what is the medicare coordination period
ESRD coordination period calculator. Beneficiaries eligible for Medicare due to ESRD (end-stage renal disease) are subject to a coordination period of 30 months regardless of the type of coverage available to the beneficiary. Once this period has transpired, Medicare becomes the primary payer. During the coordination period, claims are submitted to the beneficiaryâs primary payer for payment and then to Medicare with the explanation of benefits in order to be considered for secondary payment.
