Organization, Consolidation and Presentation of Financial Statements [Abstract]
Basis of Presentation	Basis of Presentation The accompanying condensed consolidated financial statements have been prepared in accordance with U.S. generally accepted accounting principles ("GAAP") for interim financial information and with the instructions to Form 10-Q and Article 10 of Regulation S-X. Accordingly, they do not include all of the information and notes required by GAAP for complete financial statements. In the opinion of management, all adjustments (consisting of normal recurring adjustments) considered necessary for fair presentation of the Company's financial position and results of operations have been included. The Company’s fiscal year ends on December 31 and interim results are not necessarily indicative of results for a full year or any other interim period. The information contained in these condensed consolidated financial statements should be read in conjunction with the Company’s consolidated financial statements and notes thereto included in the Company's Annual Report on Form 10-K for the year ended December 31, 2023 (the "2023 Annual Report on Form 10-K").
Reclassification	Certain prior year amounts have been reclassified to conform with the current year presentation.
Principles of Consolidation	The condensed consolidated financial statements include the accounts of the Company and its wholly-owned subsidiaries, as well as interests in partnerships and limited liability companies controlled by the Company through its ownership of a majority voting interest or other rights granted to the Company by contract to manage and control the affiliate's business. All significant intercompany balances and transactions are eliminated in consolidation.
Use of Estimates	Use of Estimates The preparation of financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the amounts reported in the condensed consolidated financial statements and footnotes. Examples include, but are not limited to, estimates of accounts receivable allowances, professional and general liabilities and the estimate of deferred tax assets or liabilities. Actual results could differ from those estimates.
Revenues	Revenues The Company's revenues generally relate to contracts with patients in which the performance obligations are to provide health care services. The Company recognizes revenues in the period in which its obligations to provide health care services are satisfied and reports the amount that reflects the consideration the Company expects to be entitled to receive. The contractual relationships with patients, in most cases, also involve a third-party payor (e.g., Medicare, Medicaid and private insurance organizations, including plans offered through the health insurance exchanges) and the transaction prices for the services provided are dependent upon the terms provided by or negotiated with the third-party payors. The payment arrangements with third-party payors for the services provided to the related patients typically specify payments at amounts less than the Company's standard charges. The Company continually reviews the contractual estimation process to consider and incorporate updates to laws and regulations and the frequent changes in managed care contractual terms resulting from contract renegotiations and renewals. Patient service revenues. This revenue is related to charging facility fees in exchange for providing patient care. The fee charged for health care procedures performed in surgical facilities varies depending on the type of service provided, but usually includes all charges for usage of an operating room, a recovery room, special equipment, medical supplies, nursing staff and medications. The fee does not normally include professional fees charged by the patient’s surgeon, anesthesiologist or other attending physician, which are billed directly by such physicians to the patient or third-party payor. However, in several surgical facilities, the Company charges for anesthesia services. Ancillary service revenues include fees for patient visits to the Company's physician practices, pharmacy services and diagnostic tests ordered by physicians. Patient service revenues are recognized as performance obligations are satisfied. Performance obligations are based on the nature of services provided. Typically, the Company recognizes revenue at a point in time in which services are rendered and the Company has no obligation to provide further patient services. Because the Company primarily performs outpatient procedures, performance obligations are generally satisfied same day and revenue is recognized on the date of service. The Company determines the transaction price based on gross charges for services provided, net of estimated contractual adjustments and discounts from third-party payors. The Company estimates its contractual adjustments and discounts based on contractual agreements, its discount policies and historical experience. Changes in estimated contractual adjustments and discounts are recorded in the period of change. Several states utilize supplemental Medicaid reimbursement programs for the purpose of providing reimbursement to providers to increase base rates to the levels that Medicare would have paid for the same service or for payments that offset a portion of the cost of providing care to Medicaid and indigent patients. These programs are designed with input from the Centers for Medicare & Medicaid Services (“CMS”) and are funded with a combination of state and federal resources, including, in certain instances, fees or taxes levied on the providers. We account for payments under these supplemental programs as variable consideration and estimate the amount using the most likely amount method. Reimbursement under these programs, including the recognition of variable consideration, is reflected in patient service revenues. Taxes or other program-related costs are reflected in other operating expenses. Other service revenues. Other service revenues include management and administrative service fees derived from the non-consolidated facilities that the Company accounts for under the equity method, management of surgical facilities in which it does not own an interest, and management services provided to physician practices for which the Company is not required to provide capital or additional assets and other non-patient services. The management agreements typically require the Company to provide recurring management services over a multi-year period, which are billed and collected on a monthly basis. The fees derived from these management arrangements are based on a predetermined percentage of the revenues of each facility or practice and are recognized in the period in which management services are rendered and billed.
Accounts Receivable	Accounts Receivable Accounts receivable from third-party payors are recorded net of estimated implicit price concessions, which are estimated based on the historical trend of the Company's surgical hospitals’ cash collections and contractual write-offs, and for the Company's surgical facilities in general, established fee schedules, relationships with payors and procedure statistics. While changes in estimated reimbursement from third-party payors remain a possibility, the Company expects that any such changes would be minimal and, therefore, would not have a material effect on its financial condition or results of operations. Accounts receivable consists of receivables from federal and state agencies (under the Medicare and Medicaid programs), private insurance organizations, employers and patients. Management recognizes that revenues and receivables from government agencies are significant to the Company's operations, but it does not believe that there is significant credit risk associated with these government agencies. Concentration of credit risk with respect to other payors is limited because of the large number of such payors. The Company recognizes that final reimbursement of accounts receivable is subject to final approval by each third-party payor. However, because the Company has contracts with its third-party payors and also verifies insurance coverage of the patient before medical services are rendered, the amounts that are pending approval from third-party payors are not considered significant. Amounts are classified outside of self-pay if the Company has an agreement with the third-party payor or has verified a patient’s coverage prior to services rendered. The Company's policy is to collect co-payments and deductibles prior to providing medical services. Patient services of the Company are primarily non-emergency, which allows the surgical facilities to control the procedures for which third-party reimbursement is sought and obtained. The Company does not require collateral from self-pay patients. The Company's collection policies and procedures are based on the type of payor, size of claim and estimated collection percentage for each patient account. The Company analyzes accounts receivable at each of its surgical facilities to ensure the proper collection and aged category. Collection efforts include direct contact with third-party payors or patients, written correspondence and the use of legal or collection agency assistance, as required.
Income Taxes	Income Taxes The Company uses the asset and liability method to account for income taxes. Under this method, deferred income tax assets and liabilities are recognized for the future tax consequences attributable to differences between the financial statement carrying amounts of existing assets and liabilities and their respective tax bases. Deferred tax assets and liabilities are measured using enacted tax rates expected to apply to taxable income in the years in which those temporary differences are expected to be recovered or settled. The effect on deferred tax assets and liabilities of a change in tax rates is recognized in income in the period that includes the enactment date. If a carryforward exists, the Company makes a determination as to whether the carryforward will be utilized in the future. A valuation allowance is established for certain carryforwards when their recoverability is deemed to be uncertain. The carrying value of the net deferred tax assets assumes that the Company will be able to generate sufficient future taxable income in certain tax jurisdictions, based on estimates and assumptions. If our expectations for future operating results on a consolidated basis or at the state jurisdiction level vary from actual results due to changes in health care regulations, general economic conditions, or other factors, we may need to adjust the valuation allowance, for all or a portion of our deferred tax assets. Our income tax expense in future periods will be reduced or increased to the extent of offsetting decreases or increases, respectively, in our valuation allowance in the period when the change in circumstances occurs. These changes could have a significant impact on our future earnings. The Company and certain of its subsidiaries file a consolidated federal income tax return. The partnerships, limited liability companies, and certain non-consolidated physician practice corporations also file separate income tax returns. The Company's allocable portion of each partnership's and limited liability company's income or loss is included in taxable income of the Company. The remaining income or loss of each partnership and limited liability company is allocated to the other owners.
Goodwill	Goodwill Goodwill represents the excess of the fair value of the consideration provided in an acquisition plus the fair value of any non-controlling interests over the fair value of net assets acquired and is not amortized. Additions to goodwill include amounts resulting from new business combinations and incremental ownership purchases in the Company's subsidiaries.
Derivative Instruments and Hedging Activities	Derivative Instruments and Hedging Activities The Company records all derivatives on the balance sheet at fair value and any financing elements treated as debt instruments are recorded at amortized cost. The accounting for changes in the fair value of derivatives depends on the intended use of the derivative, whether the Company has elected to designate a derivative in a hedging relationship and apply hedge accounting and whether the hedging relationship has satisfied the criteria necessary to apply hedge accounting. Hedge accounting generally provides for the matching of the timing of gain or loss recognition on the hedging instrument with the recognition of the changes in the fair value of the hedged asset or liability that are attributable to the hedged risk in a fair value hedge or the earnings effect of the hedged forecasted transactions in a cash flow hedge. The Company may enter into derivative contracts that are intended to economically hedge certain risks, even though hedge accounting does not apply or the Company elects not to apply hedge accounting. The Company made an accounting policy election to measure the credit risk of its derivative financial instruments that are subject to master netting agreements on a net basis by counterparty portfolio.
Non-Controlling Interests—Redeemable	Non-Controlling Interests—Redeemable Each partnership and limited liability company through which the Company owns and operates its surgical facilities is governed by a partnership or operating agreement, respectively. In certain circumstances, the applicable partnership or operating agreements for the Company's surgical facilities provide that the facilities will purchase all of the physician limited partners’ or physician minority members’, as applicable, ownership if certain adverse regulatory events occur, such as it becoming illegal for the physician(s) to own an interest in a surgical facility, refer patients to a surgical facility or receive cash distributions from a surgical facility. Management believes the likelihood of an event occurring that would trigger such purchases was remote as of June 30, 2024. The non-controlling interests—redeemable are reported outside of stockholders' equity in the condensed consolidated balance sheets.
Fair Value of Financial Instruments	Fair Value of Financial Instruments The fair value of a financial instrument is the amount at which the instrument could be exchanged in an orderly transaction between market participants to sell the asset or transfer the liability. The Company uses fair value measurements based on inputs classified into the following hierarchy: •Level 1: Unadjusted quoted prices in active markets for identical assets or liabilities. •Level 2: Inputs other than quoted prices that are observable for the asset or liability, either directly or indirectly. These may include quoted prices for similar assets or liabilities in active markets and quoted prices for identical or similar assets or liabilities in markets that are not active. •Level 3: Unobservable inputs in which little or no market data exists, therefore requiring an entity to develop its own assumptions, depending on the nature of the item being valued. The carrying amounts reported in the condensed consolidated balance sheets for cash and cash equivalents, accounts receivable and accounts payable approximate their fair values under Level 3 calculations. The fair values in the table above were based on Level 2 inputs using quoted prices for identical liabilities in inactive markets. The carrying amounts related to the Company's other long-term debt obligations, including finance lease obligations, approximate their fair values based on Level 3 inputs.
Variable Interest Entities	Variable Interest Entities The condensed consolidated financial statements include the accounts of variable interest entities ("VIE") in which the Company is the primary beneficiary under the provisions of the Financial Accounting Standards Board's ("FASB") Accounting Standards Codification 810, "Consolidation". The Company has the power to direct the activities that most significantly impact a VIE's economic performance. Additionally, the Company would absorb the majority of the expected losses from any of these entities should such expected losses occur.
Recent Accounting Pronouncements	Recent Accounting Pronouncements In November 2023, the FASB issued Accounting Standards Update ("ASU") 2023-07, Segment Reporting (Topic 280), Improvements to Reportable Segment Disclosures, which requires enhanced disclosures of significant segment expenses.

Accordingly, they do not include all of the information and notes required by GAAP for complete financial statements. In the opinion of management, all adjustments (consisting of normal recurring adjustments) considered necessary for fair presentation of the Company's financial position and results of operations have been included. The Company’s fiscal year ends on December 31 and interim results are not necessarily indicative of results for a full year or any other interim period. The information contained in these condensed consolidated financial statements should be read in conjunction with the Company’s consolidated financial statements and notes thereto included in the Company's Annual Report on Form 10-K for the year ended December 31, 2023 (the "2023 Annual Report on Form 10-K").

Reclassification

Certain prior year amounts have been reclassified to conform with the current year presentation.

Principles of Consolidation

The condensed consolidated financial statements include the accounts of the Company and its wholly-owned subsidiaries, as well as interests in partnerships and limited liability companies controlled by the Company through its ownership of a majority voting interest or other rights granted to the Company by contract to manage and control the affiliate's business. All significant intercompany balances and transactions are eliminated in consolidation.

Use of Estimates

The preparation of financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the amounts reported in the condensed consolidated financial statements and footnotes. Examples include, but are not limited to, estimates of accounts receivable allowances, professional and general liabilities and the estimate of deferred tax assets or liabilities. Actual results could differ from those estimates.

Revenues

The Company's revenues generally relate to contracts with patients in which the performance obligations are to provide health care services. The Company recognizes revenues in the period in which its obligations to provide health care services are satisfied and reports the amount that reflects the consideration the Company expects to be entitled to receive. The contractual relationships with patients, in most cases, also involve a third-party payor (e.g., Medicare, Medicaid and private insurance organizations, including plans offered through the health insurance exchanges) and the transaction prices for the services provided are dependent upon the terms provided by or negotiated with the third-party payors. The payment arrangements with third-party payors for the services provided to the related patients typically specify payments at amounts less than the Company's standard charges. The Company continually reviews the contractual estimation process to consider and incorporate updates to laws and regulations and the frequent changes in managed care contractual terms resulting from contract renegotiations and renewals.

Patient service revenues. This revenue is related to charging facility fees in exchange for providing patient care. The fee charged for health care procedures performed in surgical facilities varies depending on the type of service provided, but usually includes all charges for usage of an operating room, a recovery room, special equipment, medical supplies, nursing staff and medications. The fee does not normally include professional fees charged by the patient’s surgeon, anesthesiologist or other attending physician, which are billed directly by such physicians to the patient or third-party payor. However, in several surgical facilities, the Company charges for anesthesia services. Ancillary service revenues include fees for patient visits to the Company's physician practices, pharmacy services and diagnostic tests ordered by physicians.

Patient service revenues are recognized as performance obligations are satisfied. Performance obligations are based on the nature of services provided. Typically, the Company recognizes revenue at a point in time in which services are rendered and the Company has no obligation to provide further patient services. Because the Company primarily performs outpatient procedures, performance obligations are generally satisfied same day and revenue is recognized on the date of service.

The Company determines the transaction price based on gross charges for services provided, net of estimated contractual adjustments and discounts from third-party payors. The Company estimates its contractual adjustments and discounts based on contractual agreements, its discount policies and historical experience. Changes in estimated contractual adjustments and discounts are recorded in the period of change.

Several states utilize supplemental Medicaid reimbursement programs for the purpose of providing reimbursement to providers to increase base rates to the levels that Medicare would have paid for the same service or for payments that offset a portion of the cost of providing care to Medicaid and indigent patients. These programs are designed with input from the Centers for Medicare & Medicaid Services (“CMS”) and are funded with a combination of state and federal resources, including, in certain instances, fees or taxes levied on the providers. We account for payments under these supplemental programs as variable consideration and estimate the amount using the most likely amount method. Reimbursement under these programs, including the recognition of variable consideration, is reflected in patient service revenues. Taxes or other program-related costs are reflected in other operating expenses.

Other service revenues. Other service revenues include management and administrative service fees derived from the non-consolidated facilities that the Company accounts for under the equity method, management of surgical facilities in which it does not own an interest, and management services provided to physician practices for which the Company is not required to provide capital or additional assets and other non-patient services. The management agreements typically require the Company to provide recurring management services over a multi-year period, which are billed and collected on a monthly basis. The fees derived from these management arrangements are based on a predetermined percentage of the revenues of each facility or practice and are recognized in the period in which management services are rendered and billed.

Accounts Receivable

Accounts receivable from third-party payors are recorded net of estimated implicit price concessions, which are estimated based on the historical trend of the Company's surgical hospitals’ cash collections and contractual write-offs, and for the Company's surgical facilities in general, established fee schedules, relationships with payors and procedure statistics. While changes in estimated reimbursement from third-party payors remain a possibility, the Company expects that any such changes would be minimal and, therefore, would not have a material effect on its financial condition or results of operations.

Accounts receivable consists of receivables from federal and state agencies (under the Medicare and Medicaid programs), private insurance organizations, employers and patients. Management recognizes that revenues and receivables from government agencies are significant to the Company's operations, but it does not believe that there is significant credit risk associated with these government agencies. Concentration of credit risk with respect to other payors is limited because of the large number of such payors.

The Company recognizes that final reimbursement of accounts receivable is subject to final approval by each third-party payor. However, because the Company has contracts with its third-party payors and also verifies insurance coverage of the patient before medical services are rendered, the amounts that are pending approval from third-party payors are not considered significant. Amounts are classified outside of self-pay if the Company has an agreement with the third-party payor or has verified a patient’s coverage prior to services rendered. The Company's policy is to collect co-payments and deductibles prior to providing medical services. Patient services of the Company are primarily non-emergency, which allows the surgical facilities to control the procedures for which third-party reimbursement is sought and obtained. The Company does not require collateral from self-pay patients.

The Company's collection policies and procedures are based on the type of payor, size of claim and estimated collection percentage for each patient account. The Company analyzes accounts receivable at each of its surgical facilities to ensure the proper collection and aged category. Collection efforts include direct contact with third-party payors or patients, written correspondence and the use of legal or collection agency assistance, as required.

Income Taxes

The Company uses the asset and liability method to account for income taxes. Under this method, deferred income tax assets and liabilities are recognized for the future tax consequences attributable to differences between the financial statement carrying amounts of existing assets and liabilities and their respective tax bases. Deferred tax assets and liabilities are measured using enacted tax rates expected

to apply to taxable income in the years in which those temporary differences are expected to be recovered or settled. The effect on deferred tax assets and liabilities of a change in tax rates is recognized in income in the period that includes the enactment date. If a carryforward exists, the Company makes a determination as to whether the carryforward will be utilized in the future. A valuation allowance is established for certain carryforwards when their recoverability is deemed to be uncertain. The carrying value of the net deferred tax assets assumes that the Company will be able to generate sufficient future taxable income in certain tax jurisdictions, based on estimates and assumptions. If our expectations for future operating results on a consolidated basis or at the state jurisdiction level vary from actual results due to changes in health care regulations, general economic conditions, or other factors, we may need to adjust the valuation allowance, for all or a portion of our deferred tax assets. Our income tax expense in future periods will be reduced or increased to the extent of offsetting decreases or increases, respectively, in our valuation allowance in the period when the change in circumstances occurs. These changes could have a significant impact on our future earnings.

The Company and certain of its subsidiaries file a consolidated federal income tax return. The partnerships, limited liability companies, and certain non-consolidated physician practice corporations also file separate income tax returns. The Company's allocable portion of each partnership's and limited liability company's income or loss is included in taxable income of the Company. The remaining income or loss of each partnership and limited liability company is allocated to the other owners.

Goodwill

Goodwill represents the excess of the fair value of the consideration provided in an acquisition plus the fair value of any non-controlling interests over the fair value of net assets acquired and is not amortized. Additions to goodwill include amounts resulting from new business combinations and incremental ownership purchases in the Company's subsidiaries.

Derivative Instruments and Hedging Activities

The Company records all derivatives on the balance sheet at fair value and any financing elements treated as debt instruments are recorded at amortized cost. The accounting for changes in the fair value of derivatives depends on the intended use of the derivative, whether the Company has elected to designate a derivative in a hedging relationship and apply hedge accounting and whether the hedging relationship has satisfied the criteria necessary to apply hedge accounting. Hedge accounting generally provides for the matching of the timing of gain or loss recognition on the hedging instrument with the recognition of the changes in the fair value of the hedged asset or liability that are attributable to the hedged risk in a fair value hedge or the earnings effect of the hedged forecasted transactions in a cash flow hedge. The Company may enter into derivative contracts that are intended to economically hedge certain risks, even though hedge accounting does not apply or the Company elects not to apply hedge accounting.

The Company made an accounting policy election to measure the credit risk of its derivative financial instruments that are subject to master netting agreements on a net basis by counterparty portfolio.

Non-Controlling Interests—Redeemable

Each partnership and limited liability company through which the Company owns and operates its surgical facilities is governed by a partnership or operating agreement, respectively. In certain circumstances, the applicable partnership or operating agreements for the Company's surgical facilities provide that the facilities will purchase all of the physician limited partners’ or physician minority members’, as applicable, ownership if certain adverse regulatory events occur, such as it becoming illegal for the physician(s) to own an interest in a surgical facility, refer patients to a surgical facility or receive cash distributions from a surgical facility. Management believes the likelihood of an event occurring that would trigger such purchases was remote as of June 30, 2024. The non-controlling interests—redeemable are reported outside of stockholders' equity in the condensed consolidated balance sheets.

Fair Value of Financial Instruments

The fair value of a financial instrument is the amount at which the instrument could be exchanged in an orderly transaction between market participants to sell the asset or transfer the liability. The Company uses fair value measurements based on inputs classified into the following hierarchy:

•Level 1: Unadjusted quoted prices in active markets for identical assets or liabilities.

•Level 2: Inputs other than quoted prices that are observable for the asset or liability, either directly or indirectly. These may include quoted prices for similar assets or liabilities in active markets and quoted prices for identical or similar assets or liabilities in markets that are not active.

•Level 3: Unobservable inputs in which little or no market data exists, therefore requiring an entity to develop its own assumptions, depending on the nature of the item being valued.

The carrying amounts reported in the condensed consolidated balance sheets for cash and cash equivalents, accounts receivable and accounts payable approximate their fair values under Level 3 calculations.

The fair values in the table above were based on Level 2 inputs using quoted prices for identical liabilities in inactive markets. The carrying amounts related to the Company's other long-term debt obligations, including finance lease obligations, approximate their fair values based on Level 3 inputs.

Variable Interest Entities

The condensed consolidated financial statements include the accounts of variable interest entities ("VIE") in which the Company is the primary beneficiary under the provisions of the Financial Accounting Standards Board's ("FASB") Accounting Standards Codification 810, "Consolidation". The Company has the power to direct the activities that most significantly impact a VIE's economic performance. Additionally, the Company would absorb the majority of the expected losses from any of these entities should such expected losses occur.

Recent Accounting Pronouncements

In November 2023, the FASB issued Accounting Standards Update ("ASU") 2023-07, Segment Reporting (Topic 280), Improvements to Reportable Segment Disclosures, which requires enhanced disclosures of significant segment expenses. The ASU is effective for annual periods beginning after December 15, 2023 and interim periods beginning after December 15, 2024. The amendments in this ASU must be applied retrospectively to all periods presented and early adoption is permitted. The Company is evaluating the impact of this ASU on its condensed consolidated financial statements.

Leases

LeasesThe Company's operating leases are primarily for real estate, including medical office buildings, and corporate and other administrative offices. The Company's finance leases are primarily for medical equipment and information technology and telecommunications assets.

Earnings Per Share

Earnings Per ShareBasic and diluted earnings (loss) per share are calculated based on the weighted-average number of shares outstanding in each period and dilutive stock options, unvested shares and warrants, to the extent such securities exist and have a dilutive effect on earnings per share.
