Medicare Advantage and Part D changes
A qualifying event may permit specific plan actions for a limited timefor example moving outside a plans service area losing eligible coverage a plan ending or certain changes involving Medicaid or Extra Help

Situations That May Create a Medicare SEP
| Situation | Coverage question | Best next guide |
|---|---|---|
| Leaving a job or losing employer group coverage after 65 | Do you need Part B and how will employer coverage end dates coordinate with it | Retiring after 65 and CMS 40BCMS L564 forms |
| Moving to a new address | Will you leave a Medicare Advantage or Part D service area or gain new plan choices | Moving with Medicare in Missouri or Illinois |
| A Medicare Advantage or drug plan ends reduces its service area or ends its Medicare contract | What replacement coverage and election rights are available | What happens when a Medicare Advantage plan is ending |
| Gaining losing or changing Medicaid or Extra Help eligibility | Do eligibility changes permit a plan change or affect D SNP enrollment | D SNP enrollment periods and what happens when Medicaid or D SNP eligibility ends |
| Other exceptional conditions | Does a current Medicare rule create a specific election opportunity | Use Medicares official SEP list and confirm the permitted action and deadline before changing coverage |
A Life Change Does Not Permit Every Possible Change
Each SEP is tied to a defined event It may allow only certain elections and the window may begin before or after the event Do not assume that one SEP lets you change every kind of Medicare coverage
Likewise returning to Original Medicare after an eligible Medicare Advantage election does not itself guarantee acceptance into a Medicare Supplement Confirm Medigap underwriting and any guaranteed issue protection before ending existing coverage
Part B SEP After Working Past 65
The working aged Part B SEP generally applies when you delayed Part B while covered by a group health plan based on your or your spouses current employment The enrollment period generally continues while that qualifying coverage is active and for eight months after the employment or coverage ends whichever occurs first
- COBRA does not extend the eight month Part B clock Use the COBRA and Medicare guide
- Retiree coverage is not current employment coverage Coordinate dates before the active employer plan ends
- Employer size can affect payer order Review the Medicare 20 employee rule
- HSA contributions require separate planning See the Medicare and HSA timeline
