SSDI and Medicare: When Coverage Starts and What's Included
TL;DR: Medicare starts 24 months after your SSDI entitlement date (which is the first month of the 5-month waiting period). That means 29 months after your onset date. Part A (hospital) is premium-free. Part B (outpatient) costs about $185/month (2026). Part D covers prescriptions. You can also get a Medigap supplement. During the 24-month wait, options include concurrent SSI/Medicaid, ACA marketplace plans, COBRA, or state Medicaid expansion.
The 24-month Medicare waiting period is one of the most criticized aspects of SSDI. You're disabled, you need medical care, and you have to wait two years for government health insurance. Here's how to navigate it.
Medicare Timeline
| Month | What Happens |
|---|---|
| Month 1 | SSDI entitlement begins (first month of waiting period) |
| Months 1-5 | 5-month SSDI waiting period (no cash benefits) |
| Month 6 | First SSDI payment |
| Month 25 | Medicare Part A and B begin |
Exception: ALS
If you have ALS (amyotrophic lateral sclerosis), there is no 24-month waiting period. Medicare begins the first month of SSDI entitlement.
