Medicare program; policy and technical changes to the Medicare prescription drug benefit. Final rule.

This final rule codifies clarifications of existing policies associated with the Medicare Prescription Drug Benefit (also known as Medicare Part D), including the following: guidance that certain supplies associated with the administration of insulin are included in the definition of a Part D drug; guidance regarding the statutory exclusion from the definition of a Part D drug of any drug when used for the treatment of sexual or erectile dysfunction, unless that drug is used for an FDA-approved purpose other than sexual or erectile dysfunction; a recent statutory change that allows for the payment of vaccine administration under Part D for Part D covered vaccines; and guidance on plan-to-plan reconciliation and reconciliation with a payer other than the Part D plan of record. This final rule also codifies clarifications of existing policies associated with the Retiree Drug Subsidy (RDS) program, including guidance on aggregating plan options for purposes of meeting the net test for actuarial equivalence and guidance on applying the Medicare supplemental adjustment when calculating actuarial equivalence. In addition, new clarifications and modifications in this final rule include establishing standards with respect to the timely delivery of infusible drugs covered under Part D and modifications to the retiree drug subsidy regulations. This final rule also codifies certain technical corrections to our regulations and clarifies our intent with respect to certain preamble discussions in a prior final rule implementing the Medicare prescription drug benefit.
