What is Medicare Part D?
Medicare Part D is prescription drug coverage. It is offered by private insurance companies approved by Medicare. You can get Part D as a standalone plan (if you have Original Medicare) or as part of a Medicare Advantage plan that includes drug coverage (MAPD plan).
Original Medicare (Part A and Part B) does NOT cover most prescription drugs you take at home. If you want drug coverage with Original Medicare, you need to join a standalone Part D plan.
Do I Need Part D Even If I Take No Medications?
This is one of the most common Medicare questions — and the answer may surprise you.
⚠️ Watch Out: The Part D Penalty Is Permanent
If you skip Part D when first eligible and later decide you want it, you may face a permanent late enrollment penalty for every month you went without creditable drug coverage. The penalty is 1% of the national base beneficiary premium ($38.99/month in 2026) for each uncovered month — and it stays with you for life.
Example: Waiting 2 Years to Join Part D
Uncovered months: 24
Penalty: 24% × $38.99 = $9.36/month added to your Part D premium
This penalty is permanent and adjusts each year as the base premium changes.
Many people choose to join a low-premium Part D plan (sometimes as low as $0-$10/month) just to avoid the penalty — even if they currently take no medications. This is often the most cost-effective approach.
What is Creditable Prescription Drug Coverage?
Creditable prescription drug coverage is coverage that is at least as good as Medicare Part D. If you have creditable drug coverage from another source, you can delay joining Part D without a penalty — as long as you enroll within 63 days of losing that coverage.
✓ Common Examples of Creditable Drug Coverage
- • VA prescription drug coverage
- • TRICARE prescription drug coverage
- • Employer or union drug coverage (if certified as creditable)
- • FEHB (Federal Employees Health Benefits) drug coverage
- • COBRA drug coverage (if the original plan was creditable)
⚠️ The 63-Day Rule
When you lose creditable drug coverage, you have 63 days to enroll in Part D without a penalty. If you wait longer than 63 days, you may face the late enrollment penalty.
Part D Frequently Asked Questions
Can I use VA prescriptions instead of Part D?
Yes — VA prescription drug coverage IS considered creditable coverage for Part D. If you have VA drug benefits, you can delay Part D without a penalty. However, VA coverage only covers medications prescribed by VA providers at VA facilities. If you see non-VA doctors, you may need Part D for those prescriptions.
What if I had employer drug coverage?
Employer drug coverage may be creditable — but not always. Your employer is required to notify you each year whether their drug coverage is creditable. If it is creditable and you lose it, you have 63 days to enroll in Part D without a penalty.
What if I waited too long to join Part D?
If you missed your enrollment window without creditable coverage, you may face a permanent penalty. You can still join Part D during the Annual Enrollment Period (October 15 – December 7), but the penalty will be added to your premium. Talk to Darin about your options.
What is Extra Help for Part D?
Extra Help (also called the Low Income Subsidy or LIS) is a federal program that helps people with limited income and resources pay for Part D costs. If you qualify for Extra Help, you may not owe a late enrollment penalty even if you delayed Part D.
