Understanding Creditable Coverage and Medicare Part D
Creditable Coverage FAQ
-
Creditable coverage means your current prescription drug plan is at least as good as Medicare Part D. If it is creditable, you can delay enrolling in Part D without paying a late enrollment penalty.
-
If you go without creditable drug coverage for 63+ days and later enroll in Medicare Part D, you may face a lifetime late enrollment penalty. Having creditable coverage protects you from this.
-
Examples include:
• VA benefits (Veterans Affairs)
• TriCare for Life (TFL)
• Employer group health plans — if the employer has 20 or more full-time employees
Note: Smaller employers (under 20 employees) may not meet Medicare’s standard, making Medicare the primary payer.
-
Maybe not. Due to federal changes, the out-of-pocket maximum for Medicare Part D will drop to $2,000 in 2025, making it harder for employer plans to remain creditable in 2026 without changes. High Deductible Health Plans (HDHPs) and HSA-compatible plans are especially at risk of losing creditable status.
-
Your employer must send a Creditable Coverage Notice each year, usually in October. If you did not receive one, contact your HR department or benefits administrator and request it.
-
• Confirm your drug plan is creditable every year
• Ask your employer if they plan to maintain creditable status after 2025
• Keep all documentation showing proof of creditable coverage
-
Yes. Keep:
• All Creditable Coverage Notices
• Any HR letters or emails confirming your coverage
• Proof of active group health insurance
CMS may require this if there’s any dispute later. Verbal confirmation is not enough.
