Accounting Policies [Abstract]
Basis of Presentation	Basis of Presentation The financial statements include the unaudited condensed consolidated balance sheets, income statements, comprehensive income statements, statements of cash flows and statements of changes in equity of the Company and its affiliates, which are controlled by the Company through the Company's direct or indirect ownership of a majority equity interest and rights granted to the Company through certain variable interests. All intercompany balances and transactions have been eliminated in consolidation. In the opinion of management, all adjustments, which consist of normal recurring adjustments, and disclosures considered necessary for a fair presentation have been included. The accompanying unaudited 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 Rule 10-01 of Regulation S-X. Certain information and disclosures normally included in annual financial statements presented in accordance with GAAP have been omitted in these interim financial statements pursuant to rules and regulations of the Securities and Exchange Commission ("SEC"). Accordingly, these unaudited condensed consolidated financial statements and related notes should be read in conjunction with the Company's audited consolidated financial statements and notes thereto included in the Company's Annual Report on Form 10-K for the year ended December 31, 2025 (the "Annual Report").
Adoption of Recently Issued Accounting Standards, and Recent Accounting Pronouncements Not Yet Adopted	Recent Accounting Pronouncements Not Yet Adopted In November 2024, the Financial Accounting Standards Board (the "FASB") issued Accounting Standards Update ("ASU") 2024-03, Disaggregation of Income Statement Expenses ("ASU 2024-03"), which requires the disclosure of certain disaggregated expenses within the notes to the financial statements. ASU 2024-03 is effective for annual periods beginning after December 15, 2026, and interim reporting periods within fiscal years beginning after December 15, 2027. Adoption of ASU 2024-03 can either be applied prospectively to consolidated financial statements issued for reporting periods after the effective date of this standard or retrospectively to any or all prior periods presented in the consolidated financial statements. Early adoption is also permitted. The Company is currently evaluating the standard to determine its impact on the Company’s disclosures. In September 2025, the FASB issued ASU 2025-06, Intangibles - Goodwill and Other - Internal-Use Software (Topic 350): Targeted Improvements to the Accounting for Internal-Use Software ("ASU 2025-06"), which modernizes the current internal-use software accounting guidance by removing all references to software project development stages. Under ASU 2025-06, an entity begins capitalizing software costs when (i) management has implicitly or explicitly authorized and committed to funding a computer software project and (ii) it is probable the project will be completed and the software will be used to perform the function intended (referred to as the "probable-to-complete recognition threshold"). This ASU is effective for annual reporting periods beginning after December 15, 2027, and interim periods within those annual reporting periods, with early adoption permitted. The Company is currently evaluating the standard to determine its impact on the Company's disclosures.
Variable interest entities	Variable Interest Entities Variable interest entities ("VIEs") must be consolidated if an entity’s interest in the VIE is a controlling financial interest. Under the variable interest model, a controlling financial interest is determined based on which entity, if any, has (i) the power to direct the activities of the VIE that most significantly impact the VIE’s economic performance and (ii) the obligation to absorb the losses, or the right to receive the benefits, from the VIE that could potentially be significant to the VIE. The Company performs ongoing reassessments of whether changes in the facts and circumstances regarding the Company's involvement with a VIE could cause the Company’s consolidation conclusion to change. The consolidation status of the VIEs with which the Company is involved may change as a result of such reassessments. Changes in consolidation status are applied prospectively. The Company, through its wholly-owned subsidiaries, owns majority interests in certain limited liability companies ("LLCs"), with each LLC owning and operating one or more hospitals. The noncontrolling interest is typically owned by a not-for-profit medical system, university, academic medical center or foundation or combination thereof (individually or collectively referred to as "minority member"). The employees that work for the LLC and the related hospital(s) are employees of the Company, and the Company manages the day-to-day operations of the LLC and the hospital(s) pursuant to a management services agreement ("MSA"). The LLCs are VIEs due to their structure as LLCs and the control that resides with the Company through the MSA. The Company consolidates each of these LLCs as it is considered the primary beneficiary due to the MSA providing the Company the right to direct the day-to-day operating and capital activities of the LLC and the respective hospital(s) that most significantly impact the LLC’s economic performance. Additionally, the Company would absorb a majority of the entity's expected losses, receive a majority of the entity's expected residual returns, or both, as a result of its majority ownership, contractual or other financial interests in the entity. The MSAs are subject to termination only by mutual agreement of the Company and minority member, except in the case of gross negligence, fraud or bankruptcy of the Company, in which case the minority member can force termination of the MSA. All of the Company's VIEs meet the definition of a business, and the Company holds a majority of their issued voting equity interests. Their assets are not required to be used only for the settlement of VIE obligations as the Company has the ability to direct the use of the VIE assets through its joint venture and cash management agreements.
Accounting estimates	Accounting Estimates The preparation of financial statements in conformity with GAAP requires management to make estimates and judgments that affect the amounts reported in the unaudited condensed consolidated financial statements and accompanying notes. On an ongoing basis, the Company evaluates its estimates. The Company bases its estimates on historical experience and on various other assumptions that are believed to be reasonable under the circumstances, the results of which form the basis for making judgments about the carrying values of assets and liabilities that are not readily apparent from other sources. Actual results may differ from these estimates.
Revenue recognition	Revenue Recognition Overview The Company's revenue generally relates to contracts with patients in which its performance obligations are to provide healthcare services to the patients. Revenue is recorded during the period the Company's obligations to provide healthcare services are satisfied. Revenue for performance obligations satisfied over time is recognized based on charges incurred in relation to total expected charges. The Company's performance obligations for inpatient services are generally satisfied over periods that average approximately five days. The Company's performance obligations for outpatient services are generally satisfied over a period of less than one day. As the Company's performance obligations relate to contracts with a duration of one year or less, the Company elected the optional exemption and, therefore, is not required to disclose the transaction price for the remaining performance obligations at the end of the reporting period or when the Company expects to recognize revenue. Additionally, the Company is not required to adjust the consideration for the existence of a significant financing component when the period between the transfer of the services and the payment for such services is one year or less. Contractual Adjustments, Discounts and Cost Report Settlements Contractual relationships with patients, in most cases, involve a third party payor (Medicare, Medicaid and managed care health plans), and the transaction prices for services provided are dependent upon the terms provided by (Medicare and Medicaid) or negotiated with (managed care health plans) 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's revenue is based upon the estimated amounts the Company expects to be entitled to receive from patients and third party payors. Estimates of contractual adjustments under managed care insurance plans are based upon the contractual payment terms specified in the related contractual agreements and the historical collection experience of each payor. Revenue related to uninsured patients and copayment and deductible amounts for patients who have healthcare coverage may have discounts applied (uninsured discounts and other discounts). The Company also records estimated implicit price concessions (based primarily on historical collection experience) related to uninsured accounts to record self-pay revenue at the estimated amounts expected to be collected. Medicare and Medicaid regulations and various managed care contracts, under which the discounts from the Company's standard charges must be calculated, are complex and are subject to interpretation and adjustment. The Company estimates contractual adjustments on a payor-specific basis based on its interpretation of the applicable regulations or contract terms and the historical collection experience of each payor. However, the necessity of the services authorized and provided, and resulting reimbursements, are often subject to interpretation. These interpretations may result in payments that differ from the Company's estimates. Additionally, updated regulations and contract renegotiations occur frequently, necessitating continual review and assessment of the estimates by management. Due to the complexities involved in the classification and documentation of healthcare services under the laws and regulations governing Medicare and Medicaid programs, the Company's estimates of revenue earned and related reimbursement are often subject to interpretation that could result in payments that are different from its estimates. Final determination of amounts earned under Medicare, Medicaid and other third party payor programs often occurs in subsequent years because of audits by the programs, rights of appeal, and the application of technical provisions. Estimated reimbursement amounts, which are recorded within net patient service revenue in the period in which the related services are rendered, are adjusted in subsequent periods as determined (in relation to certain government programs, primarily Medicare, this is generally referred to as the "cost report" filing and settlement process). Differences between original estimates and subsequent revisions, including final settlements, are recorded as adjustments to net patient service revenue in the period in which such revisions become known.
Acquisitions	Acquisitions Acquisitions are accounted for using the acquisition method of accounting and the results of operations are included in the unaudited condensed consolidated income statement from the respective dates of acquisition. The purchase price of these transactions is allocated to the assets acquired and liabilities assumed based upon their respective fair values at the date of acquisition and can be subject to change up to 12 months subsequent to the acquisition date due to settling amounts related to purchased working capital and final determination of fair value estimates.
Investments in Equity Securities	Investments in Equity Securities The Company holds an option to acquire equity securities of a privately held company (the “Investment”), and the Investment does not have a readily determinable fair value. The Company has elected to account for the Investment using the measurement alternative. Under the measurement alternative, an investment is recorded at cost, less impairment, if any, and adjusted for observable price changes in orderly transactions involving identical or similar equity securities of the same issuer. The Investment is not measured at fair value on a recurring basis.
Fair value of financial instruments	Fair Value of Financial Instruments Cash and cash equivalents, accounts receivable, inventories, prepaid expenses, other current assets, accounts payable, accrued salaries and benefits, accrued interest and other accrued expenses and current liabilities (other than those pertaining to lease liabilities) are reflected in the accompanying unaudited condensed consolidated financial statements at amounts that approximate fair value because of the short-term nature of these instruments. The fair value of the Company’s revolving credit facility also approximates its carrying value as it bears interest at current market rates. Refer to Note 5, Interest Rate Swap Agreements, for discussion of the fair value measurement of the Company’s derivative instruments.
Noncontrolling interests	Noncontrolling Interests The financial statements include the financial position and results of operations of hospital and healthcare operations in which the Company owned less than 100% of the equity interests, but maintained a controlling interest during the presented periods. Earnings or losses attributable to the noncontrolling interests are presented separately in the consolidated income statements. Holders of noncontrolling interests are considered to be equity holders in the consolidated company, pursuant to which noncontrolling interests are classified as part of equity, unless the noncontrolling interests are redeemable. Certain redemptive features associated with the noncontrolling interests for The University of Kansas Health System – St. Francis Campus ("St. Francis") could require the Company to deliver cash if the redemptive features are exercised. These redemptive features could be exercised upon, among other things, the Company’s exclusion or suspension from participation in any federal or state government healthcare payor program. Therefore, the noncontrolling interests balance for St. Francis is classified outside the permanent equity section of the Company’s unaudited condensed consolidated balance sheets. The redeemable noncontrolling interests related to St. Francis at March 31, 2026 and December 31, 2025 have not been subsequently measured at fair value since the acquisition date in 2017. The noncontrolling interests are not currently redeemable and it is not probable that the noncontrolling interests will become redeemable as the possibility of the Company being excluded or suspended from participation in any federal or state government healthcare payor program is remote.
Earnings per share	Earnings Per Share Basic net income per share is computed by dividing net income available to common stockholders by the weighted-average common shares outstanding during the period. Diluted net income per share takes into account the potential dilution that could occur if securities or other contracts to issue shares, such as unvested restricted stock units, were exercised and converted into shares. Diluted net income per share is computed by dividing net income available to common stockholders by the weighted-average common shares outstanding during the period, increased by the number of additional shares that would have been outstanding if the potential shares had been issued and were dilutive.
