| Basis of Presentation and New Accounting Pronouncements |
The accompanying unaudited Condensed Consolidated Financial Statements of the Company and the notes thereto presented in this Form 10-Q have been prepared in accordance with the rules and regulations of the Securities and Exchange Commission (“SEC”) applicable to interim financial statements, and do not include all disclosures required by accounting principles generally accepted in the United States of America (“GAAP”) for complete financial statements. In the opinion of management, these financial statements include all adjustments, consisting only of normal recurring adjustments, necessary for a fair statement of the results of interim periods. The financial statements include all the accounts of MEDNAX, Inc. and its consolidated subsidiaries (collectively, “MDX”) together with the accounts of MDX’s affiliated business corporations or professional associations, professional corporations, limited liability companies and partnerships (the “affiliated professional contractors”). Certain subsidiaries of MDX have contractual management arrangements with its affiliated professional contractors, which are separate legal entities that provide physician services in certain states and Puerto Rico. The terms “MEDNAX” and the “Company” refer collectively to MEDNAX, Inc., its subsidiaries and the affiliated professional contractors. The Company is a party to a joint venture in which it owns a 37.5% economic interest and a second joint venture in which it owns a 49.0% economic interest. The Company accounts for these joint ventures under the equity method of accounting because the Company exercises significant influence over, but does not control, these entities. The consolidated results of operations for the interim periods presented are not necessarily indicative of the results to be experienced for the entire fiscal year. In addition, the accompanying unaudited Condensed Consolidated Financial Statements and the notes thereto should be read in conjunction with the Consolidated Financial Statements and the notes thereto included in the Company’s most recent Annual Report on Form 10-K (the “Form 10-K”). On November 1, 2018, the Company announced the initiation of a process to potentially divest the Company’s management services service line to allow the Company to focus on its core physician services business. The Company determined that the criterion to classify the management services service line as assets held for sale within the Company’s Consolidated Balance Sheets effective March 31, 2019 were met, and accordingly, the assets and liabilities of that service line were classified as current assets and liabilities held for sale at March 31, 2019. In addition, in accordance with accounting guidance for discontinued operations, the expected divestiture of the management services service line was deemed to represent a fundamental strategic shift that will have a major effect on the Company’s operations, and accordingly, the operating results of the service line were reported as discontinued operations in the Company’s Consolidated Statements of Income for the three months ended March 31, 2019. Reclassifications have been made to certain prior period financial statements and footnote disclosures to reflect the impact of discontinued operations. See note 6 for more information. Recently Adopted Accounting Pronouncements In February 2016, the accounting guidance related to leases was issued that require an entity to recognize leased assets and the rights and obligations created by those leased assets on the balance sheet and to disclose key information about the entity’s leasing arrangements. This guidance became effective for the Company on January 1, 2019. The adoption of this guidance had a material impact on the Company’s Consolidated Balance Sheets and related disclosures, resulting from the recognition of significant right of use assets and related liabilities, primarily related to its operating lease arrangements for space in hospitals and certain other facilities for its business and medical offices. See note 8 for more information. |

| Cash Equivalents and Investments |
As of March 31, 2019 and December 31, 2018, the Company’s cash equivalents consisted entirely of money market funds totaling $2.5 million and $0.5 million, respectively. Investments consisted of municipal debt securities, federal home loan securities and certificates of deposit. During the three months ended March 31, 2019, the Company changed its accounting policy for and the classification of its investments from held-to-maturity to available for sale. Although there is no stated expectation that the investments will be sold within one year, the investments are available for use, if needed, and accordingly are classified as short-term. Such investments are carried at fair value with any unrealized gains and losses reported as a component of other accumulated comprehensive income or loss. Prior to January 1, 2019, the Company classified its investments as held-to-maturity and carried such investments at amortized cost. Investments with remaining maturities of less than one year were classified as short-term and investments classified as long-term had maturities of one year to five years. Investments held at March 31, 2019 and December 31, 2018 are summarized as follows (in thousands):

| Fair Value Disclosures |
The accounting guidance establishes a fair value hierarchy that prioritizes valuation inputs into three levels based on the extent to which inputs used in measuring fair value are observable in the market. Each fair value measurement is reported in one of three levels: Level 1 – inputs are based upon unadjusted quoted prices for identical instruments traded in active markets. Level 2 – inputs are based upon quoted prices for similar instruments in active markets, 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 in the market or can be corroborated by observable market data for substantially the full term of the assets or liabilities. Level 3 – inputs are generally unobservable and typically reflect management’s estimates of assumptions that market participants would use in pricing the asset or liability. The fair values are therefore determined using model-based techniques that include option pricing models, discounted cash flow models, and similar techniques. The following table presents information about the Company’s financial instruments that are accounted for at fair value on a recurring basis at March 31, 2019 and December 31, 2018 (in thousands):
The following table presents information about the Company’s financial instruments that are not carried at fair value at March 31, 2019 and December 31, 2018 (in thousands):
The carrying amounts of cash equivalents, accounts receivable and accounts payable and accrued expenses approximate fair value due to the short maturities of the respective instruments. The carrying value of the line of credit approximates fair value. If the Company’s line of credit was measured at fair value, it would be categorized as Level 2 in the fair value hierarchy. |

| Accounts Receivable and Net Revenue |
Accounts receivable, net consists of the following (in thousands):
Patient service revenue is recognized at the time services are provided by the Company’s affiliated physicians. The Company’s performance obligations related to the delivery of services to patients are satisfied at the time of service. Accordingly, there are no performance obligations that are unsatisfied or partially unsatisfied at the end of the reporting period with respect to patient service revenue. Almost all of the Company’s patient service revenue is reimbursed by government-sponsored healthcare programs (“GHC Programs”) and third-party insurance payors. Payments for services rendered to the Company’s patients are generally less than billed charges. The Company monitors its revenue and receivables from these sources and records an estimated contractual allowance to properly account for the anticipated differences between billed and reimbursed amounts. Accordingly, patient service revenue is presented net of an estimated provision for contractual adjustments and uncollectibles. The Company estimates allowances for contractual adjustments and uncollectibles on accounts receivable based upon historical experience and other factors, including days sales outstanding (“DSO”) for accounts receivable, evaluation of expected adjustments and delinquency rates, past adjustments and collection experience in relation to amounts billed, an aging of accounts receivable, current contract and reimbursement terms, changes in payor mix and other relevant information. Contractual adjustments result from the difference between the physician rates for services performed and the reimbursements by GHC Programs and third-party insurance payors for such services. Collection of patient service revenue the Company expects to receive is normally a function of providing complete and correct billing information to the GHC Programs and third-party insurance payors within the various filing deadlines and typically occurs within 30 to 60 days of billing. Some of the Company’s hospital agreements require hospitals to pay the Company administrative fees. Some agreements provide for fees if the hospital does not generate sufficient patient volume in order to guarantee that the Company receives a specified minimum revenue level. The Company also receives fees from hospitals for administrative services performed by its affiliated physicians providing medical director or other services at the hospital. The following table summarizes the Company’s net revenue by category (in thousands):
The approximate percentage of net patient service revenue by type of payor was as follows:

During the three months ended March 31, 2019, the Company completed the acquisition of one neonatology physician group practice for $4.3 million. This acquisition expanded the Company’s national network of physician practices. In connection with this acquisition, the Company recorded goodwill of $4.1 million and other intangible assets consisting primarily of physician and hospital agreements of $0.2 million. The Company expects that the goodwill recorded during the three months ended March 31, 2019 will be deductible for tax purposes. In addition, the Company paid $1.4 million for contingent consideration in connection with a prior period acquisition. The Company also recorded a decrease of $4.0 million related to the change in fair value of a contingent consideration agreement for which the probability of the achievement of certain performance measures was updated during the three months ended March 31, 2019. This change in fair value of contingent consideration was recorded within operating expenses. |

| Disposal Groups, Including Discontinued Operations, Disclosure |
On November 1, 2018, the Company announced the initiation of a process to potentially divest of its management services service line to allow the Company to focus on its core physician services business. The Company determined that the criterion to classify the management services service line as assets held for sale within the Company’s Consolidated Balance Sheets effective March 31, 2019 were met. Accordingly, the assets and liabilities of that service line were classified as current assets and liabilities held for sale at March 31, 2019 as the Company expects to divest of the management services organization within the next twelve months, although there is no assurance that any such divestiture will occur. The classification to assets held for sale impacted the net book value of the assets and liabilities expected to be transferred upon sale. The estimated fair value of the management services service line was determined based on a range of market multiples and other assumptions along with estimated broker, accounting, legal and other costs to sell. The Company deemed the carrying amount of other assets within the service line, specifically accounts receivable and property and equipment, to represent fair value and therefore recorded a non-cash charge of $285.0 million against goodwill, which represented the difference between the estimated fair value of the management services service line and the carrying amount of the net assets held for sale. Recognition of the charge against goodwill resulted in a tax benefit which generated an additional $36.6 million deferred tax asset that increased the fair value of the service line. An incremental non-cash charge is then required to reduce the service line to its previously determined fair value. Accordingly, the Company recorded the incremental non-cash charge of $36.6 million for a total non-cash charge of $321.6 million, reducing the goodwill balance of the management services service line to zero. Upon completion of a divestiture, the Company could record an additional gain or loss on disposal at the time final net proceeds are determined. In addition, in accordance with accounting guidance for discontinued operations, the expected divestiture of the management services service line was deemed to represent a fundamental strategic shift that will have a major effect on the Company’s operations, and accordingly, the operating results of the service line were reported as discontinued operations in the Company’s Consolidated Statements of Income for the three months ended March 31, 2019 with prior periods recast to conform with the current period presentation. The following table is a reconciliation of the major classes of assets and liabilities classified as assets and liabilities held for sale in the accompanying Consolidated Balance Sheets representing the management services service line as of March 31, 2019 and December 31, 2018 (in thousands):

| Leases of Lessee Disclosure |
Effective January 1, 2019, the Company adopted the new accounting guidance using the modified retrospective method of applying the new guidance at the adoption date. The Company elected practical expedients permitted under the transition provisions, which allowed the Company to carryforward historical assessments of whether contracts are or contain leases and lease classification. Beginning with January 1, 2019, the Company’s financial position is presented under the new guidance, while the prior period financial statements were not adjusted and continue to be reported in accordance with the previous guidance. The Company primarily leases property under operating leases and has one material equipment operating lease for an aircraft. The Company’s property leases are primarily for its regional, medical and business offices, storage space and temporary housing for medical staff. For leases with terms greater than 12 months, the Company records the related asset and obligation at the present value of the lease payment using a discount rate that reflects the Company’s estimated incremental borrowing rate. Certain of the Company’s leases include rental escalation clauses and renewal options that are factored into the determination of lease payments when appropriate. Operating leases for office equipment are not material, and therefore are excluded from the Company’s Consolidated Balance Sheet. Finance leases are not material but will continue to be reported on the Company’s Consolidated Balance Sheets with the right-of-use assets included in property and equipment, net, and the liabilities included in current portion of long-term debt and finance lease obligations. The table below presents the operating lease-related right-of-use assets and related liabilities recorded on the Company’s balance sheet and the weighted average remaining lease term and discount rate as of March 31, 2019 (dollars in thousands):

| Disclosure of Compensation Related Costs, Share-based Payments [Abstract] | ||||
| Stock Incentive Plans and Stock Purchase Plans |
The Company’s Amended and Restated 2008 Incentive Compensation Plan, as amended (the “Amended and Restated 2008 Incentive Plan”) provides for grants of stock options, stock appreciation rights, restricted stock, deferred stock, and other stock-related awards and performance awards that may be settled in cash, stock or other property. Under the Amended and Restated 2008 Incentive Plan, options to purchase shares of common stock may be granted at a price not less than the fair market value of the shares on the date of grant. The options must be exercised within 10 years from the date of grant and generally become exercisable on a pro rata basis over a three-year period from the date of grant. The Company issues new shares of its common stock upon exercise of its stock options. Restricted stock awards generally vest over periods of three years upon the fulfillment of specified service-based conditions and in certain instances performance-based conditions. Deferred stock awards generally vest upon the satisfaction of specified performance-based conditions and service-based conditions. The Company recognizes compensation expense related to its restricted stock and deferred stock awards ratably over the corresponding vesting periods. During the three months ended March 31, 2019, the Company granted 977,745 shares of restricted stock to its employees and non-employee directors under the Amended and Restated 2008 Incentive Plan. At March 31, 2019, the Company had 53,779 shares available for future grants and awards under its Amended and Restated 2008 Incentive Plan. On March 20, 2019, the Company’s Board of Directors amended and restated the Amended and Restated 2008 Incentive Plan, subject to shareholder approval, to, among other things, increase the number of shares of the Company’s common stock available for issuance under the Amended and Restated 2008 Incentive Plan by 8,275,000 shares. Under the Company’s 1996 Non-Qualified Employee Stock Purchase Plan, as amended (the “ESPP”), employees are permitted to purchase the Company’s common stock at 85% of market value on January 1st, April 1st, July 1st and October 1st of each year. Under the Company’s 2015 Non-Qualified Stock Purchase Plan (the “SPP”), certain eligible non-employee service providers are permitted to purchase the Company’s common stock at 90% of market value on January 1st, April 1st, July 1st and October 1st of each year. Each of the ESPP and the SPP provide for the issuance of an aggregate of 2.6 million shares of the Company’s common stock less the number of shares of common stock purchased under the other plan. The Company recognizes stock-based compensation expense for the discount received by participating employees and non-employee service providers. During the three months ended March 31, 2019, 99,866 shares in aggregate were issued under the ESPP and SPP. At March 31, 2019, the Company had approximately 1.5 million shares in aggregate reserved for issuance under the ESPP and SPP. During the three months ended March 31, 2019 and 2018, the Company recognized stock-based compensation expense of $11.0 million and $9.7 million, respectively. |

Common Stock Repurchase Programs |

| Common Stock Repurchase Programs |
In July 2013, the Company’s Board of Directors authorized the repurchase of shares of the Company’s common stock up to an amount sufficient to offset the dilutive impact from the issuance of shares under the Company’s equity compensation programs. The share repurchase program allows the Company to make open market purchases from time-to-time based on general economic and market conditions and trading restrictions. The repurchase program also allows for the repurchase of shares of the Company’s common stock to offset the dilutive impact from the issuance of shares, if any, related to the Company’s acquisition program. No shares were purchased under this program during the three months ended March 31, 2019. In August 2018, the Company announced that its Board of Directors had authorized the repurchase of up to $500.0 million of the Company’s common stock in addition to its existing share repurchase program, of which $250.0 million remained available for repurchase as of December 31, 2018. Under this program, during the three months ended March 31, 2019, the Company repurchased approximately 2.5 million shares of its common stock for $78.6 million. The Company also withheld 19,331 shares to satisfy minimum statutory withholding obligations of $0.6 million in connection with the vesting of restricted stock during the quarter. Subsequent to the end of the first quarter of 2019, the Company repurchased an additional 817,950 shares of its common stock for $21.4 million. The Company intends to utilize various methods to effect any future share repurchases, including, among others, open market purchases and accelerated share repurchase programs. The amount and timing of repurchases will depend upon several factors, including general economic and market conditions and trading restrictions. |

| Commitments and Contingencies Disclosure [Abstract] | |||||
| Commitments and Contingencies |
The Company expects that audits, inquiries and investigations from government authorities and agencies will occur in the ordinary course of business. Such audits, inquiries and investigations and their ultimate resolutions, individually or in the aggregate, could have a material adverse effect on the Company’s business, financial condition, results of o perations, cash flows and the trading price of its securities. The Company has not included an accrual for these matters as of March 31, 2019 in its Condensed Consolidated Financial Statements, as the variables affecting any potential eventual liability depend on the currently unknown facts and circumstances that arise out of, and are specific to, any particular future audit, inquiry and investigation and cannot be reasonably estimated at this time. In the ordinary course of business, the Company becomes involved in pending and threatened legal actions and proceedings, most of which involve claims of medical malpractice related to medical services provided by the Company’s affiliated physicians. The Company’s contracts with hospitals generally require the Company to indemnify them and their affiliates for losses resulting from the negligence of the Company’s affiliated physicians. The Company may also become subject to other lawsuits which could involve large claims and significant costs. The Company believes, based upon a review of pending actions and proceedings, that the outcome of such legal actions and proceedings will not have a material adverse effect on its business, financial condition, results of operations, cash flows and the trading price of its securities. 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 the Company’s business, financial condition, results of operations, cash flows and the trading price of its securities. Although the Company currently maintains liability insurance coverage intended to cover professional liability and certain other claims, the Company cannot assure that its insurance coverage will be adequate to cover liabilities arising out of claims asserted against it in the future where the outcomes of such claims are unfavorable. With respect to professional liability risk, the Company generally self-insures a portion of this risk through its wholly owned captive insurance subsidiary. Liabilities in excess of the Company’s insurance coverage, including coverage for professional liability and certain other claims, could have a material adverse effect on the Company’s business, financial condition, results of operations, cash flows and the trading price of its securities. |

This guidance became effective for the Company on January 1, 2019. The adoption of this guidance had a material impact on the Company’s Consolidated Balance Sheets and related disclosures, resulting from the recognition of significant right of use assets and related liabilities, primarily related to its operating lease arrangements for space in hospitals and certain other facilities for its business and medical offices.

Generally, only investments with original maturities of three months or less qualify as cash equivalents by definition. Original maturity means an original maturity to the entity holding the investment. For example, both a three-month US Treasury bill and a three-year Treasury note purchased three months from maturity qualify as cash equivalents. However, a Treasury note purchased three-years ago does not become a cash equivalent when its remaining maturity is three months. No definition available.

- Definition Investments in debt and equity securities which are categorized neither as held-to-maturity nor trading and which are intended to be sold or mature more than one year from the balance sheet date or operating cycle, if longer. Such securities are reported at fair value; unrealized gains (losses) related to Available-for-sale Securities are excluded from earnings and reported in a separate component of shareholders' equity (other comprehensive income), unless the Available-for-sale security is designated as a hedge or is determined to have had an other than temporary decline in fair value below its amortized cost basis. All or a portion of the unrealized holding gain (loss) of an Available-for-sale security that is designated as being hedged in a fair value hedge is recognized in earnings during the period of the hedge, as are other than temporary declines in fair value below the cost basis for investments in equity securities and debt securities that an entity intends to sell or it is more likely than not that it will be required to sell before the recovery of its amortized cost basis. Other than temporary declines in fair value below the cost basis for debt securities categorized as Available-for-sale that an entity does not intend to sell and for which it is not more likely than not that the entity will be required to sell before the recovery of its amortized cost basis are bifurcated into credit losses and losses related to all other factors. Other than temporary declines in fair value below cost basis related to credit losses are recognized in earnings, and losses related to all other factors are recognized in other comprehensive income.
