Accounting Policies [Abstract]
Use of Estimates	Use of Estimates - The accompanying unaudited condensed consolidated financial statements are prepared in conformity with GAAP, which requires us to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of revenues and expenses during the reporting period. We have made our best estimates, as appropriate under GAAP, in the recognition of our assets and liabilities. These estimates have considered the impact the COVID-19 pandemic may have on our financial position, results of operations and cash flows. Such estimates included, but were not limited to, variable consideration to our customers, our allowance for doubtful accounts for expected credit losses, the net realizable value of our inventory, the fair value of our goodwill and the recoverability of other long-lived assets. Actual results could differ materially from these estimates.
Accounting Pronouncements Recently Adopted	Accounting Pronouncements Recently Adopted In June 2016, the Financial Accounting Standards Board (“FASB”) issued Accounting Standard Update (“ASU”) 2016-13, Financial Instruments – Credit Losses (Topic 326). The new guidance describes the current expected credit loss (“CECL”) model which requires an estimate of expected impairment on financial instruments over the lifetime of the assets at each reporting date. Financial instruments in scope of the guidance include financial assets measured at amortized cost. Previous accounting guidance required recognition of impairment when it was probable the loss has been incurred. Under the CECL model, lifetime expected credit losses are measured and recognized at each reporting date based on historical experience, current conditions and forecasted information. We adopted this standard as of January 1, 2020. Adoption of this standard required the modified retrospective transition method, which resulted in a cumulative-effect adjustment to retained earnings of $3.1 million. The adoption primarily impacted our trade receivables. Our concentrations of credit risks are limited due to the large number of customers and their dispersion across a number of geographic areas. Substantially all of our trade receivables are concentrated in the public and private hospital and healthcare industry in the U.S. and internationally or with distributors or dealers who operate in international markets. Our historical credit losses have not been significant due to this dispersion and the financial stability of our customers. We consider credit losses immaterial to our business and, therefore, have not provided all the disclosures otherwise required by the standard. We have updated our accounting policy disclosure for accounts receivable as follows: Accounts receivable consists of trade and other miscellaneous receivables. We grant credit to customers in the normal course of business and maintain an allowance for doubtful accounts for expected credit losses. Our concentrations of credit risks are limited due to the large number of customers and their dispersion across a number of geographic areas. We determine the allowance for doubtful accounts by geographic market and take into consideration historical credit experience, creditworthiness of the customer and other pertinent information. We make concerted efforts to collect all accounts receivable, but sometimes we have to write-off the account against the allowance when we determine the account is uncollectible. The allowance for doubtful accounts was $77.3 million and $65.0 million as of June 30, 2020 and December 31, 2019, respectively. In August 2018, the FASB issued ASU 2018-15, Intangibles-Goodwill and Other-Internal-Use Software. ASU 2018-15 aligns the requirements for capitalizing implementation costs incurred in a hosting arrangement that is a service contract with the requirements for capitalizing implementation costs incurred to develop or obtain internal-use software. Our policy for capitalizing implementation costs in a hosting arrangement was already aligned with the new guidance. ASU 2018-15 also provides guidance on how these implementation costs are to be recorded in the statement of earnings, balance sheet and statement of cash flows. We adopted this standard on a prospective basis as of January 1, 2020. The adoption of this standard did not have a material impact on our financial position, results of operations or cash flows. There are no recently issued accounting pronouncements that we have not yet adopted that are expected to have a material effect on our financial position, results of operations or cash flows.
