If you receive Social Security Disability benefits, you are eligible for Medicare coverage after 24 months of payment. The 24 month period begins from the date you first became entitled to Social Security Disability. If you are unsure of your entitlement date, it is found on the first award letter you received from Social Security. You can also call Social Security’s toll-free number and a representative can give you the date you became entitled and your Medicare effective dates.
When you become entitled to Medicare Social Security will start deducting premiums for your Medicare Parts B and D. In 2006 the premium amount for Medicare Part B is $88.50. Medicare Part D premiums vary by the plan you choose for prescription drug coverage.
If you receive Social Security Disability and SSI, or the amount you receive from Disability is low, your State may pay the Part B premiums for you. The State run program that does this is called “Qualified Medicare Beneficiary,” or QMB. To find out if you qualify for QMB, call Medicare at 1-800-633-4227.
If you receive SSI benefits only, you will not be eligible for Medicare A and B. People who receive SSI benefits are covered by their State’s Medicaid program. In some States you will have Medicare Part D for your prescriptions along with your Medicaid coverage. There are a number of States that are continuing to cover prescriptions through their Medicaid programs; if your state is one of these you will not be enrolled in Medicare Part D.
