You Get a Medicare Supplement if You Are on Disability — Here's How It Works State by State

Medigap rights for disabled Medicare beneficiaries under 65

After 24 months on SSDI, you're automatically enrolled in Medicare Parts A and B. Part A is usually premium-free. Part B costs $202.90/month in 2026. But Original Medicare still leaves real gaps: the $1,676 Part A deductible, 20% coinsurance on outpatient care, and skilled nursing facility costs up to $209.50/day after day 20.

A Medigap (Medicare Supplement) plan covers those gaps. The catch: the federal 6-month open enrollment guarantee only kicks in at age 65. If you're under 65 on disability, your access to Medigap depends on state law.

Which states guarantee supplement access on disability

Over 30 states require insurers to offer at least some Medigap plans to disabled Medicare beneficiaries under 65. The protections vary widely:

• Some states mandate full guaranteed issue for all standardized plans.
• Others limit access to Plans A and B, or only certain carriers.
• A handful of states have no protections at all for under-65 enrollees.

New Jersey and Pennsylvania rules for disabled enrollees

New Jersey requires Medigap carriers to offer coverage to disabled Medicare beneficiaries under 65 during a guaranteed issue period when they first enroll in Part B. This is a real advantage. Not every state gives you that window.

Pennsylvania also has protections, though the available plan options and pricing differ. In both states, premiums for under-65 enrollees tend to run higher than for 65+ applicants. Comparing carriers matters because the rate spread can be significant.

How to apply for a Medigap plan while on SSDI

Timing is everything. In states with guaranteed issue for disabled enrollees, your window usually opens when your Part B coverage starts. Miss it and you may face medical underwriting or outright denial.

• Know exactly when your Part B effective date is.
• Apply during your state's guaranteed issue window if one exists.
• Compare at least 3-4 carriers. Premiums vary widely for under-65 applicants.
• If your state has no protections, consider a Medicare Advantage plan as an alternative.

Why premiums are higher under 65 and what to expect

Plan G for a 40-year-old on disability can cost $250 to $400/month or more, compared to $100 to $200 for a 65-year-old in the same zip code. Carriers price the risk differently. Some are far more competitive for under-65 enrollees than others.

That $200/month difference between carriers? On a fixed SSDI income, it's groceries. It's a utility bill. This is why working with a broker who knows the under-65 market matters.

Medicare Advantage as an alternative for disabled beneficiaries

If Medigap isn't available or affordable in your state, a Medicare Advantage plan is your other option. Many MA plans charge $0 premiums beyond your Part B cost and include dental, vision, and hearing.

The tradeoff: you'll use a provider network and deal with prior authorizations. For someone seeing multiple specialists, that can be a real consideration. We help you weigh both sides honestly.
