The changes introduced to social security benefits from time to time are of interest to social security attorneys, the medical review companies assisting them, and the beneficiaries themselves. It is expected that Social Security?s Old Age and Survivors Insurance Trust (OASI) could face depletion by the year 2033.

The social security retirement program is dynamic and is constantly changing in keeping with the U.S. inflation rate, longevity and a number of other factors.
