Medicare Part D

メディケアパートD(処方薬保険) (medikea pāto D (shohōyaku hoken))

Medicare Part D provides prescription drug coverage available as a standalone plan to complement Original Medicare or included in Medicare Advantage plans. Part D plans have their own monthly premiums, deductibles, and formularies. Coverage tiers affect cost: generic drugs in lower tiers are cheapest, while specialty drugs in higher tiers carry higher cost-sharing. A late enrollment penalty applies for those who delay Part D enrollment without other creditable drug coverage.

Part D beneficiaries should review their plan's formulary annually as drug lists and cost-sharing structures change each year.
