Goodwill and Intangible Asset Impairment [Abstract]
Goodwill, Policy	Goodwill is allocated to each identified reporting unit, which is defined as an operating segment or one level below the operating segment (referred to as a component of the entity). Management has determined that the Company’s operating segments meet the criteria to be classified as reporting units. During the three months ended June 30, 2016, the Company allocated approximately $709 million of goodwill to the spin-off of QHC, including approximately $33 million of goodwill related to the former management services reporting unit and approximately $676 million of goodwill allocated from the hospital operations reporting unit based on a relative fair value calculation of the hospitals that were included in the QHC distribution. At June 30, 2016, after giving effect to the disposition of QHC and the $1.4 billion impairment charge discussed below, the hospital operations reporting unit and the home care agency operations reporting unit had approximately $6.9 billion and $47 million, respectively, of goodwill. Goodwill is evaluated for impairment at the same time every year and when an event occurs or circumstances change that, more likely than not, reduce the fair value of the reporting unit below its carrying value. There is a two-step method for determining goodwill impairment. Step one is to compare the fair value of the reporting unit with the unit’s carrying amount, including goodwill. If this test indicates the fair value is less than the carrying value, then step two is required to compare the implied fair value of the reporting unit’s goodwill utilizing a hypothetical purchase price allocation with the carrying value of the reporting unit’s goodwill. The Company performed its last annual goodwill evaluation as of September 30, 2015. No impairment was indicated by this evaluation. The next annual goodwill evaluation will be performed as of September 30, 2016. The Company estimates the fair value of the related reporting units using both a discounted cash flow model as well as a market multiple model. The cash flow forecasts are adjusted by an appropriate discount rate based on the Company’s estimate of a market participant’s weighted-average cost of capital. These models are both based on the Company’s best estimate of future revenues and operating costs and are reconciled to the Company’s consolidated market capitalization, with consideration of the amount a potential acquirer would be required to pay, in the form of a control premium, in order to gain sufficient ownership to set policies, direct operations and control management decisions.
