Accounting Policies [Abstract]
Recently Adopted Accounting Pronouncements	Recently Adopted Accounting Pronouncements In March 2016, the accounting guidance related to various aspects of share-based payment transactions was amended, including income tax consequences, classification of awards as either equity or liabilities, and classification on the statement of cash flows. Under the new guidance, excess tax benefits and deficiencies are to be recognized as income tax benefits or expenses in the income statement as discrete items in the reporting period in which they occur instead of increases or decreases to shareholders’ equity. Excess tax benefits should be classified along with other income tax cash flows as operating activities. With regard to forfeitures, the entity may make an entity-wide accounting policy election to either estimate the number of awards that are expected to vest or account for forfeitures when they occur. This guidance became effective for the Company on January 1, 2017. The Company adopted this guidance prospectively for both the income statement and statement of cash flows, and the adoption of this guidance did not have a material impact on the Company’s Consolidated Financial Statements. The Company continues to estimate forfeitures based on the number of awards that are expected to vest.
New Accounting Pronouncements	New Accounting Pronouncements In January 2017, the accounting guidance related to goodwill impairment was amended to remove step two of the impairment test that requires a hypothetical purchase price allocation in order to measure the amount of any impairment. Under the new guidance, only a single-step quantitative test is required and any goodwill impairment will now be the amount by which a reporting unit’s carrying value exceeds its fair value. The new guidance does not amend the optional alternative to perform a qualitative assessment to determine if a quantitative goodwill impairment test is necessary. This guidance will become effective for the Company on January 1, 2020, with early adoption permitted. The Company does not believe the adoption of this guidance will have an impact on its Consolidated Financial Statements. In January 2017, the accounting guidance related to business combinations was amended to clarify the definition of a business. This guidance will become effective for the Company on January 1, 2018, with early adoption permitted. The Company does not believe the adoption of this guidance will have an impact on its Consolidated Financial Statements. In August 2016, the accounting guidance related to the statement of cash flows was amended with the intent of reducing diversity in practice as to the classification of certain transactions in the statement of cash flows. This guidance will become effective for the Company on January 1, 2018, with early adoption permitted. The Company does not believe the adoption of this guidance will have a material impact on its Consolidated Financial Statements. In February 2016, accounting guidance related to leases was issued that will 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 will become effective for the Company on January 1, 2019, with early adoption permitted. The Company expects that the adoption of this guidance will have a material impact on its 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. The Company’s evaluation of this guidance and its impacts will continue throughout 2017. In May 2014, the accounting guidance related to revenue recognition was amended to outline a single, comprehensive model for accounting for revenue from contracts with customers. The new guidance will become effective for the Company on January 1, 2018. The Company’s current revenue recognition policies for its significant revenue streams materially comply with the amended guidance; therefore, the Company does not believe the adoption of this guidance will have a material impact on its Consolidated Financial Statements. The Company’s evaluation of the impact the adoption of this guidance will have on its Consolidated Financial Statements will continue through the third quarter of 2017.
