Leases [Abstract]
Leases	Lease Accounting In April 2017, in conjunction with the implementation of a new “go-to-market” business model for the Company's U.S. dispensing business within the Medication Management Solutions (“MMS”) unit of the Medical segment, the Company amended the terms of certain customer leases for dispensing equipment within the MMS unit. The modification provided customers the ability to reduce its dispensing asset base via a return provision, resulting in a more flexible lease term. Prior to the modification, these leases were accounted for as sales-type leases in accordance with Accounting Standards Codification Topic 840, "Leases", as the non-cancellable lease term of five years exceeded 75% of the equipment’s estimated useful life and the present value of the minimum lease payments exceeded 90% of the equipment’s fair value. As a result of the lease modification, the Company was required to reassess the classification of the leases due to the amended lease term. Accordingly, most amended lease contracts were classified as operating leases beginning in April 2017. The change in lease classification resulted in a pre-tax charge to earnings in the third quarter of fiscal year 2017 of $741 million, which was recorded in Other operating (income) expense, net, relating to the derecognition of the net investment in sales-type leases of $1.057 billion, partially offset by the recognition of the underlying leased assets, as Property, Plant and Equipment on the Company’s balance sheet, as of the effective date of $316 million. Beginning April 1, 2017, revenue associated with these modified contracts is recognized on a straight-line basis over the remaining lease term, along with depreciation on the reinstated leased assets.

In April 2017, in conjunction with the implementation of a new “go-to-market” business model for the Company's U.S. dispensing business within the Medication Management Solutions (“MMS”) unit of the Medical segment, the Company amended the terms of certain customer leases for dispensing equipment within the MMS unit.
