I turned 65 in August 2026 and applied for Medicare Part B on October 4. What happens if my application is still pending when I retire on November 30, 2026?

If your Medicare Part B application is still pending when you retire on November 30, 2026, you will experience a temporary gap in active insurance coverage and may need to rely on retroactive processing or temporary documentation.

What Happens to Your Coverage

• Potential Coverage Gap: If Social Security has not finalized your Part B approval by December 1, 2026, you will not have an active Medicare Part B number or card on hand the day your employer health plan ends.

• Retroactive Protection: Once your Part B application is approved, Medicare coverage is generally made retroactive to your requested Special Enrollment Period (SEP) start date (typically December 1, 2026, if you retired on November 30 and requested coverage for the first of the month).

• Out-of-Pocket Billing (Interim Visits): If you visit a doctor or receive outpatient services in December 1926 while your application is pending, the provider may temporarily charge you out-of-pocket or turn you away until the claim can be billed retroactively to Medicare once your approval and Medicare Beneficiary Identifier (MBI) go through

Since you applied on October 4, while still within your Initial Enrollment Period, your Part B coverage would generally begin on November 1, 2026.

I recommend contacting Social Security to confirm your application status and effective date before retiring on November 30. This will help prevent a gap in coverage.

If your Part B application is still pending when you retire November 30, you could have a gap in coverage if your employer insurance ends before Medicare starts. I'd contact Social Security now to check your application status and confirm your Part B effective date so you're not left without coverage.

If there is a temporary gap in your coverage, you could be risking some penalties. Your Part B coverage will start on November 1, 2026. It is recommended that you continuously check your account in the SSA.gov website daily. Usually the online portal will display your Medicare number prior to you receiving your permanent card. Ultimately, you may end up paying out of pocket.
