Medicare and Disability: When Coverage Starts and What to Expect

After 24 months of receiving SSDI benefits, you become eligible for Medicare regardless of age. If you have employer coverage, the employer size threshold is 100 employees (not 20). At 65, your Medicare transitions seamlessly from disability-based to age-based.

When This Applies

  • You are receiving SSDI disability benefits
  • You have been on SSDI for nearly 24 months
  • You have employer coverage and disability Medicare
  • You are approaching 65 with disability Medicare
