Short answer: If your Medicare Advantage plan includes Part D, that drug coverage normally ends with the plan. Returning to Original Medicare does not automatically provide broad outpatient drug coverage, so you may need a stand-alone Part D plan.
Does Original Medicare include prescriptions?
Original Medicare covers certain drugs in limited settings, such as some medications administered by a clinician. It does not cover most prescriptions filled at a retail or mail-order pharmacy. A stand-alone Part D plan is the usual way to add that coverage.
How to avoid a gap
• Confirm the final day of the current drug coverage. • List every medication, dosage, quantity, and pharmacy. • Compare replacement plans using Medicare Plan Compare. • Enroll in time for the new coverage to begin when the old coverage ends. • Save confirmation and verify enrollment with the new plan.
Why creditable coverage matters
If you go without Part D or other creditable prescription coverage for 63 consecutive days or more after an eligible enrollment period, you may owe a Part D late-enrollment penalty if you enroll later. The penalty can continue as long as you have Part D.
Do not add Part D blindly
Most HMO and PPO Medicare Advantage plans include Part D. Joining a separate drug plan while enrolled in one of these plans can disenroll you from Medicare Advantage and return you to Original Medicare. Confirm compatibility before enrolling.
Compare more than the formulary
Check tiers, deductible, copayments or coinsurance, prior authorization, step therapy, quantity limits, preferred pharmacies, specialty-pharmacy rules, and annual estimated costs. Formularies and pharmacy networks vary even among plans from the same insurer.
Frequently asked questions
Will Medicare automatically assign a Part D plan? - Do not assume it will. Certain people with Extra Help may receive a reassignment notice, but most beneficiaries should actively confirm their drug coverage. Does Medigap cover prescriptions? - Modern Medigap policies do not include Part D. Drug coverage is a separate decision. What if my medicine is not covered? - Speak with the prescriber about covered alternatives and ask the plan about exceptions and appeals. Do not stop medication without clinical guidance.
