Acquisition [Abstract]
Acquisition	Acquisition On January 16, 2014, the Company acquired 100 percent of the voting interests of Coram LLC ("Coram"), the specialty infusion services and enteral nutrition business unit of Apria Healthcare Group Inc. for cash consideration of approximately $2.1 billion, plus contingent consideration of approximately $0.1 billion. The purchase price is also subject to a working capital adjustment. Coram is one of the nation's largest providers of comprehensive infusion services, caring for approximately 165,000 patients annually. Coram has approximately 4,600 employees, including approximately 600 nurses and 250 dietitians, operating primarily through 84 branch locations and six centers of excellence for patient intake. The contingent consideration is based on the Company’s future realization of Coram’s tax net operating loss carryforwards (“NOLs”) as of the date of the acquisition. The Company will pay the seller the first $60 million in tax savings realized from the future utilization of the Coram NOLs, plus 50% of any additional future tax savings from the remaining NOLs. The estimated fair value of the approximately $0.1 billion contingent consideration liability associated with the future realization of the Coram NOLs was estimated by discounting, to present value, the contingent payments expected to be made based on the Company’s estimate of the amount and timing of Coram NOLs that will ultimately be realized. The fair value of assets acquired and liabilities assumed were approximately $2.5 billion and $0.3 billion, respectively, which included accounts receivable of approximately $0.2 billion, identifiable finite-lived intangible assets of approximately $0.5 billion and goodwill of approximately $1.6 billion which is nondeductible for income tax purposes. The goodwill represents future economic benefits expected to arise from the Company's expanded presence in the specialty pharmaceuticals market, the assembled workforce acquired, and the expected synergies from combining operations with Coram. The assessment of fair value is preliminary and is based on information that was available to management at the time the condensed consolidated financial statements were prepared. Accordingly, such amounts may change. The most significant open items include the working capital adjustment, the accounting for deferred income taxes including the acquired NOLs, and the accounting for the related contingent consideration liability. The Company has requested additional information from the seller with respect to certain acquired tax attributes and uncertain tax positions and is awaiting the completion of a third party study to quantify the Company's annual NOL usage limitation. Coram’s results of operations are included in the Company’s Pharmacy Services Segment beginning on January 16, 2014. Pro forma information for this acquisition is not presented as Coram’s results are immaterial to the Company’s condensed consolidated financial statements. During the three months ended March 31, 2014, acquisition costs of $14 million were expensed as incurred within operating expenses.
