Accounting Policies [Abstract]
Basis of Presentation and Significant Accounting Policies	Basis of Presentation and Significant Accounting Policies Basis of Presentation IPC Healthcare, Inc. and its wholly-owned subsidiaries (the “Company,” “IPC,” “we,” “us,” and “our”) is a national physician group practice company that operates and manages full-time acute hospitalist and post-acute physician practices. We prepared the accompanying unaudited consolidated financial statements pursuant to the rules and regulations of the Securities and Exchange Commission (SEC) on the same basis as our audited annual financial statements. The consolidated financial statements include all accounts of IPC Healthcare, Inc. and its wholly owned subsidiaries and consolidated professional medical corporations (Professional Medical Corporations) managed under long-term management agreements. Through the management agreements and our relationship with the stockholders of the Professional Medical Corporations, we have exclusive authority over all non-medical decision making related to the ongoing business operations of the Professional Medical Corporations. Further, our rights under the management agreements are unilaterally salable or transferable. Based on the provisions of the agreements, we have determined that the Professional Medical Corporations are variable interest entities (VIE’s), and that we are the primary beneficiary because we have control over the operations of these VIE’s, provide full financial and management support to them, and take all residual benefits and bear all residual losses from their operations. Consequently, we consolidate the revenue and expenses of the Professional Medical Corporations from the date of execution of the agreements. All intercompany balances and transactions have been eliminated in consolidation. In our opinion, these consolidated financial statements reflect all adjustments (consisting only of normal recurring adjustments) necessary to present fairly the financial information set forth therein. Certain information and footnote disclosures normally included in complete financial statements prepared in accordance with U.S. generally accepted accounting principles (GAAP) have been condensed or omitted pursuant to GAAP and SEC rules and regulations, which are applicable to interim financial statements. As a result, the following disclosures should be read in conjunction with our audited consolidated financial statements and notes thereto as of December 31, 2014 included in our Annual Report on Form 10-K for the year ended December 31, 2014 filed with the SEC on February 23, 2015. Revenue Net revenue consists of fees for medical services provided by our affiliated hospitalists under fee-for-service, case rate and other professional fee arrangements with various payors including Medicare, Medicaid, managed care organizations, insurance companies and hospitals. Net revenue is reported in the period in which services are provided at amounts expected to be collected, which excludes contractual discounts and an estimate of uncollectible accounts. Use of Estimates The preparation of financial statements in conformity with GAAP requires us to make estimates and assumptions of the fair value of certain reported amounts of assets, liabilities, revenues and expenses at the date and for the periods that the financial statements are prepared. Significant estimates include the estimated net realizable value of accounts receivable, medical malpractice insurance receivable and payable for known claims, liabilities for claims incurred but not reported (IBNR) related to medical malpractice, fair value of contingent consideration related to business combinations and the analysis of goodwill for impairment. The process of estimating these assets and liabilities involves judgment, which is subject to an inherent degree of uncertainty. Actual results could differ from those estimates. The results of operations for the current interim period are not necessarily indicative of the results for the entire year ending December 31, 2015 . Fair Value of Financial Instruments Our consolidated balance sheets as of June 30, 2015 and December 31, 2014 included the following financial instruments: cash and cash equivalents, accounts receivable, accounts payable and accrued liabilities, payable for practice acquisitions and long-term debt. We consider the carrying amounts of cash and cash equivalents, accounts receivable and accounts payable and accrued liabilities to approximate their fair value because of the relatively short period of time between the origination of these instruments and their expected realization. The carrying amount of our long-term debt borrowed from our line of credit approximated its fair value at June 30, 2015 and December 31, 2014 . Pursuant to GAAP, we determine the fair value of our long-term borrowing using observable inputs, which are defined as Level 2 inputs under GAAP on fair value measures. See Note 3 for the definition of Level 2 inputs under GAAP. Our payable for practice acquisitions consisted of accrued contingent consideration for practice acquisitions. The accrued contingent consideration is carried at fair value largely determined using the income approach with unobservable inputs defined as Level 3 inputs under GAAP. See Note 3 for the definition of Level 3 inputs under GAAP and more information. Goodwill The changes in the carrying amount of goodwill for the six months ended June 30, 2015 are as follows (in thousands): Goodwill - beginning balance at January 1, 2015 $ 408,988 Goodwill acquired during 2015 49,789 Adjustment for prior year transactions (283 ) Goodwill - ending balance at June 30, 2015 $ 458,494 The valuation studies related to the practice acquisitions that occurred in the fourth quarter of 2014 were completed in early 2015, and as a result, the value of contingent consideration liability related to these acquisitions as of the acquisition dates was decreased by $283,000 , along with a corresponding decrease in our goodwill. Medical Malpractice Liability Insurance We record our medical malpractice reserves, on an undiscounted basis, for claims incurred and reported and claims incurred but not reported (IBNR) during the policy period, based on actuarial loss projections using historical loss patterns. For claims incurred and reported, an insurance receivable from our carrier has been recorded pursuant to GAAP. Total accrued medical malpractice reserves and related insurance receivables were as follows (in thousands): June 30, 2015 December 31, 2014 Assets Liabilities Assets Liabilities Insurance Receivable Claims Reserve IBNR Reserve Total Liabilities Insurance Receivable Claims Reserve IBNR Reserve Total Liabilities Current Portion $ 12,322 $ 12,322 $ 567 $ 12,889 $ 12,564 $ 12,564 $ 515 $ 13,079 Long-term Portion 22,999 22,999 26,130 49,129 21,574 21,574 25,665 47,239 Total $ 35,321 $ 35,321 $ 26,697 $ 62,018 $ 34,138 $ 34,138 $ 26,180 $ 60,318 New Accounting Principles In May 2014, the Financial Accounting Standards Board issued a GAAP update "Revenue from Contracts with Customers". This GAAP update requires entities to recognize revenue when it transfers promised goods or services to customers in an amount that reflects what it expects in exchange for the goods or services. This GAAP update also requires more detailed disclosures to enable users of the financial statements to understand the nature, amount, timing and uncertainty of revenue and cash flows arising from contracts with customers. The GAAP update is effective for fiscal years (and interim reporting periods within fiscal years) beginning after December 15, 2016, which is extended to December 15, 2017. We are currently evaluating the impact of the GAAP update on our consolidated financial position, results of operations and cash flows.

Business Acquisitions

Business Acquisitions	6 Months Ended
	Jun. 30, 2015
Business Combinations [Abstract]
Business Acquisitions	Business Acquisitions For practice acquisitions, we recognize all of the assets acquired, liabilities assumed and any contingent consideration at the acquisition-date fair value and expense all transaction related costs. During the six months ended June 30, 2015 , we completed the acquisition of thirteen hospitalist physician practices. In connection with these acquisitions, we recorded goodwill and other identifiable intangible assets consisting of physician and hospital agreements. Goodwill represents the potential business synergy from the combined operations of our existing and acquired practices through an expanded national network of providers, improved managed care contracting, improved collections, identification of growth initiatives and cost savings based upon the significant infrastructure we have developed. Amounts recorded as goodwill and identifiable intangible assets with indefinite lives are not amortizable for GAAP financial reporting purposes but are amortized for tax purposes over 15 years . In addition to the initial consideration paid at the close of each transaction, the asset purchase agreements for ten out of the thirteen acquisitions completed during the six months ended June 30, 2015 provide for contingent consideration to be paid, which is generally based upon the achievement of certain operating results of the acquired practices as of certain measurement dates. These additional payments are not contingent upon the future employment of the sellers. The contingent consideration for four acquisitions completed during the three months ended June 30, 2015 was recorded on a provisional basis pending completion of the valuation studies as of the acquisition dates. We estimate the fair value of contingent consideration to be paid based on discounted projected earnings of the acquired practices as of certain measurement dates. The discount rate that we use consists of a risk-free U.S. Treasury bond yield plus a Company specific credit spread which we believe is acceptable by willing market participants. The following table summarizes the total amounts recorded during the six months ended June 30, 2015 related to the acquisition of hospitalist practices (in thousands): Acquired assets, net of assumed liabilities – paid and accrued: Goodwill - current year transactions $ 49,789 Other intangible assets 630 Fixed assets 7 Total acquired assets - current year 50,426 Goodwill - adjustment for prior year transactions (283 ) 50,143 Cash paid for acquisitions: Current year transactions (41,125 ) Contingent consideration (4,706 ) Total cash paid for acquisitions (45,831 ) Change in accrued contingent consideration 4,884 Net change in payable for practice acquisitions 9,196 Payable for practice acquisitions, beginning of period 44,911 Payable for practice acquisitions, end of period $ 54,107

Fair Value Measurement

Fair Value Disclosures [Abstract]
Fair Value Measurement	Fair Value Measurement Some of our liabilities are measured and recorded at fair value, which is defined as the price that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date (an exit price). The established fair value hierarchy distinguishes between market participant assumptions based on market data obtained from sources independent of the reporting entity (Levels 1 and 2) and the reporting entity’s own assumptions about market participant assumptions (Level 3). This hierarchy is used to measure fair value as follows: • Level 1 inputs utilize quoted prices in active markets for identical assets or liabilities. • Level 2 inputs include quoted prices for similar assets and liabilities in active markets; quoted prices in markets that are not active; and other inputs that are observable or can be corroborated by observable market data for the asset or liability. • Level 3 inputs are unobservable inputs for the asset or liability that are supported by little or no market activity. The following table presents our liabilities measured at fair value on a recurring basis as of June 30, 2015 (in thousands): Quoted Price In Active Markets for Identical Instruments (Level 1) Significant Other Observable Inputs (Level 2) Significant Unobservable Inputs (Level 3) Total Balance Accrued contingent consideration for practice acquisitions (included in payable for practice acquisitions) $ — $ — $ 54,107 $ 54,107 The following table presents a rollforward of our liabilities measured at fair value on a recurring basis using significant unobservable inputs (Level 3) for the three and six months ended June 30, 2015 (in thousands): Three Months Ended Six Months Ended Accrued contingent consideration for practice acquisitions Beginning balance $ 56,308 $ 44,911 Addition through acquisition transactions 1,262 9,301 Adjustment for prior year transactions — (283 ) Change in accrued contingent consideration 505 4,884 Payments (3,968 ) (4,706 ) Ending balance $ 54,107 $ 54,107 The fair value of our accrued contingent consideration is determined using widely accepted valuation techniques, which include the income approach for estimating future consideration to be paid based on projected earnings of our acquired practices as of specified measurement dates. The income approach involves the use of a probability-weighted discounted cash flow model based on significant inputs not observable in the market. The significant inputs include discount rates of 1.27% to 1.90% , 100% probability of achieving the estimated projected earnings, and 10% to 80% probability of achieving certain other objectives. Because our accrued contingent consideration is generally based on a certain multiple of earnings of the acquired practices during a specified measurement period, a moderate change in such projected earnings may result in a material change to the fair value of such contingent consideration liability with a corresponding adjustment to income from operations. We reassess our projected earnings and the related fair value of our accrued contingent consideration for practice acquisitions on a quarterly basis.

Debt Disclosure [Abstract]
Debt	Debt Our secured revolving credit agreement (Credit Facility) provides a revolving line of credit of $125.0 million and contains an “accordion” feature that allows an increase of up to $25.0 million to the Credit Facility with lender approval. The Credit Facility has a maturity date of August 4, 2016 and is available for working capital, practice acquisitions, capital expenditures and general business expenses. As of June 30, 2015 , we had borrowings of $90.0 million and letters of credit of $0.3 million outstanding, and $34.7 million available under the Credit Facility. The revolving line of credit is limited by a formula based on a certain multiple times the trailing twelve months of earnings before interest, taxes, depreciation, amortization and certain non-cash items. Interest rate options for each borrowing under the Credit Facility, to be selected by us at the time of each borrowing, include either LIBOR plus 0.75% to 1.75% , or the lender’s prime rate plus 0% to 0.75% , both based on a leverage ratio. We pay an unused commitment fee equal to 0.25% per annum on the difference between the revolving line capacity and the average balance outstanding during the year. Outstanding amounts advanced to us under the revolving line of credit are repayable on or before the maturity date. The interest rate for our borrowings under the Credit Facility at June 30, 2015 was 0.9375% per annum. The Credit Facility is guaranteed by our subsidiaries and affiliated Professional Medical Corporations and limited liability companies, and is secured by substantially all of our and our guarantors’ tangible and intangible assets. The Credit Facility includes various customary financial covenants and restrictions, as well as customary remedies for our lenders following an event of default. As of June 30, 2015 , we were in compliance with such financial covenants and restrictions.

Income Taxes	Income Taxes The following table sets forth our income tax provisions and effective tax rates for the three and six months ended June 30, 2015 and 2014 (dollars in thousands): Three Months Ended June 30, Six Months Ended June 30, 2015 2014 2015 2014 Income tax provision $ 5,364 $ 6,586 $ 9,291 $ 12,963 Effective tax rate 38.0 % 38.3 % 38.0 % 38.3 % The effective tax rates differ from the statutory U.S. federal income tax rate of 35.0% due primarily to state income taxes. Our accounting policy is to include interest and penalties related to income tax liabilities in income tax expense. As of June 30, 2015 , we did not have any estimated interest and penalties related to uncertain tax positions. The tax years 2009 to 2013 remain open to examination by the major taxing jurisdictions to which we are subject. The statute of limitations for tax years 1999 to 2008 has expired, except that the tax year 1999 is subject to adjustment of net operating losses by the Internal Revenue Service. We are subject to taxation in the United States and various state jurisdictions. We are currently subject to one state tax examination for the tax year of 2009 and two federal tax examinations for the tax year of 2013. The outcome of the examinations cannot be predicted with certainty; however, we believe that the ultimate resolution will not have a material effect on our consolidated financial position, results of operations, or cash flows. We make our best estimate of the tax rate expected to be applicable for the full fiscal year. The rate so determined is used to compute our income tax expense for an interim period.

Disclosure of Compensation Related Costs, Share-based Payments [Abstract]
Stock-Based Compensation	Stock-Based Compensation At June 30, 2015 , we had a stock-based employee compensation program, for which we had reserved a total of 4,943,170 common shares for issuance. Under our 2012 Equity Participation Plan (Equity Plan), which was approved by our stockholders on June 7, 2012, a total of 1,422,130 shares of our common stock were available for issuance and no new awards will be issued under any previous equity participation plans. As of June 30, 2015 , there were 529,851 shares of our common stock available for future grants under our Equity Plan, which included the canceled and forfeited shares issued under previous equity participation plans. All option awards previously granted were issued with exercise prices equal to the closing price of our common stock on the NASDAQ Global Select Market on the dates of the grant. The options under the Equity Plan generally vest over a four -year period from date of grant, and options terminate on the 10th anniversary of the agreement date for all grants issued before January 1, 2013 and on the 7th anniversary of the agreement date for all grants issued after December 31, 2012. Restricted stock awards generally vest over a four -year period from date of the award. Performance stock units granted prior to 2015 generally vest over two to three years from date of the award based on the expected level of achievement of certain operational goals that will be obtained and adjusted as appropriate to reflect actual shares issued. Performance stock units granted in 2015 generally vest over three to four years from date of the award based on the expected level of achievement of certain market conditions that will be obtained and adjusted as appropriate to reflect actual shares issued. Stock-based compensation expense is recognized over the period when the options, restricted stock awards, performance stock awards and our employee stock purchase plan shares vest, which is included in total general and administrative expenses as follows (in thousands): Three Months Ended June 30, Six Months Ended June 30, 2015 2014 2015 2014 Total stock-based compensation expense $ 1,784 $ 2,059 $ 3,688 $ 4,024 Tax benefit from stock-based compensation expense (678 ) (789 ) (1,401 ) (1,541 ) Total stock-based compensation expense, net of tax $ 1,106 $ 1,270 $ 2,287 $ 2,483 As of June 30, 2015 , total unrecognized compensation costs related to non-vested stock-based compensation arrangements granted under our Equity Plan and previous equity participation plans and the weighted-average period of years expected to recognize those costs are as follows (dollars in thousands): Total Unrecognized Compensation Cost Weighted -average Remaining Recognition Period (Years) Stock option $ 903 1.47 Restricted/Performance stock $ 11,916 2.47 The grant date fair value of each restricted stock award or performance stock units with operational goals is based on the closing stock price on the grant date of the award as reported by NASDAQ Global Select Market. The grant date fair value of performance stock units with market conditions is determined using a Monte-Carlo simulation model. Key assumptions in the Monte-Carlo simulation model are the risk-free interest rate, expected volatility and correlation coefficient.

Earnings Per Share [Abstract]
Earnings Per Share	Earnings Per Share Basic net income per share is calculated by dividing net income for the period by the weighted-average number of common shares outstanding during the period. Diluted net income per share is calculated by dividing net income for the period by the weighted average number of shares outstanding during the period plus the dilutive effect of our outstanding stock awards and shares issuable under our employee stock purchase plan using the treasury stock method. The calculations of basic and diluted net income per share for the three and six months ended June 30, 2015 and 2014 are as follows (dollars in thousands, except for per share data): Three Months Ended Six Months Ended 2015 2014 2015 2014 Basic: Net income attributable to common stockholders $ 8,750 $ 10,609 $ 15,160 $ 20,883 Weighted average number of common shares outstanding 17,388,646 17,123,840 17,345,822 17,089,410 Basic net income per share attributable to common stockholders $ 0.50 $ 0.62 $ 0.87 $ 1.22 Diluted: Net income attributable to common stockholders $ 8,750 $ 10,609 $ 15,160 $ 20,883 Weighted average number of common shares outstanding 17,388,646 17,123,840 17,345,822 17,089,410 Weighted average number of dilutive common share equivalents from options to purchase common stock 487,076 392,098 476,568 467,535 Common shares and common share equivalents 17,875,722 17,515,938 17,822,390 17,556,945 Diluted net income per share $ 0.49 $ 0.61 $ 0.85 $ 1.19 Outstanding stock options and performance stock units that have an above-market exercise price or that are anti-dilutive under the treasury stock method, are excluded from our diluted computation.

Commitments and Contingencies Disclosure [Abstract]
Commitments and Contingencies	Commitments and Contingencies Legal In the ordinary course of our business, we become involved in pending and threatened legal actions and proceedings, most of which involve claims of medical malpractice related to medical services provided by our affiliated clinicians. We may also become subject to other lawsuits, which could involve significant claims and/or significant defense costs. We believe, based upon our review of pending actions and proceedings that the outcome of such legal actions and proceedings will not have a material adverse effect on our business, consolidated financial position, results of operations, or cash flows. The outcome of such actions and proceedings, however, cannot be predicted with certainty and an unfavorable resolution of one or more of them could have a material adverse effect on our business, consolidated financial position, results of operations, or cash flows in a future period. Government Claim On June 7, 2010, we received a civil investigative demand (CID) issued by the Department of Justice (DOJ), U.S. Attorney’s Office for the Northern District of Illinois. The CID requested information concerning claims that we have submitted to Medicare and Medicaid. The CID covered the period from January 1, 2003, through June 4, 2010, and requested production of a range of documents relating to our Medicare and Medicaid participation, physician arrangements, operations, billings and compliance programs. We believe we have a strong compliance focus, and that we operate with appropriate billing policies, procedures, provider training, and compliance programs and controls. We produced responsive documents and were in contact with representatives of the DOJ who informed us that the inquiry related to a qui tam whistleblower action filed under court seal in the U.S. District Court for the Northern District of Illinois (Chicago). We also were informed that several state attorneys general were examining our Medicaid claims in coordination with the DOJ. Though we cooperated with the government’s investigation and would welcome a resolution to this matter, we are now in active litigation with the federal government regarding this matter and intend to contest the case vigorously. On December 6, 2013, the U.S. District Court partially lifted the seal on the civil False Claims Act case related to this investigation. The unsealed portions of the Court docket at that time included the whistleblower’s Complaint, which contains allegations of improper billing to Medicare and Medicaid, a Notice of Election to Intervene filed by the federal government and a Notice of Election to Decline Intervention filed by the State of Illinois and 12 other states that participated in the investigation. On June 16, 2014, the federal government filed its Complaint in Intervention against IPC and several of its subsidiaries in the U.S. District Court. The Complaint in Intervention contains allegations of improper billing to Medicare, Medicaid and other federal healthcare programs from January 1, 2003 to the present, seeks to recover treble damages and civil penalties under the civil False Claims Act, and seeks to recover damages under the common law theories of payment by mistake and unjust enrichment. On August 13, 2014, IPC and the IPC subsidiary defendants filed a joint motion to dismiss the Complaint in Intervention or, in the alternative, to sever claims against the defendants. The federal government filed its response on September 18, 2014, to which the defendants replied on September 25, 2014. The court’s decision, which was filed on February 17, 2015, granted the motion to dismiss in part and denied it in part. The Court’s Opinion and Order dismissed the 29 IPC subsidiary and affiliate defendants without prejudice, but the Court denied the request to dismiss IPC, which remains the sole defendant in the lawsuit. The parties are engaged in active discovery. It is not possible to predict when this matter may be resolved, the time or resources that we will need to devote to this litigation, or what impact, if any, the outcome of this matter might have on our business, consolidated financial position, results of operations, or cash flows. Derivative Lawsuit Although the underlying government lawsuit is still in an early stage and no liability has been found by a court, on October 20 and 24, 2014, shareholder derivative lawsuits were filed in the Court of Chancery of the State of Delaware against certain of our current and former directors and officers. We are named as a nominal defendant in both suits. The actions both assert alleged breaches of fiduciary duties related to our billing practices, and incorporate allegations from the False Claims Act case. The lawsuits seek a variety of relief, including monetary damages and injunctive relief. On December 4, 2014, the derivative lawsuits were consolidated into one lawsuit. On April 15, 2015, we filed a motion to stay the consolidated derivative lawsuit, pending the resolution of the False Claims Act case. That motion remains pending. The litigation is in an early stage and it is not possible to predict when this matter may be resolved, the time or resources that we will need to devote to this litigation, or what impact, if any, the outcome of this matter might have on our business, consolidated financial position, results of operations, or cash flows.

Accounting Policies [Abstract]
Basis of Presentation	Basis of Presentation IPC Healthcare, Inc. and its wholly-owned subsidiaries (the “Company,” “IPC,” “we,” “us,” and “our”) is a national physician group practice company that operates and manages full-time acute hospitalist and post-acute physician practices. We prepared the accompanying unaudited consolidated financial statements pursuant to the rules and regulations of the Securities and Exchange Commission (SEC) on the same basis as our audited annual financial statements. The consolidated financial statements include all accounts of IPC Healthcare, Inc. and its wholly owned subsidiaries and consolidated professional medical corporations (Professional Medical Corporations) managed under long-term management agreements. Through the management agreements and our relationship with the stockholders of the Professional Medical Corporations, we have exclusive authority over all non-medical decision making related to the ongoing business operations of the Professional Medical Corporations. Further, our rights under the management agreements are unilaterally salable or transferable. Based on the provisions of the agreements, we have determined that the Professional Medical Corporations are variable interest entities (VIE’s), and that we are the primary beneficiary because we have control over the operations of these VIE’s, provide full financial and management support to them, and take all residual benefits and bear all residual losses from their operations. Consequently, we consolidate the revenue and expenses of the Professional Medical Corporations from the date of execution of the agreements. All intercompany balances and transactions have been eliminated in consolidation. In our opinion, these consolidated financial statements reflect all adjustments (consisting only of normal recurring adjustments) necessary to present fairly the financial information set forth therein. Certain information and footnote disclosures normally included in complete financial statements prepared in accordance with U.S. generally accepted accounting principles (GAAP) have been condensed or omitted pursuant to GAAP and SEC rules and regulations, which are applicable to interim financial statements. As a result, the following disclosures should be read in conjunction with our audited consolidated financial statements and notes thereto as of December 31, 2014 included in our Annual Report on Form 10-K for the year ended December 31, 2014 filed with the SEC on February 23, 2015.
Revenue	Revenue Net revenue consists of fees for medical services provided by our affiliated hospitalists under fee-for-service, case rate and other professional fee arrangements with various payors including Medicare, Medicaid, managed care organizations, insurance companies and hospitals. Net revenue is reported in the period in which services are provided at amounts expected to be collected, which excludes contractual discounts and an estimate of uncollectible accounts.
Use of Estimates	Use of Estimates The preparation of financial statements in conformity with GAAP requires us to make estimates and assumptions of the fair value of certain reported amounts of assets, liabilities, revenues and expenses at the date and for the periods that the financial statements are prepared. Significant estimates include the estimated net realizable value of accounts receivable, medical malpractice insurance receivable and payable for known claims, liabilities for claims incurred but not reported (IBNR) related to medical malpractice, fair value of contingent consideration related to business combinations and the analysis of goodwill for impairment. The process of estimating these assets and liabilities involves judgment, which is subject to an inherent degree of uncertainty. Actual results could differ from those estimates. The results of operations for the current interim period are not necessarily indicative of the results for the entire year ending December 31, 2015 .
Fair Value of Financial Instruments	Fair Value of Financial Instruments Our consolidated balance sheets as of June 30, 2015 and December 31, 2014 included the following financial instruments: cash and cash equivalents, accounts receivable, accounts payable and accrued liabilities, payable for practice acquisitions and long-term debt. We consider the carrying amounts of cash and cash equivalents, accounts receivable and accounts payable and accrued liabilities to approximate their fair value because of the relatively short period of time between the origination of these instruments and their expected realization. The carrying amount of our long-term debt borrowed from our line of credit approximated its fair value at June 30, 2015 and December 31, 2014 . Pursuant to GAAP, we determine the fair value of our long-term borrowing using observable inputs, which are defined as Level 2 inputs under GAAP on fair value measures. See Note 3 for the definition of Level 2 inputs under GAAP. Our payable for practice acquisitions consisted of accrued contingent consideration for practice acquisitions. The accrued contingent consideration is carried at fair value largely determined using the income approach with unobservable inputs defined as Level 3 inputs under GAAP. See Note 3 for the definition of Level 3 inputs under GAAP and more information.
Medical Malpractice Liability Insurance	Medical Malpractice Liability Insurance We record our medical malpractice reserves, on an undiscounted basis, for claims incurred and reported and claims incurred but not reported (IBNR) during the policy period, based on actuarial loss projections using historical loss patterns. For claims incurred and reported, an insurance receivable from our carrier has been recorded pursuant to GAAP.
New Accounting Principles	New Accounting Principles In May 2014, the Financial Accounting Standards Board issued a GAAP update "Revenue from Contracts with Customers". This GAAP update requires entities to recognize revenue when it transfers promised goods or services to customers in an amount that reflects what it expects in exchange for the goods or services. This GAAP update also requires more detailed disclosures to enable users of the financial statements to understand the nature, amount, timing and uncertainty of revenue and cash flows arising from contracts with customers. The GAAP update is effective for fiscal years (and interim reporting periods within fiscal years) beginning after December 15, 2016, which is extended to December 15, 2017. We are currently evaluating the impact of the GAAP update on our consolidated financial position, results of operations and cash flows.
