How to Apply for Medicare in DC: 2026 Enrollment Guide
Medicare Eligibility in DC
Washington, DC residents are generally eligible to enroll in Medicare at age 65, provided they or their spouse have worked and paid into Medicare through FICA taxes for at least 10 years (a total of 40 quarters of coverage). However, Medicare eligibility in DC also applies to people under 65 who have been receiving Social Security Disability Insurance (SSDI) for 24 months, or those diagnosed with End-Stage Renal Disease (ESRD) or Amyotrophic Lateral Sclerosis (ALS).
- Traditional age-based eligibility: Age 65 or older; U.S. citizen or lawful U.S. resident who has lived in the country for at least five years.
- Under 65 with disabilities: Receiving SSDI for at least 24 months, or diagnosed with ESRD/ALS and meet Social Security criteria.
- Spousal eligibility: Coverage possible through a spouse’s work history if you have not paid enough FICA taxes yourself.
Local data shows that over 12,000 DC residents under 65 have Medicare due to disability-significantly above national averages. Medicare Advantage (Part C) and Part D (prescription drug) plans are available to those who are eligible for Parts A and B and live in the DC plan’s service area.

When to Apply: Key Enrollment Periods
| Period | When | What You Can Do |
|---|---|---|
| Initial Enrollment Period (IEP) | 7 months: 3 before, birth month, 3 after 65th birthday | Sign up for Part A and/or Part B |
| General Enrollment Period (GEP) | Jan 1 – Mar 31 (if you missed IEP) | Enroll in Part A/B; coverage starts July 1 (late penalty applies) |
| Annual Enrollment Period (AEP) | Oct 15 – Dec 7 | Add, drop, or switch Part C and Part D plans |
| Special Enrollment Period (SEP) | Varies (after certain events) | Enroll/change if you lose employer coverage, move, etc. |
Start your application process up to three months before turning 65 for the smoothest transition. If you are receiving Social Security or Railroad Retirement Board benefits at least four months prior to your 65th birthday, you’ll be automatically enrolled in both Part A and Part B and will receive a Medicare card in the mail.
Missing the IEP may mean enrolling during the GEP and potentially facing a lifetime late enrollment penalty for Part B-a 10% increase in your premium for each 12-month period you were eligible but did not enroll. DC-specific deadlines match federal Medicare enrollment periods.

- Proof of U.S. citizenship or legal residency (passport, green card)
