How does Medicare work with Social Security Disability?

Health coverage follows the program a person is approved for.

SSDI and Medicare. Medicare coverage begins after 24 months of SSDI entitlement. The 24 months count from the first month of benefits, not from the date of the disability. Because benefits start after a five-month waiting period, Medicare typically starts about 29 months after the disability began. A successful claim can also include past-due benefits, and months of past-due entitlement can count toward the 24.

Exceptions. Medicare begins without the 24-month wait for people with end-stage renal disease or ALS.

At 65. Anyone with enough work credits becomes eligible for Medicare at 65, whether or not disabled. SSDI recipients already covered keep Medicare when SSDI converts to retirement at full retirement age. See SSDI at full retirement age.

SSI and Medicaid. SSI is needs-based and generally brings Medicaid, not Medicare. A person approved for both SSDI and SSI can have both. See SSI vs. SSDI.

Before approval. Health coverage during the wait is a real problem for many claimants. Continuing medical treatment also matters for the claim itself, because treatment records are the evidence. See what conditions qualify.
