Does Medigap Cover Prescriptions
No Medigap plan covers outpatient prescriptions — drug coverage lives entirely in the separate Part D program (or in some Medicare Advantage plans). Planning the two together is the standard move.
| Coverage Type | Where It Lives |
|---|---|
| Outpatient drugs | Part D only |
| Drugs during hospital stay | Part A (via Medigap gaps coverage) |
| Chemotherapy/infusion at facility | Part B (Medigap covers the 20%) |
| Part D late penalty | 1%/month — separate from Medigap |
The pairing rule
Buy Medigap for medical cost-sharing and Part D for drugs — the combination recreates comprehensive coverage. Skipping Part D at 65 triggers the 1%-per-month lifetime penalty (context in the Part B penalty file), even if you take no medications.
Legacy exception
Older Medigap plans (H, I, J — pre-2006) contained drug coverage; today’s letters A–N contain none. If an agent implies a current plan “includes drugs,” walk away — verify against the standardized benefits on the plans board.
FAQ
Can I add drug coverage to Medigap later?
Yes via Part D each fall, but the late penalty accrues for every uncovered month after 65.
Does Part D change my Medigap price?
No — the two policies are independent.
