Turning 65 is one of the most important Medicare decision points of your life. Your Initial Enrollment Period (IEP) is a 7-month window — 3 months before your birthday month, your birthday month, and 3 months after. Missing it can mean permanent premium penalties and coverage gaps. This checklist covers every step.

1

Social Security & Medicare Timing

  • Confirm whether you are already receiving Social Security benefits (if so, Part A and Part B enrollment may be automatic)
  • If not yet receiving Social Security, contact Social Security to enroll in Medicare Part A and Part B separately
  • Verify your Medicare card arrives and your effective dates are correct
  • Understand that Part A (hospital) is usually premium-free; Part B (outpatient) has a monthly premium
2

Employer Coverage Questions

  • Determine whether you or your spouse still has active employer coverage
  • If you have creditable employer coverage, you may be able to delay Part B without penalty
  • Confirm with your HR department whether your employer plan is 'primary' or 'secondary' to Medicare
  • Understand your Special Enrollment Period (SEP) when employer coverage ends
  • Do NOT assume employer coverage automatically transitions to Medicare — confirm the details
3

HSA Considerations

  • Stop contributing to your Health Savings Account (HSA) at least 6 months before enrolling in Part A
  • Part A enrollment can be backdated up to 6 months — this can create unexpected HSA contribution penalties
  • You can still use existing HSA funds after enrolling in Medicare — you just cannot contribute new funds
4

Medigap Open Enrollment Period

  • Your Medigap Open Enrollment Period (OEP) begins the month you are both 65 and enrolled in Part B
  • During your OEP, you have guaranteed issue rights — carriers cannot deny you or charge more based on health
  • Your OEP lasts 6 months and does NOT repeat — missing it means future Medigap applications may require medical underwriting
  • Compare Plan G and Plan N options during your OEP — this is the best time to lock in coverage
  • Call William to compare Medigap options from the carriers he represents before your OEP closes
5

Part D Drug Coverage

  • List all your current prescription medications (name, dosage, frequency)
  • Compare Part D plans using Medicare's Plan Finder tool at Medicare.gov
  • Enroll in a Part D plan during your IEP to avoid the late enrollment penalty
  • Confirm your preferred pharmacy is in-network for the plan you choose
  • Review your Part D plan annually during Open Enrollment (Oct 15 – Dec 7) — formularies change
6

Doctors & Prescriptions

  • Confirm your primary care physician accepts Medicare
  • Confirm your specialists accept Medicare
  • With a Medigap plan, you can see any Medicare-accepting provider nationwide — no network restrictions
  • With Medicare Advantage, confirm your doctors are in-network before enrolling
7

Retirement Date & Coverage Gap

  • Identify your exact retirement date and when your employer coverage ends
  • Coordinate your Medicare effective date to avoid a gap in coverage
  • If retiring mid-month, confirm whether your employer coverage ends at the end of that month
  • Plan your Medigap application timing to align with your Part B effective date
8

Travel & Lifestyle

  • If you travel frequently, consider a Medigap plan — it covers you at any Medicare-accepting provider nationwide
  • Some Medigap plans (Plan G) include foreign travel emergency coverage
  • Medicare Advantage plans are generally limited to a service area — review coverage before traveling
9

Questions to Ask William

  • Which Medigap plan fits my doctors, prescriptions, and budget?
  • Which carriers do you represent in my area?
  • What is the rate history for the carriers you recommend?
  • Should I choose Plan G or Plan N given my health situation?
  • How does my employer coverage affect my Medicare enrollment timeline?
  • What happens to my coverage if I move after I enroll?
