated statements of income for such periods. The results of operations for HLS have been included in the Company’s consolidated financial statements from the date of acquisition, and are also included in the HealthStream Provider Solutions segment. A summary of the purchase price is as follows (in thousands): Cash paid $ 89,850 Cash held in escrow 679 Total consideration paid $ 90,529 The following table summarizes the fair value of the assets acquired and liabilities assumed as of the date of acquisition (in thousands): Cash $ 54 Accounts receivable, net 3,052 Prepaid assets 546 Property and equipment 200 Deferred tax assets 2,523 Goodwill 43,798 Intangible assets 47,200 Accounts payable and accrued liabilities (1,085 ) Deferred revenue (5,979 ) Net assets acquired $ 90,309 The total consideration paid does not equal the fair value of assets acquired and liabilities assumed due to the post measurement period adjustment discussed below. The excess of purchase price over the fair values of net tangible and intangible assets has been recorded as goodwill. The fair values of tangible and identifiable intangible assets, deferred tax assets, deferred revenue, and other liabilities are based on management’s estimates and assumptions. Included in the assets and liabilities assumed is an estimated indemnification asset of $300,000 and a contingent liability of $700,000, both of which are associated with tax liabilities. The contingent liability is measured based on management’s estimate of a range of probable outcomes. The goodwill balance is primarily attributed to the assembled workforce, additional market opportunities from offering HLS’s products, and expected synergies from integrating HLS with other products or other combined functional areas within the Company. During the three months ended March 31, 2016, the Company received notice of an indemnification claim from the former owners of HLS pursuant to the terms of the membership interest purchase agreement. The terms of such agreement require the Company to indemnify such owners for incremental taxes incurred as the result of the structure of the acquisition, which had favorable tax aspects to the Company. The Company recorded a measurement period adjustment in relation to the claim that increased goodwill by approximately $2.2 million during the three months ended March 31, 2016. The additional goodwill is deductible for U.S. income tax purposes. The goodwill balance excluding such measurement period adjustment is also deductible for U.S. income tax purposes. During the three months ended September 30, 2016, the Company agreed to settle this indemnification claim for approximately $2.4 million in respect of such tax indemnification provision in the membership interest purchase agreement, a difference of approximately $200,000 from the $2.2 million measurement period adjustment. The Company surpassed the one year measurement period as of the period ended March 31, 2016; accordingly, in accordance with requisite accounting guidance, the $200,000 difference has been reflected as a charge against net income for the year ended December 31, 2016. The net tangible assets include deferred revenue, which was adjusted down from a book value at the acquisition date of $15.0 million to an estimated fair value of $6.0 million. The $9.0 million write-down of deferred revenue will result in lower revenues than would have otherwise been recognized for such services. The following table sets forth the components of identifiable intangible assets and their estimated useful lives as of the acquisition date (in thousands): Fair Useful life Customer relationships $ 42,600 13 years Developed technology 3,700 5 years Trade names 900 6 years Total intangible assets subject to amortization $ 47,200 The amounts of revenue and operating income (loss) of HLS included in the Company’s consolidated statement of income from the date of acquisition of March 16, 2015 to the period ending December 31, 2015 are as follows (in thousands): Total revenues $ 8,543 Operating loss $ (2,541 ) The following unaudited pro forma financial information summarizes the combined results of operations of the Company and HLS, which was significant for purposes of the unaudited pro forma financial information disclosure, as though the companies were combined as of January 1, 2015 (in thousands, except per share data): Year Ended December 31, 2016 2015 Total revenues $ 227,834 $ 219,108 Net income $ 4,924 $ 13,551 Basic earnings per share $ 0.16 $ 0.45 Diluted earnings per share $ 0.15 $ 0.44 These unaudited pro forma combined results of operations include certain adjustments arising from the acquisition such as adjustment for amortization of intangible assets, depreciation of property and equipment, fair value adjustments of acquired deferred revenue balances, and interest expense associated with borrowings under a revolving credit facility by the Company to partially fund the acquisition. The unaudited pro forma combined results of operations is for informational purposes only and is not indicative of what the Company’s results of operations would have been had the transaction occurred at the beginning of the period presented or to project the Company’s results of operations in any future period. The unaudited pro forma financial information for the years ended December 31, 2016 and 2015 combines the historical results of the Company and HLS for the years ended December 31, 2016 and 2015 and the pro forma adjustments listed above. Health Care Compliance Strategies On March 3, 2014, the Company acquired all of the stock of Health Care Compliance Strategies, Inc. (HCCS), a Jericho, New York based company that specializes in healthcare compliance solutions and services. The Company acquired HCCS to further advance its suite of workforce development solutions, including its offering of compliance solutions. The consideration paid for HCCS consisted of approximately $12.8 million in cash (taking into account a post-closing working capital adjustment) and 81,614 shares of our common stock. The Company made an additional payment of $750,000 during the second quarter of 2015, upon the achievement of certain performance milestones within one year post-closing. The Company incurred approximately $515,000 in transaction costs associated with the acquisition, of which $365,000 were incurred during the year ended December 31, 2014 and $150,000 were incurred during the year ended December 31, 2013. The transaction costs were recorded under the caption “other general and administrative” in the consolidated statements of income. In allocating the purchase price, the Company recorded approximately $6.2 million of goodwill, $8.4 million of identifiable intangible assets, $2.6 million of tangible assets, $625,000 of deferred tax assets, and $2.7 million of liabilities. Included in the recorded liabilities was an accrual for contingent consideration of approximately $600,000. The goodwill balance is primarily attributed to assembled workforce, additional market opportunities of HCCS’s compliance solutions, and expected synergies from integrating HCCS’s products into our platform. The goodwill balance is deductible for U.S. income tax purposes. The net tangible assets include deferred revenue, which was adjusted down from a book value at the acquisition date of $3.2 million to an estimated fair value of $1.7 million. The $1.5 million write-down of deferred revenue resulted in lower revenues than would have otherwise been recognized for such services. The results of operations for HCCS have been included in the Company’s consolidated financial statements from the date of acquisition, and are also included in the HealthStream Workforce Development Solutions segment. Other Business Combinations On June 30, 2016, the Company acquired all of the stock of Performance Management Services, Inc. (“PMSI”), a Company based in Tustin, California focused on competency-based performance development for nurses, for $4.0 million in cash and up to an additional $500,000 of contingent consideration. The acquisition, including associated transaction costs, is not considered material to the Company’s financial statements. The Company accounted for the acquisition as a business combination and has allocated the purchase consideration based on management’s estimates of fair value. The results of operations for PMSI are included in the Company’s consolidated financial statements from the date of acquisition and are included in the HealthStream Workforce Solutions segment. On July 25, 2016, the Company purchased all of the outstanding stock of Nursing Registry Consultants Corporation (“Nurse Competency”) not previously held by the Company for approximately $1.0 million in cash and up to an additional $75,000 in contingent consideration. Nurse Competency provides SaaS-based clinical assessment and testing products to the healthcare industry. The Company previously held a 32% minority equity interest in Nurse Competency and had accounted for such interest as an equity method investment. The fair value of the minority equity interest as of the July 25, 2016 acquisition date was approximately $484,000 and was determined in accordance with the fair value of the controlling interest acquired with consideration given to acquisition premiums, where applicable. The Company recorded a gain of approximately $225,000 to account for the difference between the noted acquisition date fair value of the minority equity interest and the carrying value as of such date. The gain is included in other income (expense), net in the consolidated statement of income for the year ended December 31, 2016. The Company accounted for the acquisition as a business combination and has allocated the purchase consideration based on management’s estimates of fair value. The results of operations for Nurse Competency are included in the Company’s consolidated financial statements from the date of acquisition and are included in the HealthStream Workforce Solutions segment.

The vesting period of the options and RSUs granted has historically ranged from immediate vesting to annual vesting up to four years, generally beginning one year after the grant date. As of December 31, 2016, approximately 1.5 million shares of unissued common stock remained reserved for future stock incentive grants under the 2016 Plan. The Company issues new shares of common stock when options are exercised or when RSUs become vested. Stock Option Activity A summary of activity and various other information relative to stock options for the year ended December 31, 2016 is presented in the tables below (in thousands, except exercise price). Common Weighted- Aggregate Outstanding at beginning of period 520 $ 6.41 Granted — — Exercised (44 ) 3.33 Expired — — Forfeited — — Outstanding at end of period 476 $ 6.74 $ 8,716 Exercisable at end of period. 476 $ 6.74 $ 8,716 The aggregate intrinsic value for stock options in the table above represents the total difference between the Company’s closing stock price on December 30, 2016 (the last trading day of the year) of $25.05 per share and the option exercise price, multiplied by the number of in-the-money options as of December 31, 2016. The weighted average remaining contractual term of options outstanding at December 31, 2016 was 1.6 years. Options exercisable at December 31, 2016 have a weighted average remaining contractual term of 1.6 years. Other information relative to option activity during the three years ended December 31, 2016 is as follows (in thousands): 2016 2015 2014 Total grant date fair value of stock options vested $ — $ 232 $ 630 Total intrinsic value of stock options exercised $ 820 $ 1,662 $ 5,912 Cash proceeds from exercise of stock options $ 146 $ 328 $ 1,094 Restricted Share Unit Activity A summary of activity relative to RSUs for the year ended December 31, 2016 is as follows (in thousands, except weighted average grant date fair value): Number of Weighted- Aggregate Outstanding at beginning of period 218 $ 25.21 Granted 116 20.72 Vested (74 ) 24.54 Forfeited (7 ) 24.50 Outstanding at end of period 253 $ 23.36 $ 6,331 The aggregate fair value of RSU awards that vested in 2016 and 2015, as of the respective vesting dates, was approximately $1.5 million and $1.4 million, respectively. A portion of RSUs that vested in 2016 and 2015 were net-share settled such that the Company withheld shares with value equivalent to the employees’ minimum statutory obligation for the applicable income and other employment taxes, and remitted the cash to the appropriate taxing authorities. The total shares withheld for RSUs during 2016 and 2015 were 15,373 and 8,922, respectively, and were based on the value of the RSUs on their respective settlement dates as determined by the Company’s closing stock price. Total payments related to RSUs for the employees’ tax obligations to taxing authorities were approximately $316,000 in 2016 and $230,000 in 2015, and are reflected as a financing activity within the consolidated statements of cash flows. These net-share settlements had the effect of share repurchases by the Company as they reduced and retired the number of shares that would have otherwise been issued as a result of the vesting and did not represent an expense to the Company. Stock Based Compensation Total stock based compensation expense, which is recorded in our consolidated statements of income, recorded for the years ended December 31, is as follows (in thousands): Years Ended December 31, 2016 2015 2014 Cost of revenues (excluding depreciation and amortization) $ 144 $ 824 $ 86 Product development 178 569 201 Sales and marketing 239 547 224 Other general and administrative 1,407 1,340 1,114 Total stock based compensation expense $ 1,968 $ 3,280 $ 1,625 The Company amortizes the fair value of all stock based awards, net of estimated forfeitures, on a straight-line basis over the requisite service period, which generally is the vesting period. As of December 31, 2016, total unrecognized compensation expense related to non-vested stock options and RSUs was approximately $3.1 million, net of estimated forfeitures, with a weighted average expense recognition period remaining of 2.4 years. The Company realized approximately $217,000 of excess tax benefits related to stock based awards during the year ended December 31, 2016, which was recorded as an increase to common stock. Stock based compensation cost for RSUs is measured based on the closing fair market value of the Company’s stock on the date of grant. Stock based compensation cost for stock options is estimated at the grant date based on the fair value calculated using the Black-Scholes Stock Awards During June 2015, the Company’s Chief Executive Officer (“CEO”), Robert A. Frist, Jr., entered into an agreement with the Company pursuant to which he contributed 54,241 of his personally owned shares of HealthStream, Inc. common stock to the Company, without any consideration paid to him. In connection with this contribution, the Company approved the grant of 49,310 shares of HealthStream, Inc. common stock to over 600 employees who were not otherwise eligible to receive equity awards and had at least one year of service with the Company. The Company recognized approximately $1.5 million of stock based compensation expense for these stock awards during the three months ended June 30, 2015 based on the closing fair market value of the Company’s stock on the date of the Company’s approval of these grants. In connection with these equity awards, effective in the second quarter of 2015, the Company withheld shares with value equivalent to the employees’ minimum statutory obligation for the applicable income and other employment taxes, and remitted the cash to the appropriate taxing authorities. The total shares withheld were 17,279, and were based on the value of the stock awards on the date of the Company’s approval of these grants, as determined by the Company’s closing stock price on that date. Total payments related to the employees’ tax obligations to taxing authorities for these stock awards were approximately $526,000, and are reflected as a financing activity within the consolidated statements of cash flows for the year ended December 31, 2015. These share withholdings had the effect of share repurchases by the Company as they reduced and retired the number of shares otherwise issuable as a result of the stock awards and did not represent an expense to the Company.

Debt	13. DEBT At December 31, 2016 and 2015, the Company had no debt outstanding. Revolving Credit Facility The Company maintains a Loan Agreement (the “Revolving Credit Facility”) with SunTrust Bank (“SunTrust”) in the aggregate principal amount of $50.0 million, which matures on November 24, 2017. Under the Revolving Credit Facility, the Company may borrow up to $50.0 million, which includes a $5.0 million swing line subfacility and a $5.0 million letter of credit subfacility, as well as an accordion feature that allows the Company to increase the Revolving Credit Facility by a total of up to $25.0 million, subject to securing additional commitments from existing lenders or new lending institutions. The obligations under the Revolving Credit Facility are guaranteed by each of the Company’s subsidiaries. At the Company’s election, the borrowings under the Revolving Credit Facility bear interest at either (1) a rate per annum equal to the highest of SunTrust’s prime rate or 0.5% in excess of the Federal Funds Rate or 1.0% in excess of one-month LIBOR (the “Base Rate”), plus an applicable margin, or (2) the one, two, three, or six-month per annum LIBOR for deposits in the applicable currency (the “Eurocurrency Rate”), as selected by the Company, plus an applicable margin. The applicable margin for Eurocurrency Rate loans depends on the Company’s funded debt leverage ratio and varies from 1.50% to 2.00%. The applicable margin for Base Rate loans depends on the Company’s funded debt leverage ratio and varies from 0.50% to 1.50%. Commitment fees and letter of credit fees are also payable under the Revolving Credit Facility. Principal is payable in full at maturity on November 24, 2017, and there are no scheduled principal payments prior to maturity. The Company is required to pay a commitment fee ranging between 20 and 30 basis points per annum of the average daily unused portion of the Revolving Credit Facility, depending on the Company’s funded debt leverage ratio. The purpose of the Revolving Credit Facility is for general working capital needs, permitted acquisitions (as defined in the Loan Agreement), and for stock repurchase and/or redemption transactions that the Company may authorize. The Revolving Credit Facility contains certain covenants that, among other things, restrict additional indebtedness, liens and encumbrances, changes to the character of the Company’s business, acquisitions, asset dispositions, mergers and consolidations, sale or discount of receivables, creation or acquisitions of additional subsidiaries, and other matters customarily restricted in such agreements. In addition, the Revolving Credit Facility requires the Company to meet certain financial tests, including, without limitation: • a funded debt leverage ratio (consolidated debt/consolidated EBITDA) of not greater than 3.0 to 1.0; and • an interest coverage ratio (consolidated EBITDA/consolidated interest expense) of not less than 3.0 to 1.0. As of December 31, 2016, the Company was in material compliance with all covenants. There were no balances outstanding on the Revolving Credit Facility as of December 31, 2016 and there were no borrowings under the Revolving Credit Facility during the year ended December 31, 2016. During the three months ended March 31, 2015, the Company borrowed approximately $28.0 million under the Revolving Credit Facility. During the three months ended June 30, 2015, the Company repaid approximately $28.0 million of balances previously outstanding under the Revolving Credit Facility from proceeds received in the Company’s public offering of 3,869,750 shares which closed on May 28, 2015.

Accounting Policies [Abstract]
Reporting Entity and Segments	Reporting Entity and Segments HealthStream, Inc. (the “Company”) was incorporated in 1990 as a Tennessee corporation and is headquartered in Nashville, Tennessee. The Company operates in three segments: HealthStream Workforce Solutions, HealthStream Patient Experience Solutions, and HealthStream Provider Solutions. Workforce Solutions products consist of SaaS-based services and subscription-based solutions to meet the ongoing training, certification, assessment and development needs of the healthcare community. These solutions provide, deliver and track computer based education for our customers in the United States through our software-as-a-service (SaaS) model. Patient Experience products offer healthcare organizations a wide range of quality and satisfaction surveys, consulting services, analyses of survey results, and other research-based services. Provider Solutions products offer healthcare organizations software applications for administering and tracking provider credentialing, privileging, call center and enrollment.
Recently Adopted Accounting Standards	Recently Adopted Accounting Standards The Company adopted Accounting Standards Update (“ASU”) 2015-16, Business Combinations (Topic 805)
Recognition of Revenue	Recognition of Revenue Revenues are derived from providing services through our SaaS-based workforce development platform products, courseware subscriptions, provision of survey and research services, sales of software licensing arrangements, software maintenance and support, professional services, custom courseware development and other education and training services. The Company recognizes revenue when it is realized or realizable and earned. The Company considers revenue realized or realizable and earned when persuasive evidence of an arrangement exists, prices are fixed or determinable, services and products are provided to the customer and collectability is probable or reasonably assured. Revenue recognized from software and other arrangements is allocated to each element of the arrangement based on the relative fair values of the elements. While elements include software products and post contract customer support, the fair value of each element is based on vendor specific objective evidence (VSOE). For installed software products, if fair value cannot be determined for each undelivered element of the arrangement, all revenue from the arrangement is deferred until fair value can be determined or until all elements of the arrangement are delivered and customer acceptance has occurred. Sales of the Company’s SaaS-based workforce development platform products include customer support, implementation services, and training; therefore all revenues are deferred until the SaaS-based product is implemented, at which time revenues are recognized ratably over the subscription service period. In the event that circumstances occur, which give rise to uncertainty regarding the collectibility of contracted amounts, revenue recognition is suspended until such uncertainty is resolved. Fees for these services are billed on either a monthly, quarterly, or annual basis. Revenues derived from the delivery of services through the Company’s SaaS-based workforce development platform products and courseware subscriptions are recognized ratably over the term of the subscription service agreement or over the historical usage period, if usage typically differs from the subscription period. Other training revenues are generally recognized upon the completion of training. Revenues derived from the license of installed software products are recognized using the residual method upon delivery of the software, when VSOE of fair value for the undelivered elements within the contract can be established. If the Company cannot objectively determine the fair value of each undelivered element based on the VSOE of fair value, the Company defers revenue recognition until all elements are delivered, all services have been performed, or until fair value can be objectively determined. Software support and maintenance revenues are recognized ratably over the term of the related agreement. Revenues recognized from the Company’s survey and research services are determined using both the proportional performance method and the completed contract method. Revenues are generally earned over the estimated survey cycle, which typically ranges from less than one month to up to five months. The survey cycle is generally initiated based on the receipt of the first survey response and runs through provision of related survey reports to the customer. If survey results are not available to the customer during the survey fielding cycle, revenues are recognized at time of report delivery. Revenues for coaching and consulting engagements are recognized using the proportional performance method over the term of the underlying contract. Fees for survey services are billed upon initiation of the survey cycle, with progress billings made throughout the survey cycle. Fees for coaching and consulting engagements are billed upon initiation of the engagement with progress billings throughout the term of the contract. Revenues from professional services and courseware development services are recognized upon the completion of performance milestones and deliverables using the proportional performance method. All other revenues are recognized as the related services are performed or products are delivered. Fees for these services are generally billed at project initiation and upon completion of various milestones.
Principles of Consolidation	Principles of Consolidation The consolidated financial statements include the accounts of the Company and its subsidiaries, all of which are wholly-owned. inter-company
Use of Estimates	Use of Estimates The consolidated financial statements are prepared in accordance with U.S. generally accepted accounting principles. These accounting principles require management to make estimates and assumptions that affect the amounts reported in the financial statements and accompanying notes. Actual results could differ from those estimates and such differences could be material to the consolidated financial statements.
Cash Equivalents	Cash Equivalents The Company considers cash equivalents to be unrestricted, highly liquid investments with initial maturities of less than three months.
Marketable Securities	Marketable Securities Marketable securities are classified as available for sale and are stated at fair market value, with the unrealized gains and losses, net of tax, reported in other comprehensive income (loss) on the accompanying consolidated balance sheets. Realized gains and losses and declines in market value judged to be other than temporary on investments in marketable securities are included in interest and other income on the accompanying consolidated statements of income. The cost of securities sold is based on the specific identification method. Interest and dividends on securities classified as available for sale are included in other income (expense) on the accompanying consolidated statements of income. Premiums and discounts are amortized over the life of the related available for sale security as an adjustment to yield using the effective interest method.
Accounts Receivable-Unbilled	Accounts Receivable-Unbilled Accounts receivable-unbilled
Deferred Revenue	Deferred Revenue Deferred revenue represents amounts that have been billed or collected in advance of revenue recognition. The Company typically invoices customers in quarterly, bi-annual, or annual installments, and occasionally customers will pay for multi-year contracts in advance. Deferred revenue is reduced as the revenue recognition criteria are met.
Prepaid Royalties	Prepaid Royalties Prepaid royalties represents advance payments associated with the sale of third party products, such as courseware subscriptions. Royalties are typically paid in advance at the commencement of the revenue cycle, or periodically throughout the revenue cycle, such as quarterly, bi-annual, or annual installments. Royalty payments are amortized over the term of the underlying contracts, which generally range from 12 to 36 months, in order to match the direct royalty costs to the same period the subscription revenue is recognized. Amortization of royalties is included under the caption “cost of revenues (excluding depreciation and amortization)” in the accompanying consolidated statements of income. Allowance for Doubtful Accounts The Company estimates its allowance for doubtful accounts using a specific identification method in which management considers the facts and circumstances surrounding each potentially uncollectible receivable. An allowance is also maintained for accounts that are not specifically identified that may become uncollectible in the future. Uncollectible receivables are written-off in the period management believes it has exhausted every opportunity to collect payment from the customer. Bad debt expense is recorded when events or circumstances indicate an additional allowance is required based on the Company’s specific identification approach.
Capitalized Software Development	Capitalized Software Development Capitalized software development is stated on the basis of cost, and is presented net of accumulated amortization. The Company capitalizes costs incurred during the software development phase for projects when such costs are material. These assets are amortized using the straight-line method, generally ranging between three to five years. The Company capitalized approximately $10.0 million and $7.3 million during 2016 and 2015, respectively. Amortization of capitalized software development was approximately $7.7 million and $6.2 million during 2016 and 2015, respectively. Maintenance and operating costs are expensed as incurred. As of December 31, 2016 and 2015, there were no capitalized software development costs for computer software developed for resale.
Fair Value Measurements	Fair Value Measurements Fair value is defined as the price that would be received to sell an asset or paid to transfer a liability in the principal or most advantageous market in an orderly transaction between market participants at the measurement date. The fair value hierarchy prioritizes the inputs to valuation techniques used in measuring fair value. There are three levels to the fair value hierarchy based on the reliability of inputs, as follows: Level 1 Observable inputs that reflect quoted prices (unadjusted) for identical assets or liabilities in active markets. Level 2 Inputs other than quoted prices included in Level 1 that are observable for the asset or liability, either directly or indirectly. Level 3 Unobservable inputs in which little or no market data exists, therefore requiring the Company to develop its own assumptions. The Company evaluates assets and liabilities subject to fair value measurements on a recurring basis to determine the appropriate level at which to classify them for each reporting period. This determination requires significant judgments to be made by the Company. At December 31, 2016 and 2015, our assets measured at fair value on a recurring basis consisted of marketable securities, which are classified as available for sale (see Note 4 – Marketable Securities). The Company did not have any financial liabilities that were subject to fair value measurements as of such dates.
Property and Equipment	Property and Equipment Property and equipment are stated on the basis of cost. Depreciation and amortization are provided on the straight-line Years Furniture and fixtures 5-10 Equipment 3-5
Goodwill and Intangible Assets	Goodwill and Intangible Assets Goodwill represents the excess of purchase price in a business combination over the fair value of the net identifiable assets acquired. The carrying amount of our goodwill is evaluated for impairment at least annually during the fourth quarter and whenever events or changes in facts or circumstances indicate that impairment may exist. In accordance with ASC 350, Intangibles – Goodwill and Other As of December 31, 2016, intangible assets with remaining unamortized balances include contract rights and customer relationships, internally-developed technology and patents, non-competition agreements, and trade names. These intangible assets are considered to have definite useful lives and are being amortized on a straight line basis over periods typically ranging between three and fifteen years. The weighted average amortization period for definite lived intangible assets as of December 31, 2016 was 11.1 years. Intangible assets are reviewed for impairment whenever events or changes in facts or circumstances indicate that the carrying amount of the assets may not be recoverable. There were no impairments identified or recorded for the years ended December 31, 2016, 2015, or 2014.
Long-Lived Assets	Long-Lived Long-lived assets to be held for use are reviewed for events or changes in facts and circumstances, both internally and externally, which may indicate that an impairment of long-lived long-lived
Non-Marketable Equity Investments	Non-Marketable Equity Investments Non-marketable equity investments are accounted for using the equity method when the Company can exercise significant influence over the investee. Investments for which the Company is not able to exercise significant influence over the investee are accounted for under the cost method. The proportionate share of income or loss from equity method investments are recorded under the caption “other income, net” in the accompanying consolidated statements of income.
Financial Instruments	Financial Instruments The Company has various financial instruments, including cash and cash equivalents, accounts receivable, accounts receivable-unbilled, accounts payable, accrued liabilities, and deferred revenue. The carrying amounts of these financial instruments approximate fair value because of the short term maturity or short term nature of such instruments. The Company also has marketable securities, which are recorded at approximate fair value based on quoted market prices or alternative pricing sources (see Note 4 – Marketable Securities).
Advertising	Advertising The Company expenses the costs of advertising as incurred. Advertising expense for the years ended December 31, 2016, 2015, and 2014 was approximately $1.0 million, $1.1 million, and $0.7 million, respectively.
Shipping and Handling Costs	Shipping and Handling Costs Shipping and handling costs that are associated with our products and services are included in cost of revenues.
Income Taxes	Income Taxes Income taxes are accounted for using the asset and liability method, whereby deferred tax assets and liabilities are determined based on the temporary differences between the financial statement and tax bases of assets and liabilities measured at tax rates that will be in effect for the year in which the differences are expected to affect taxable income. Management evaluates all available evidence, both positive and negative, to determine whether, based on the weight of that evidence, a valuation allowance is needed. Future realization of the tax benefit of an existing deductible temporary difference or carryforward ultimately depends on the existence of sufficient taxable income of the appropriate character within the carryback or carryforward period available under the tax law. There are four possible sources of taxable income that may be available under the tax law to realize a tax benefit for deductible temporary differences and carryforwards: 1) future reversals of existing taxable temporary differences, 2) future taxable income exclusive of reversing temporary differences and carryforwards, 3) taxable income in prior carryback year(s) if carryback is permitted under the tax law, and 4) tax-planning strategies that would, if necessary, be implemented to realize deductible temporary differences or carryforwards prior to their expiration. Management reviews the realizability of its deferred tax assets each reporting period to identify whether any significant changes in circumstances or assumptions have occurred that could materially affect the realizability of deferred tax assets. As of December 31, 2016, the Company had established a valuation allowance of $654,000 for the portion of its net deferred tax assets that are not more likely than not expected to be realized. The Company accounts for income tax uncertainties using a more-likely-than-not recognition threshold based on the technical merits of the tax position taken. Tax positions that meet the more-likely-than-not recognition threshold are measured in order to determine the tax benefit to be recognized in the financial statements. The Company expenses any penalties or interest associated with tax obligations as general and administrative expenses and interest expense, respectively.
Earnings Per Share	Earnings Per Share Basic earnings per share is computed by dividing the net income available to common shareholders for the period by the weighted average number of common shares outstanding during the period. Diluted earnings per share is computed by dividing the net income for the period by the weighted average number of common and common equivalent shares outstanding during the period. Common equivalent shares are composed of incremental common shares issuable upon the exercise of stock options and restricted share units subject to vesting. The dilutive effect of common equivalent shares is included in diluted earnings per share by application of the treasury stock method. Common equivalent shares that have an anti-dilutive effect on diluted net income per share have been excluded from the calculation of diluted weighted average shares outstanding for the years ended December 31, 2016, 2015, and 2014.
Concentrations of Credit Risk and Significant Customers	Concentrations of Credit Risk and Significant Customers The Company’s credit risks relate primarily to cash and cash equivalents, marketable securities and accounts receivable. The Company places its temporary excess cash investments in high quality, short-term The Company sells its products and services to various companies in the healthcare industry that are located in the United States. We perform ongoing credit evaluations of our customers’ financial condition and generally require no collateral from customers. An allowance for doubtful accounts is maintained for potentially uncollectible accounts receivable. The Company did not have any single customer representing over 10% of net revenues or accounts receivable during 2016, 2015, or 2014.
Stock Based Compensation	Stock Based Compensation As of December 31, 2016, the Company maintains three stock based compensation plans under which awards are outstanding, which are described in Note 11. The Company accounts for stock based compensation using the fair-value based method for costs related to share-based payments, including stock options and restricted share units. The Company uses the Black Scholes option pricing model for calculating the fair value of option awards issued under its stock based compensation plan. The Company measures compensation cost of restricted share units based on the closing fair market value of the Company’s stock on the date of grant. Stock based compensation cost is measured at the grant date, based on the fair value of the award that is ultimately expected to vest, and is recognized as an expense over the requisite service period. The Company recognizes tax benefits from stock based compensation if an excess tax benefit is realized. Excess tax benefits are recorded as an increase to common stock when realized.
