It depends on which program you are enrolled in.

QMB:

    Your Medicare Part B monthly premium will no longer be deducted from your Social Security check. If you have to pay Part A premiums because you do not have 10 years of documented work history in the US, QMB will pay the Part A premium for you.
    AND
    You should not have to pay anything to see a doctor who participates in Medicare or Medicaid or is in your Medicare private health plan’s network. By law, these doctors are not allowed to charge you anything for a service, whether you are in Original Medicare or a Medicare private health plan (Medicare Advantage). If your provider bills you incorrectly, you should call your local State Health Insurance Assistance Program (SHIP).

    SLMB or QI:

      Your Medicare Part B monthly premium will no longer be deducted from your Social Security check.

      If you enroll in a Medicare Savings Program, you will also automatically get Extra Help, the federal program that helps pay most of your Medicare prescription drug costs (Part D).
