The Totalization provisions of all U.S. agreements apply to U.S. retirement, survivors
            and disability insurance (RSDI) benefits but not to special age-72 payments or transitionally
            insured benefits. Thus, U.S. quarters of coverage (QCs) can be combined with periods
            of foreign coverage to establish fully insured status, disability insured status and
            currently insured status but not the insured status required for special age-72 payments
            or transitionally insured benefits.
         
         The same factors of entitlement that apply to regular (non-Totalization) benefits
            also apply to Totalization benefits.
         
         Neither Medicare nor Supplemental Security Income (SSI) benefits are included in Totalization
            agreements. However, a beneficiary entitled to Totalization benefits may simultaneously
            qualify for Medicare or SSI if the beneficiary meets the requirements independently
            of an agreement.
