Your Medicare Enrollment Timeline
| When | What to Do |
|---|---|
| 12 months before 65 | Start learning about Medicare. Research Original Medicare vs. Medicare Advantage. Review your current medications. |
| 6 months before 65 | Decide if you need to enroll now or can delay (employer coverage). Contact a Medicare agent to review options. |
| 3 months before birthday | Your Initial Enrollment Period (IEP) begins. Enroll in Part A and Part B through Social Security (ssa.gov or 1-800-772-1213). |
| Birthday month | Part A and Part B coverage begins if you enrolled in the first 3 months of your IEP. |
| Within 6 months of Part B start | Medigap Open Enrollment Period—guaranteed-issue rights to buy any Medigap plan. |
| 3 months after birthday | IEP ends. Enroll in Part D or Medicare Advantage by this date to avoid gaps. |
Key Decisions When You Turn 65
1. Do I Need to Enroll Now?
If you have health insurance through your own or your spouse's current employer (with 20+ employees), you may be able to delay Part B enrollment without penalty. If you are retiring or losing employer coverage, enroll during your IEP.
2. Original Medicare or Medicare Advantage?
This is the biggest decision. Compare the two paths and consider your preferred doctors, medications, budget, and travel habits. Compare plans in your NM county.
3. Do I Need Medigap?
If you choose Original Medicare, a Medigap plan helps cover out-of-pocket costs. Your best time to buy is during your 6-month Medigap Open Enrollment Period. Learn about Medigap in NM.
4. Do I Need Part D?
If you are not getting drug coverage through Medicare Advantage or employer coverage, enroll in a standalone Part D plan to avoid late enrollment penalties.
