Receivables [Abstract] |
Accounts receivable | Accounts receivable Accounts receivable are reduced by an allowance for doubtful accounts. In evaluating the ultimate collectability of accounts receivable, the Company analyzes its historical cash collection experience and trends for each of its government payors and commercial payors to estimate the adequacy of the allowance for doubtful accounts and the amount of the provision for uncollectible accounts. Management regularly updates its analysis based upon the most recent information available to determine its current provision for uncollectible accounts and the adequacy of its allowance for doubtful accounts. For receivables associated with dialysis patient services covered by Medicare, the Company receives 80% of the payment directly from Medicare as established under the government’s bundled payment system and determines an appropriate allowance for doubtful accounts and provision for uncollectible accounts on the remaining balance due depending upon the Company’s estimate of the amounts ultimately collectible from other secondary coverage sources or from the patients. For receivables associated with services to patients covered by commercial payors that are either based upon contractual terms or for non-contracted health plan coverage, the Company provides an allowance for doubtful accounts by recording a provision for uncollectible accounts based upon its historical collection experience, potential inefficiencies in its billing processes and for which collectability is determined to be unlikely. For receivables associated with the Company’s capitated health plans, the balances remain on the balance sheet for as long as the respective plan years are open, which varies by health plan but is generally two years in length, with collections occurring on a periodic basis throughout the duration of the corresponding plan year. Approximately 1% of the Company’s net accounts receivable are associated with patient pay. The Company’s policy is to reserve 100% of the outstanding accounts receivable balances for dialysis services when those amounts due have been outstanding for more than three months and to reserve 100% of the outstanding accounts receivable balances for services of DaVita Medical Group (DMG, formerly known as HealthCare Partners or HCP) when those amounts due have been outstanding for more than twelve months and when the amount is not subject to a payment plan. During the six months ended June 30, 2017, the Company’s allowance for doubtful accounts decreased by $11,138. This was primarily due to an increase in write-offs of aged balances and timing of adjustments related to the U.S. dialysis and related lab business. There were no unusual transactions impacting the allowance for doubtful accounts.
