Accounting Policies [Abstract]
Description of Business and Significant Accounting Policies	Note 1—Description of Business and Significant Accounting Policies Nature of Operations Healthcare Services Group, Inc. (the “Company”) provides management, administrative and operating expertise and services to the housekeeping, laundry, linen, facility maintenance and dietary service departments of the healthcare industry, including nursing homes, retirement complexes, rehabilitation centers and hospitals located throughout the United States. Although the Company does not directly participate in any government reimbursement programs, the Company’s clients receive government reimbursements related to Medicare and Medicaid. Therefore, they are directly affected by any legislation relating to Medicare and Medicaid reimbursement programs. The Company provides services primarily pursuant to full service agreements with its clients. In such agreements, the Company is responsible for the day-to-day management of employees located at the clients’ facilities. The Company also provides services on the basis of management-only agreements for a limited number of clients. The agreements with clients typically provide for renewable one year service terms, cancellable by either party upon 30 to 90 days ’ notice after an initial period of 60 to 120 days . The Company is organized into two reportable segments: housekeeping, laundry, linen and other services (“Housekeeping”), and dietary department services (“Dietary”). Housekeeping consists of managing the clients’ housekeeping departments, which are principally responsible for the cleaning, disinfecting and sanitizing of resident rooms and common areas of a client’s facility, as well as the laundering and processing of the bed linens, uniforms, resident personal clothing and other assorted linen items utilized at a client facility. Dietary consists of managing the clients’ dietary departments, which are principally responsible for food purchasing, meal preparation and dietitian professional services, which includes the development of menus that meet residents’ dietary needs. Unaudited Interim Financial Data The accompanying unaudited consolidated financial statements have been prepared in accordance with generally accepted accounting principles in the United States (“U.S. GAAP”) for interim financial information and the requirements of Form 10-Q and Article 10 of Regulation S-X. Accordingly, these consolidated financial statements do not include all of the information and footnotes necessary for a complete presentation of financial position, results of operations and cash flows. However, in the Company’s opinion, all adjustments which are of a normal recurring nature and are necessary for a fair presentation have been reflected in these consolidated financial statements. The balance sheet shown in this report as of December 31, 2018 has been derived from, and does not includ e all of , the disclosures contained in the financial statements for the year ended December 31, 2018. These financial statements should be read in conjunction with the financial statements and notes thereto included in the Company’s Annual Report on Form 10-K for the year ended December 31, 2018. The results of operations for the three months ended March 31, 2019 are not necessarily indicative of the results that may be expected for any future period. Use of Estimates in Financial Statements In preparing financial statements in conformity with U.S. GAAP, estimates and assumptions are made that affect the reported amounts of assets and liabilities, disclosures of contingent assets and liabilities, and the reported amounts of revenues and expenses. Actual results could differ from those estimates. Significant estimates are used in determining, but are not limited to, the Company’s allowance for doubtful accounts, accrued insurance claims, valuations, deferred taxes and reviews for potential impairment. The estimates are based upon various factors including current and historical trends, as well as other pertinent industry and regulatory authority information. Management regularly evaluates this information to determine if it is necessary to update the basis for its estimates and to adjust for known changes. Principles of Consolidation The accompanying consolidated financial statements include the accounts of Healthcare Services Group, Inc. and its wholly-owned subsidiaries. All significant intercompany transactions and balances have been eliminated in consolidation. Cash and Cash Equivalents Cash and cash equivalents are held in U.S. financial institutions or in custodial accounts with U.S. financial institutions. Cash equivalents are defined as short-term, highly liquid investments with a maturity of three months or less at time of purchase that are readily convertible into cash and have insignificant interest rate risk. Accounts and Notes Receivable Accounts and notes receivable consist of Housekeeping and Dietary segment receivables from contracts with customers. Accounts receivable initially are recorded at the transaction amount, and are recorded after the Company has an unconditional right to payment where only the passage of time is required before payment is received. Each reporting period, the Company evaluates the collectability of outstanding receivable balances and records an allowance for doubtful accounts representing an estimate of probable losses. Additions to the allowance for doubtful accounts are made by recording a charge to bad debt expense reported in costs of services provided. Notes receivable are initially recorded when accounts receivable are transferred into a promissory note. Notes receivable are recorded as an alternative to accounts receivable to memorialize an unqualified promise to pay a specific sum, typically with interest, in accordance with a defined payment schedule. Refer to Note 3—Accounts and Notes Receivable herein for further information. Inventories and Supplies Inventories and supplies include housekeeping, linen and laundry supplies, as well as food provisions and supplies. Non-linen inventories and supplies are stated at cost to approximate a first-in, first-out (FIFO) basis. Linen supplies are amortized on a straight-line basis over their estimated useful life of 24 months . Revenue Recognition The Company recognizes revenue from service agreements with customers when or as the promised goods and services are provided to customers. Revenues are reported net of sales taxes that are collected from customers and remitted to taxing authorities. The guidance under the Financial Accounting Standards Board ( " FASB " ) Accounting Standards Codification subtopic 606 Revenue from Contracts with Customers ( " ASC 606 " ) became effective and was adopted by the Company as of January 1, 2018 by applying the modified retrospective method for contracts that were not completed as of January 1, 2018. The standard requires the Company to recognize revenue as the promised goods and services within the terms of the Company’s contracts are performed and satisfied. The amount of revenue recognized by the Company is based on the consideration to which the Company expects to be entitled in exchange for providing the contracted goods and services. The adoption of this standard did not have a material impact on the Company's accounting for revenue earned relating to the Housekeeping and Dietary segments. The Company also did not recognize an opening adjustment to retained earnings as a result of the adoption of the standard. Refer to Note 2—Revenue herein for further information. Leases The guidance under FASB Accounting Standards Codification subtopic ASC 842 Leases (“ASC 842”) became effective and was adopted by the Company as of January 1, 2019, by applying a modified retrospective transition approach which resulted in the capitalization of the Company's existing operating leases as of January 1, 2019. As such, the Company records assets and liabilities on the balance sheet to recognize the rights and obligations arising from leasing arrangements with contractual terms greater than twelve (12) months, as permitted by U.S. GAAP. A leasing arrangement includes any contract which entitles the Company to the right of use of an identified tangible asset where there are no restrictions as to the direct of use of the asset, and the Company obtains substantially all of the economic benefits from the right of use. As of March 31, 2019 and December 31, 2018, the Company was only the lessee of operating lease arrangements. The Company did not recognize an opening adjustment to retained earnings as a result of the adoption of ASC 842, and prior period amounts continue to be reported in accordance with previous guidance. Refer to Note 7—Leases herein for further information. Income Taxes The Company uses the asset and liability method of accounting for income taxes. Under this method, income tax expense or benefits are recognized for the amount of taxes payable or refundable for the current period. The Company accrues for probable tax obligations as required , based on facts and circumstances in various regulatory environments. In addition, deferred tax assets and liabilities are recognized for the expected future tax consequences of temporary differences between the financial reporting and tax bas es of assets and liabilities. When appropriate, valuation allowances are recorded to reduce deferred tax assets to amounts for which realization is more likely than not. Uncertain income tax positions taken or expected to be taken in tax returns are reflected within the Company’s financial statements based on a recognition and measurement process. Earnings per Common Share Basic earnings per common share is computed by dividing income available to common shareholders by the weighted-average number of common shares outstanding for the period. Diluted earnings per common share is computed using the weighted-average number of common shares outstanding and dilutive common shares, such as those issuable upon exercise of stock options and upon the vesting of restricted stock and restricted stock units. Share-Based Compensation The Company estimates the fair value of share-based awards on the date of grant using the Black-Scholes valuation model for stock options and using the share price on the date of grant for restricted stock and restricted stock units. The value of the award is recognized ratably as an expense in the Company’s Consolidated Statements of Comprehensive Income over the requisite service periods, with adjustments made for forfeitures as they occur. Identifiable Intangible Assets and Goodwill Identifiable intangible assets are amortized on a straight-line basis over their respective lives. Goodwill represents the excess of cost over the fair value of net assets of acquired businesses. Management reviews the carrying value of goodwill annually during the fourth quarter to assess for impairment, or more often if events or circumstances indicate that the carrying value may exceed its estimated fair value. No impairment loss was recognized on the Company’s intangible assets or goodwill during the three months ended March 31, 2019. Reclassification Certain prior period amounts have been reclassified to conform to current year presentation. The Company has modified its presentation of interest expense, which is now presented separately in the Consolidated Statements of Comprehensive Income. Correction of Immaterial Errors In the first quarter of 2019, the Company updated its presentation of the tax benefit from equity compensation plans in the Consolidated Statements of Cash Flows. The tax benefit from equity compensation plans is now reflected as a component of the change in income taxes payable, as opposed to an offset to stock-based compensation expense. There was no impact to the Company's net cash provided by operating activities as a result of the correction in the Consolidated Statement of Cash Flows. Additionally, the Company updated its presentation of the income and costs associated with the Company's wholly-owned captive insurance company. Historically, such income and costs were reflected in the Company's revenues and costs of services provided within the Housekeeping segment. Such income and costs are now presented in "Investment and other income, net" in the Consolidated Statements of Comprehensive Income and for segment reporting purposes, those amounts are reflected in Corporate and eliminations. Prior period information has been revised to reflect the changes, which resulted in a $1.2 million and $0.7 million reduction of revenue and costs of services, respectively, in the first quarter 2018 Consolidated Statement of Comprehensive Income, with a corresponding increase of $0.5 million to Investment and other income, net. There was no impact to the Company's net income as a result of the historical errors or the corrections. Concentrations of Credit Risk The Company's financial instruments that are subject to credit risk are cash and cash equivalents, marketable securities, deferred compensation funding and accounts and notes receivable. At March 31, 2019 and December 31, 2018, substantially all of the Company’s cash and cash equivalents and marketable securities were held in one large financial institution located in the United States. The Company’s marketable securities are fixed income investments which are highly liquid and can be readily purchased or sold through established markets. The Company’s clients are concentrated in the healthcare industry and are primarily providers of long-term care. The revenues of many of the Company’s clients are highly reliant on Medicare, Medicaid and third party payors’ reimbursement funding rates. New legislation or changes in existing regulations could directly impact the governmental reimbursement programs in which the clients participate. As a result, the Company may not realize the full effects of such programs until these laws are fully implemented and governmental agencies issue applicable regulations or guidance. Recent Accounting Pronouncements In June 2016, the FASB issued ASU No. 2016-13, Credit Losses - Measurement of Credit Losses on Financial Instruments ("ASC 326"). The standard significantly changes how entities will measure credit losses for most financial assets , including accounts and notes receivables. The standard will replace today’s “incurred loss” approach with an “expected loss” model , under which companies will recognize allowances based on expected rather than incurred losses. Entities will apply the standard’s provisions as a cumulative-effect adjustment to retained earnings as of the beginning of the first reporting period in which the guidance is effective. The standard is effective for interim and annual reporting periods beginning after December 15, 2019. The Company is currently assessing the impact of adopting this standard on the Company’s financial statements and related disclosures.

Revenue from Contract with Customer [Abstract]
Revenue	Note 2—Revenue The Company presents its consolidated revenues disaggregate d by reportable segment, as Management evaluates the nature, amount, timing and uncertainty of the Company’s revenues by segment. Refer to Note 13—Segment Information herein as well as the information below regarding the Company’s reportable segments. Housekeeping Housekeeping accounted for $233.1 million and $245.2 million of the Company’s consolidated revenues for the three months ended March 31, 2019 and 2018, respectively , which represented approximately 49.0% of the Company's revenues in each period . The services provided under this segment include managing clients’ housekeeping departments, which are principally responsible for the cleaning, disinfecting and sanitizing of resident rooms and common areas of the clients’ facilities, as well as the laundering and processing of the bed linens, uniforms, resident personal clothing and other assorted linen items utilized at the clients’ facilities. Upon beginning service with a client facility, the Company typically hire and train the employees previously employed by such facility and assign an on-site manager to supervise and train the front-line personnel and coordinate housekeeping services with other facility support functions in accordance with client requests. Such management personnel also oversee the execution of various cost and quality control procedures including continuous training and employee evaluation, and on-site testing for infection control. Dietary Dietary services accounted for $243.0 million and $255.4 million of the Company’s consolidated revenues for the three months ended March 31, 2019 and 2018, respectively , which represented approximately 51.0% of the Company's revenues in each period . Dietary services consist of managing clients’ dietary departments which are principally responsible for food purchasing, meal preparation and professional dietitian services, which include the development of menus that meet the dietary needs of residents. On-site management is responsible for all daily dietary department activities, with regular support being provided by a District Manager specializing in dietary services, as well as a registered dietitian. The Company also offers clinical consulting services to facilities which if contracted is a service bundled within the monthly service provided to clients. Upon beginning service with a client facility, the Company typically hire and train the employees previously employed by such facility and assign an on-site manager to supervise and train the front-line personnel and coordinate dietitian services with other facility support functions in accordance with client requests. Such management personnel also oversee the execution of various cost- and quality-control procedures including continuous training and employee evaluation. Revenue Recognition A ll of the Company's revenues are derived from contracts with customers. The Company accounts for revenue from contracts with customers in accordance with ASC 606, and as such, the Company recognizes revenue to depict the transfer of promised goods and services to customers in amounts that reflect the consideration to which the Company expects to be entitled in exchange for those goods and services. The Company’s costs of obtaining contracts are not material. The Company performs services and provides goods in accordance with its service agreement contracts with its customers. Such service agreement contracts typically provide for a renewable one year service term, cancellable by either party upon 30 to 90 days' notice, after an initial period of 60 to 120 days. A p erformance obligation is the unit of account under ASC 606 and is defined as a promise in a contract to transfer a distinct good or service to the customer ASC 606. The Company’s Housekeeping and Dietary contracts relate to the provision of bundles of goods, services or both, which represent a series of distinct goods and services and that are substantially the same and that have the same pattern of transfer to the customer. T he Company accounts for the series as a single performance obligation satisfied over time, as the customer simultaneously receives and consumes the benefits of the goods and services provided. Revenue is recognized using the output method, which is based upon the delivery of goods and services to the clients’ facilities. In limited cases, the Company provides goods, services or both, before the execution of a written contract. In these cases, the Company defers the recognition of revenue until a contract is executed. The amount of such deferred revenue was not material as of March 31, 2019 and December 31, 2018. Additionally, all such revenue amounts deferred as of December 31, 2018 were subsequently recognized as revenue during the three months ended March 31, 2019. The transaction price is the amount of consideration to which the Company expects to be entitled in exchange for transferring promised goods or services to its customers. The transaction price does not include taxes assessed or collected. The Company’s contracts detail the fees that the Company charges for the goods and services it provides. For certain contracts which contain a variable component to the transaction price, the Company is required to make estimates of the amount of consideration to which the Company will be entitled, based on variability in resident and patient populations serviced, product usage or quantities consumed. The Company recognizes revenue related to such estimates only when Management determines that there will not be a significant reversal in the amount of revenue recognized. The Company’s contracts generally do not contain significant financing components, as the contracts contain payment terms that are less than one year. The Company allocates the transaction price to each performance obligation, noting that the bundle of goods, services or goods and services provided under each Housekeeping and Dietary contract represents a single performance obligation that is satisfied over time. The Company recognizes the related revenue when it satisfies the performance obligation by transferring a bundle of promised goods, services or both to a customer. Such recognition is on a monthly or weekly basis, as goods are provided and services are performed. In some cases, the Company requires customers to pay in advance for goods and services to be provided. As of March 31, 2019 and December 31, 2018, the value of the contract liabilities associated with customer prepayments was not material. Additionally, all such revenue amounts deferred as of December 31, 2018 were subsequently recognized as revenue during the three months ended March 31, 2019. Transaction Price Allocated to Remaining Performance Obligations The Company recognizes revenue as it satisfies the performance obligations associated with contracts with customers, which due to the nature of the goods and services provided by the Company, are satisfied over time. Contract's may contain transaction prices that are fixed, variable or both. The significant majority of the Company’s contracts with customers have an initial term of one year or less, with renewable one year service terms, cancellable by either party upon 30 to 90 days ' notice after an initial period of 60 to 120 days. For the purpose of disclosing the transaction price allocated to remaining performance obligations, the Company elected to apply practical expedients available under the guidance in ASC 606 to exclude from the calculation future revenues related to contracts with variable consideration that are for a term of one year or less. As of March 31, 2019, the revenue expected to be recognized for the fixed transaction price associated with the remaining performance obligations under the Company’s existing contracts with a term greater than one year is $135.7 million for the remainder of 2019, $181.0 million for 2020, $181.0 million for 2021, $181.0 million for 2022, $181.0 million for 2023 and $30.2 million thereafter.

Accounts and Notes Receivable	Note 3—Accounts and Notes Receivable The Company’s accounts and notes receivable balances consisted of the following as of March 31, 2019 and December 31, 2018: March 31, 2019 December 31, 2018 (in thousands) Short-term Accounts and notes receivable $ 411,736 $ 389,047 Allowance for doubtful accounts (58,630) (47,209) Total net short-term accounts and notes receivable $ 353,106 $ 341,838 Long-term Notes receivable $ 49,291 $ 53,043 Allowance for doubtful accounts (10,000) (10,000) Total net long-term notes receivable $ 39,291 $ 43,043 Total net accounts and notes receivable $ 392,397 $ 384,881 The Company makes credit decisions on a case - by - case basis after reviewing a number of qualitative and quantitative factors related to the specific client as well as current industry variables that may impact that client. There are a variety of factors that impact a client’s ability to pay in accordance with the Company’s service agreements. These factors include, but are not limited to, fluctuating census numbers, litigation costs and the client’s participation in programs funded by federal and state governmental agencies. Deviations in the timing or amounts of reimbursements under those programs can impact the client’s cash flows and their ability to make timely payments. However, the client's obligation to pay the Company in accordance with the service agreements are not contingent upon the client’s cash flows. Notwithstanding the Company’s efforts to minimize its credit risk exposure, the aforementioned factors, as well as other factors that impact client cash flows or ability to make timely payments, could have an indirect, yet material adverse effect on the Company’s results of operations and financial condition. The Company’s net current accounts and notes receivable balance increased from December 31, 2018. Fluctuations in net accounts and notes receivable are generally attributable to a variety of factors including, but not limited to, the timing of cash receipts from customers and the inception, transition or termination of client relationships. The Company deploys significant resources and has invested in tools and processes to optimize Management’s credit and collections efforts. When appropriate, the Company utilizes interest-bearing promissory notes as an alternative to accounts receivable to enhance the collectability of amounts due, by instituting definitive repayment plan s and providing a means by which to further evidence the amounts owed. As of March 31, 2019 and December 31, 2018, the Company had promissory notes outstanding $57.2 million and $63.3 million, respectively, net of reserves. In addition, the Company may assist clients who are adjusting to changes in their cash flows by amending the Company’s agreements from full-service to management-only arrangements, or by modifying contractual payment terms to accommodate clients who have in good faith established clearly-defined plans for addressing cash flow issues. These efforts are intended to minimize the Company’s collections risk while maintaining relationships with the clients.

Allowance for Doubtful Accounts

Allowance for Doubtful Accounts	3 Months Ended

Receivables [Abstract]
Allowance for Doubtful Accounts	Note 4—Allowance for Doubtful Accounts The allowance for doubtful accounts is established when the Company determines that it is probable that receivables have been impaired and the Company can reasonably estimate the amount of the losses. The related provision for bad debts is charged to costs of services provided in the Company’s Consolidated Statements of Comprehensive Income. The allowance for doubtful accounts is evaluated based on the Company’s ongoing review of accounts and notes receivable and is inherently subjective as it requires estimates susceptible to significant revision as more information becomes available. The Company has had varying collections experience with respect to its accounts and notes receivable. The Company has sometimes extended the period of payment for certain clients beyond contractual terms. In order to provide for such collection issues and the general risk associated with the granting of credit terms, the Company recorded bad debt provisions (in Allowance for Doubtful Accounts) of $18.5 million and $37.1 million for the three months ended March 31, 2019 and 2018, respectively. The increase in the allowance for the first quarter 2019 over the Company's normal bad debt provision is related primarily to the restructuring of a Northeast based operator. The decrease in the provision for bad debts period-over-period is primarily related to the provision recognized in the first quarter 2018 related to the corporate restructurings of two privately-held, multi-state operators. In making the credit evaluations, in addition to analyzing and anticipating, where possible, the specific cases described above, Management considers the general collection risk associated with trends in the long-term care industry. The Company establishes credit limits, performs ongoing credit evaluations and monitors accounts to minimize the risk of loss. Despite the Company’s efforts to minimize credit risk exposure, clients could be adversely affected if future industry trends change in such a manner as to negatively impact their cash flows. If the Company’s clients experience a negative impact on their cash flows, it could have a material adverse effect on the Company’s consolidated results of operations and financial condition.

Leases [Abstract]
Leases	Note 7—Leases The Company recognize s right - of - use assets (“ROU Assets”) and lease liabilities (“Lease Liabilities”) for automobiles, office buildings, IT equipment, and small storage units for the temporar y storage of operational equipment. The Company's leases have remaining lease terms ranging from less than 1 year to 10 years , and have extension options ranging from 1 year to 5 years . Most leases include the option to terminate the lease within 1 year. Upon adopting ASC 842, the Company made accounting policy election s using practical expedients offered under the guidance to combine lease and non-lease components within leasing arrangements and to recognize the payments associated with short-term leases in earnings on a straight-line basis over the lease term, with the cost associated with variable lease payments recognized when incurred. These accounting policy elections impact the value of the Company’s ROU Assets and Lease Liabilities. The value of the Company’s ROU Assets is determined as the non-depreciated fair value of its leasing arrangements and is recorded to property and equipment, net on the Company's Consolidated Balance Sheet . The value of the Company’s Lease Liabilities is the present value of fixed lease payments not yet paid , discounted using either the rate implicit in the lease contract if that rate can be determined , or the Company’s incremental borrowing rate ("IBR") and is recorded in Other accrued expenses and Lease liabilities - long-term portion on the Company's Consolidated Balance Sheet . Any future lease payments that are not fixed based on the terms of the lease contract, or fluctuate based on a factor other than an index or rate, are considered variable lease payments and are not included in the value of the Company's ROU Assets or Lease Liabilities. The Company's IBR is determined as the rate of interest that the Company would have to pay to borrow on a collateralized basis over a similar term an amount equal to the lease payments in a similar economic environment. Components of lease expense as well as supplemental information required by ASC 842 are presented below for the three months ended March 31, 2019.

Fair Value Disclosures [Abstract]
Fair Value Measurements	Note 9—Fair Value Measurements The Company’s current assets and current liabilities are financial instruments and most of these items (other than marketable securities and inventories) are recorded at cost in the Consolidated Balance Sheets. The estimated fair value of these financial instruments approximates their carrying value due to their short-term nature. The carrying value of the Company’s line of credit represents the outstanding amount of the borrowings, which approximates fair value. The Company’s financial assets that are measured at fair value on a recurring basis are its marketable securities and deferred compensation funding. The recorded values of all of the financial instruments approximate their current fair values because of their nature, stated interest rates and respective maturity dates or durations. The Company’s marketable securities consist of tax-exempt municipal bonds, which are classified as available-for-sale and are reported at fair value. Unrealized gains and losses associated with these investments are included in other comprehensive income (net of tax) within the Consolidated Statements of Comprehensive Income. The fair value of these marketable securities is classified within Level 2 of the fair value hierarchy, as these securities are measured using quoted prices for identical or similar instruments in markets that are not active, and model-based valuation techniques for which all significant assumptions are observable. Such valuations are determined by a third-party pricing service. For the three months ended March 31, 2019 and 2018, the Company recorded unrealized gains of $1.4 million and unrealized losses of $1.1 million on marketable securities, respectively. For the three months ended March 31, 2019 and 2018, the Company received total proceeds, less the amount of interest received, of $3.5 million and $2.4 million, respectively, from sales of available-for-sale municipal bonds. For the three months ended March 31, 2019 and 2018, these sales resulted in realized gains of less than $0.1 million and realized losses of $0.1 million, respectively, which were recorded in “Other income, net – Investment and interest income ” in the Consolidated Statements of Comprehensive Income. The basis for the sale of these securities was the specific identification of each bond sold during the period. The investments under the funded deferred compensation plan are accounted for as trading securities and unrealized gains or losses are included in earnings. The fair value of these investments are determined based on quoted market prices (Level 1). For the three months ended March 31, 2019 and 2018, the Company's recognized unrealized gains related to equity securities still held at the reporting date of $3.4 million and $0.3 million, respectively.

Stock-based compensation expense is recorded in cost of services and selling, general and administrative expense in the Company’s Consolidated Statements of Comprehensive Income. At March 31, 2019, the unrecognized compensation cost related to unvested stock options and awards was $21.7 million. The weighted average period over which these awards will vest is approximately 3.2 years. 2012 Equity Incentive Plan The Company’s Second Amended and Restated 2012 Equity Incentive Plan (the “Plan”) provides that current or prospective officers, employees, non-employee directors and advisors can receive share-based awards such as stock options, restricted stock, restricted stock units and other stock awards. The Plan seeks to promote the highest level of performance by providing an economic interest in the long-term success of the Company. As of March 31, 2019, 3.6 million shares of common stock were reserved for issuance under the Plan, including 0.6 million shares available for future grant. No stock award will have a term in excess of 10 years. All awards granted under the Plan become vested and exercisable ratably over a 5 years period on each yearly anniversary of the grant date. The Nominating, Compensation and Stock Option Committee of the Board of Directors is responsible for determining the terms of the grants in accordance with the Plan. Stock Options A summary of stock options outstanding under the Plan as of December 31, 2018 and changes during the three months ended March 31, 2019 is as follows: Stock Options Outstanding Number of Shares Weighted Average Exercise Price (in thousands) December 31, 2018 2,121 $ 31.53 Granted 188 $ 40.49 Exercised (68) $ 27.15 Forfeited (5) $ 36.37 Expired (2) $ 13.68 March 31, 2019 2,234 $ 32.42 The weighted average grant-date fair value of stock options granted during the three months ended March 31, 2019 and 2018 was $8.18 and $10.48 per common share, respectively. The total intrinsic value of options exercised during the three months ended March 31, 2019 and 2018 was $0.9 million and $4.2 million, respectively. The fair value of stock option awards granted in 2019 and 2018 was estimated on the date of grant using the Black-Scholes option valuation model with the following assumptions: Three Months Ended March 31, 2019 2018 Risk-free interest rate 2.5 % 2.1 % Weighted average expected life 5.7 years 5.8 years Expected volatility 22.6 % 21.4 % Dividend yield 1.9 % 1.5 % The following table summarizes other information about the stock options at March 31, 2019: March 31, 2019 (amounts in thousands, except per share data) Outstanding: Aggregate intrinsic value $ 9,137 Weighted average remaining contractual life 6.0 years Exercisable: Number of options 1,364 Weighted average exercise price $ 27.84 Aggregate intrinsic value $ 8,912 Weighted average remaining contractual life 4.8 years Restricted Stock Units and Restricted Stock The fair value of outstanding restricted stock units and restricted stock was determined based on the market price of the shares on the date of grant. During the three months ended March 31, 2019, the Company granted 0.2 million restricted stock units with a weighted average grant date fair value of $40.49 per unit. During the three months ended March 31, 2018, the Company granted 0.1 million restricted stock units with a weighted average grant date fair value of $52.06 per share. During the three months ended March 31, 2019 and 2018 , the Company did not grant any restricted stock. A summary of the outstanding restricted stock units and restricted stock as of December 31, 2018 and changes during the three months ended March 31, 2019 is as follows: Restricted Stock Units and Restricted Stock Number Weighted Average Grant Date Fair Value (in thousands) December 31, 2018 241 $ 45.47 Granted 194 $ 40.49 Vested (60) $ 42.91 Forfeited (1) $ 52.06 March 31, 2019 374 $ 43.29 Employee Stock Purchase Plan The Company's Employee Stock Purchase Plan ("ESPP") is currently available through 2021 to all eligible employees. All full-time and part-time employees who work an average of 20 hours per week and have completed two years of continuous service with the Company are eligible to participate. Annual offerings commence and terminate on the respective year’s first and last calendar day. Under the ESPP, the Company is authorized to issue up to 4.1 million shares of its common stock to its employees. Pursuant to such authorization, there are 2.2 million shares available for future grant at March 31, 2019. The expense associated with the options granted under the ESPP during the three months ended March 31, 2019 and 2018 was estimated on the date of grant using the Black-Scholes option valuation model with the following assumptions: Three Months Ended March 31, 2019 2018 Risk-free interest rate 2.57% 1.89% Weighted average expected life (years) 1.0 1.0 Expected volatility 30.8% 20.8% Dividend yield 1.9% 1.4% Deferred Compensation Plan The Company offers a Supplemental Executive Retirement Plan (“SERP”) for executives and certain key employees. The SERP allows participants to defer a portion of their earned income on a pre-tax basis and as of the last day of each plan year, each participant will be credited with a match of a portion of their deferral in the form of the Company’s common stock based on the then-current market value. Under the SERP, the Company is authorized to issue 1.0 million shares of its common stock to its employees. Pursuant to such authorization, the Company has 0.4 million shares available for future grant at March 31, 2019. At the time of issuance, such shares are accounted for at cost as treasury stock. The following table summarizes information about the SERP during the three months ended March 31, 2019 and 2018: Three Months Ended March 31, 2019 2018 (in thousands) SERP expense 1 $ 169 $ 191 Unrealized gain recorded in SERP liability account $ 3,418 $ 231 1.

Income Tax Disclosure [Abstract]
Income Taxes	Note 12—Income Taxes The 2019 estimated annual effective tax rate is expected to be approximately 21% to 23%. The actual annual effective tax rate will be impacted by the tax effects of option exercises or vested awards, which are treated as discrete items in the reporting period in which they occur, and therefore cannot be considered in the calculation of the estimated annual effective tax rate. The impact on the Company’s income tax provision for the three months ended March 31, 2019 for such discrete items was approximately $0.1 million. Differences between the effective tax rate and the applicable U.S. federal statutory rate arise primarily from the effect of state and local income taxes, share-based compensation and tax credits available to the Company. The actual 2019 effective tax rate will likely vary from the estimate depending on the availability of tax credits and the exercise of stock options and vesting of share-based awards. The Company accounts for income taxes using the asset and liability method, which results in recognizing income tax expense based on the amount of income taxes payable or refundable for the current year. Additionally, the Company regularly evaluates the tax positions taken or expected to be taken resulting from financial statement recognition of certain items. Based on the evaluation, there are no significant uncertain tax positions requiring recognition in the Company’s financial statements. The evaluation was performed for the tax years ended December 31, 2013 through 2018 (with regard to U.S. federal income tax returns) and December 31, 2012 through 2018 (with regard to various state and local income tax returns), the tax years which remain subject to examination by major tax jurisdictions as of March 31, 2019.

Segment Reporting [Abstract]
Segment Information	Note 13—Segment Information The Company manages and evaluates its operations in two reportable segments: Housekeeping (housekeeping, laundry, linen and other services) and Dietary (dietary department services). Although both segments serve the same client base and share many operational similarities, they are managed separately due to distinct differences in the type of services provided, as well as the specialized expertise required of the professional management personnel responsible for delivering each segment’s services. Such services are rendered pursuant to discrete service agreements, specific to each reportable segment. The Company’s accounting policies for the segments are generally the same as described in the Company’s significant accounting policies. Differences between the reportable segments’ operating results and other disclosed data and the information in the consolidated financial statements relate primarily to corporate level transactions and recording of transactions at the reportable segment level using other than generally accepted accounting principles. There are certain inventories and supplies that are primarily expensed when incurred within the operating segments, while they are capitalized in the consolidated financial statements. In addition, most corporate expenses such as corporate salary and benefit costs, certain legal costs, bad debt expense, information technology costs, depreciation, amortization of finite-lived intangible assets, share based compensation costs and other corporate-specific costs, are not allocated to the operating segments. There are also allocations for workers’ compensation and general liability expense within the operating segments that differ from the actual expense recorded by the Company under U.S. GAAP.

Earnings Per Share [Abstract]
Earnings Per Common Share	Note 14—Earnings Per Common Share Basic and diluted earnings per common share are computed by dividing net income by the weighted-average number of basic and diluted common shares outstanding, respectively. The weighted-average number of diluted common shares includes the impact of dilutive securities, including outstanding stock options and unvested restricted stock and restricted stock units. The table below reconciles the weighted-average basic and diluted common shares outstanding: Three Months Ended March 31, 2019 2018 (in thousands) Weighted average number of common shares outstanding - basic 74,301 73,913 Effect of dilutive securities 1 418 812 Weighted average number of common shares outstanding - diluted 74,719 74,725 1.

Commitments and Contingencies Disclosure [Abstract]
Other Contingencies	Note 15—Other Contingencies Line of Credit At March 31, 2019, the Company had a $475 million bank line of credit on which to draw for general corporate purposes. Amounts drawn under the line of credit are payable upon demand and generally bear interest at a float rate, based on the Company's leverage ratio, and starting at LIBOR plus 115 basis points (or if LIBOR becomes unavailable, the higher of the Overnight Bank Funding Rate, plus 50 basis points and the Prime Rate). As of both March 31, 2019 and December 31, 2018 there were $30.0 million in borrowings under the line of credit . The line of credit requires the Company to satisfy two financial covenants, with which the Company is in compliance as of March 31, 2019 and expects to remain in compliance. The line of credit expires on December 21, 2023. At March 31, 2019, the Company also had outstanding $62.7 million in irrevocable standby letters of credit, which relate to payment obligations under the Company's insurance programs. In connection with the issuance of the letters of credit, the amount available under the line of credit was reduced by $62.7 million at March 31, 2019. The letters of credit expire on January 2, 2020. Tax Jurisdictions and Matters The Company provides services throughout the continental United States and is subject to numerous state and local taxing jurisdictions. In the ordinary course of business, a jurisdiction may contest the Company’s reporting positions with respect to the application of its tax code to the Company’s services, which could result in additional tax liabilities. The Company has tax matters with various taxing authorities. Because of the uncertainties related to both the probable outcomes and amount of probable assessments due, the Company is unable to make a reasonable estimate of a liability. The Company does not expect the resolution of any of these matters, taken individually or in the aggregate, to have a material adverse effect on the consolidated financial position or results of operations based on the Company’s best estimate of the outcomes of such matters. Legal Proceedings The Company is subject to various claims and legal actions in the ordinary course of business. Some of these matters include payroll and employee-related matters and examinations by governmental agencies. As the Company becomes aware of such claims and legal actions, the Company records accruals for any exposures that are probable and estimable. If adverse outcomes of such claims and legal actions are reasonably possible, Management assesses materiality and provides financial disclosure, as appropriate. As previously disclosed, the Securities and Exchange Commission (“SEC”) is conducting an investigation into the Company's earnings per share (“EPS”) calculation practices. Following receipt of a letter from the SEC in November 2017 regarding its inquiry into those practices followed by a subpoena in March 2018, the Company authorized its outside counsel to conduct an internal investigation, under the direction of the Company’s Audit Committee, into matters related to the SEC subpoena. This investigation was completed in March 2019 and the Company continues to cooperate with the SEC’s investigation. On March 22, 2019, a putative shareholder class action lawsuit was filed against the Company and its Chief Executive Officer in the U.S. District Court for the Eastern District of Pennsylvania. The complaint, which was filed by a plaintiff purportedly on behalf of all purchasers of our securities between April 11, 2017 and March 4, 2019, alleges violations of the federal securities laws in connection with the matters related to the Company's EPS calculation practices. The plaintiffs seek unspecified monetary damages and other relief. While the Company is vigorously defending against all litigation claims asserted, this litigation—along with the ongoing SEC investigation—could result in substantial costs to the Company and a diversion of the Company’s management’s attention and resources, which could harm its business. In addition, the uncertainty of the pending lawsuit or potential filing of additional lawsuits could lead to more volatility and a reduction in the Company’s stock price. Given the early stage of the litigation, at this time the Company is unable to reasonably estimate possible losses or form a judgment that an unfavorable outcome is either probable or remote. It is not currently possible to assess whether or not the outcome of these proceedings may have a material adverse effect on the Company.

Accounting Policies [Abstract]
Nature of Operations	Healthcare Services Group, Inc. (the “Company”) provides management, administrative and operating expertise and services to the housekeeping, laundry, linen, facility maintenance and dietary service departments of the healthcare industry, including nursing homes, retirement complexes, rehabilitation centers and hospitals located throughout the United States. Although the Company does not directly participate in any government reimbursement programs, the Company’s clients receive government reimbursements related to Medicare and Medicaid. Therefore, they are directly affected by any legislation relating to Medicare and Medicaid reimbursement programs. The Company provides services primarily pursuant to full service agreements with its clients. In such agreements, the Company is responsible for the day-to-day management of employees located at the clients’ facilities. The Company also provides services on the basis of management-only agreements for a limited number of clients. The agreements with clients typically provide for renewable one year service terms, cancellable by either party upon 30 to 90 days ’ notice after an initial period of 60 to 120 days . The Company is organized into two reportable segments: housekeeping, laundry, linen and other services (“Housekeeping”), and dietary department services (“Dietary”). Housekeeping consists of managing the clients’ housekeeping departments, which are principally responsible for the cleaning, disinfecting and sanitizing of resident rooms and common areas of a client’s facility, as well as the laundering and processing of the bed linens, uniforms, resident personal clothing and other assorted linen items utilized at a client facility. Dietary consists of managing the clients’ dietary departments, which are principally responsible for food purchasing, meal preparation and dietitian professional services, which includes the development of menus that meet residents’ dietary needs.
Unaudited Interim Financial Data	The accompanying unaudited consolidated financial statements have been prepared in accordance with generally accepted accounting principles in the United States (“U.S. GAAP”) for interim financial information and the requirements of Form 10-Q and Article 10 of Regulation S-X. Accordingly, these consolidated financial statements do not include all of the information and footnotes necessary for a complete presentation of financial position, results of operations and cash flows. However, in the Company’s opinion, all adjustments which are of a normal recurring nature and are necessary for a fair presentation have been reflected in these consolidated financial statements. The balance sheet shown in this report as of December 31, 2018 has been derived from, and does not includ e all of , the disclosures contained in the financial statements for the year ended December 31, 2018. These financial statements should be read in conjunction with the financial statements and notes thereto included in the Company’s Annual Report on Form 10-K for the year ended December 31, 2018. The results of operations for the three months ended March 31, 2019 are not necessarily indicative of the results that may be expected for any future period.
Use of Estimates in Financial Statements	In preparing financial statements in conformity with U.S. GAAP, estimates and assumptions are made that affect the reported amounts of assets and liabilities, disclosures of contingent assets and liabilities, and the reported amounts of revenues and expenses. Actual results could differ from those estimates. Significant estimates are used in determining, but are not limited to, the Company’s allowance for doubtful accounts, accrued insurance claims, valuations, deferred taxes and reviews for potential impairment. The estimates are based upon various factors including current and historical trends, as well as other pertinent industry and regulatory authority information. Management regularly evaluates this information to determine if it is necessary to update the basis for its estimates and to adjust for known changes.
Principles of Consolidation	The accompanying consolidated financial statements include the accounts of Healthcare Services Group, Inc. and its wholly-owned subsidiaries. All significant intercompany transactions and balances have been eliminated in consolidation.
Cash and Cash Equivalents	Cash and cash equivalents are held in U.S. financial institutions or in custodial accounts with U.S. financial institutions. Cash equivalents are defined as short-term, highly liquid investments with a maturity of three months or less at time of purchase that are readily convertible into cash and have insignificant interest rate risk.
Accounts and Notes Receivable	Accounts and notes receivable consist of Housekeeping and Dietary segment receivables from contracts with customers. Accounts receivable initially are recorded at the transaction amount, and are recorded after the Company has an unconditional right to payment where only the passage of time is required before payment is received. Each reporting period, the Company evaluates the collectability of outstanding receivable balances and records an allowance for doubtful accounts representing an estimate of probable losses. Additions to the allowance for doubtful accounts are made by recording a charge to bad debt expense reported in costs of services provided. Notes receivable are initially recorded when accounts receivable are transferred into a promissory note. Notes receivable are recorded as an alternative to accounts receivable to memorialize an unqualified promise to pay a specific sum, typically with interest, in accordance with a defined payment schedule.
Inventories and Supplies	Inventories and supplies include housekeeping, linen and laundry supplies, as well as food provisions and supplies. Non-linen inventories and supplies are stated at cost to approximate a first-in, first-out (FIFO) basis. Linen supplies are amortized on a straight-line basis over their estimated useful life of 24 months .
Revenue Recognition	The Company recognizes revenue from service agreements with customers when or as the promised goods and services are provided to customers. Revenues are reported net of sales taxes that are collected from customers and remitted to taxing authorities. The guidance under the Financial Accounting Standards Board ( " FASB " ) Accounting Standards Codification subtopic 606 Revenue from Contracts with Customers ( " ASC 606 " ) became effective and was adopted by the Company as of January 1, 2018 by applying the modified retrospective method for contracts that were not completed as of January 1, 2018. The standard requires the Company to recognize revenue as the promised goods and services within the terms of the Company’s contracts are performed and satisfied. The amount of revenue recognized by the Company is based on the consideration to which the Company expects to be entitled in exchange for providing the contracted goods and services. The adoption of this standard did not have a material impact on
Leases	The guidance under FASB Accounting Standards Codification subtopic ASC 842 Leases (“ASC 842”) became effective and was adopted by the Company as of January 1, 2019, by applying a modified retrospective transition approach which resulted in the capitalization of the Company's existing operating leases as of January 1, 2019. As such, the Company records assets and liabilities on the balance sheet to recognize the rights and obligations arising from leasing arrangements with contractual terms greater than twelve (12) months, as permitted by U.S. GAAP. A leasing arrangement includes any contract which entitles the Company to the right of use of an identified tangible asset where there are no restrictions as to the direct of use of the asset, and the Company obtains substantially all of the economic benefits from the right of use. As of March 31, 2019 and December 31, 2018, the Company was only the lessee of operating lease arrangements.
Income Taxes	The Company uses the asset and liability method of accounting for income taxes. Under this method, income tax expense or benefits are recognized for the amount of taxes payable or refundable for the current period. The Company accrues for probable tax obligations as required , based on facts and circumstances in various regulatory environments. In addition, deferred tax assets and liabilities are recognized for the expected future tax consequences of temporary differences between the financial reporting and tax bas es of assets and liabilities. When appropriate, valuation allowances are recorded to reduce deferred tax assets to amounts for which realization is more likely than not.
Earnings per Common Share	Basic earnings per common share is computed by dividing income available to common shareholders by the weighted-average number of common shares outstanding for the period. Diluted earnings per common share is computed using the weighted-average number of common shares outstanding and dilutive common shares, such as those issuable upon exercise of stock options and upon the vesting of restricted stock and restricted stock units.
Share-Based Compensation	The Company estimates the fair value of share-based awards on the date of grant using the Black-Scholes valuation model for stock options and using the share price on the date of grant for restricted stock and restricted stock units. The value of the award is recognized ratably as an expense in the Company’s Consolidated Statements of Comprehensive Income over the requisite service periods, with adjustments made for forfeitures as they occur.
Identifiable Intangible Assets and Goodwill	Identifiable intangible assets are amortized on a straight-line basis over their respective lives. Goodwill represents the excess of cost over the fair value of net assets of acquired businesses. Management reviews the carrying value of goodwill annually during the fourth quarter to assess for impairment, or more often if events or circumstances indicate that the carrying value may exceed its estimated fair value.
Reclassification		Certain prior period amounts have been reclassified to conform to current year presentation. The Company has modified its presentation of interest expense, which is now presented separately in the Consolidated Statements of Comprehensive Income. Correction of Immaterial Errors
Concentrations of Credit Risk	The Company's financial instruments that are subject to credit risk are cash and cash equivalents, marketable securities, deferred compensation funding and accounts and notes receivable. At March 31, 2019 and December 31, 2018, substantially all of the Company’s cash and cash equivalents and marketable securities were held in one large financial institution located in the United States. The Company’s marketable securities are fixed income investments which are highly liquid and can be readily purchased or sold through established markets. The Company’s clients are concentrated in the healthcare industry and are primarily providers of long-term care. The revenues of many of the Company’s clients are highly reliant on Medicare, Medicaid and third party payors’ reimbursement funding rates. New legislation or changes in existing regulations could directly impact the governmental reimbursement programs in which the clients participate. As a result, the Company may not realize the full effects of such programs until these laws are fully implemented and governmental agencies issue applicable regulations or guidance.
Recent Accounting Pronouncements	In June 2016, the FASB issued ASU No. 2016-13, Credit Losses - Measurement of Credit Losses on Financial Instruments ("ASC 326"). The standard significantly changes how entities will measure credit losses for most financial assets , including accounts and notes receivables. The standard will replace today’s “incurred loss” approach with an “expected loss” model , under which companies will recognize allowances based on expected rather than incurred losses. Entities will apply the standard’s provisions as a cumulative-effect adjustment to retained earnings as of the beginning of the first reporting period in which the guidance is effective. The standard is effective for interim and annual reporting periods beginning after December 15, 2019. The Company is currently assessing the impact of adopting this standard on the Company’s financial statements and related disclosures.
Segments	The Company’s accounting policies for the segments are generally the same as described in the Company’s significant accounting policies. Differences between the reportable segments’ operating results and other disclosed data and the information in the consolidated financial statements relate primarily to corporate level transactions and recording of transactions at the reportable segment level using other than generally accepted accounting principles. There are certain inventories and supplies that are primarily expensed when incurred within the operating segments, while they are capitalized in the consolidated financial statements. In addition, most corporate expenses such as corporate salary and benefit costs, certain legal costs, bad debt expense, information technology costs, depreciation, amortization of finite-lived intangible assets, share based compensation costs and other corporate-specific costs, are not allocated to the operating segments. There are also allocations for workers’ compensation and general liability expense within the operating segments that differ from the actual expense recorded by the Company under U.S. GAAP. Segment amounts disclosed are prior to elimination entries made in consolidation.
