Before January 1, 1992, Medicare payments for physicians' services under Part B were limited by the Medicare Economic Index (MEI), which capped prevailing charges. Beginning January 1, 1992, Medicare payments for physicians' services under Part B are made based on a fee schedule. Annual updates to the conversion factor used in establishing the physician fee schedule are based in part on the MEI. This final rule revises the method used to calculate the MEI to more accurately reflect year-to-year price changes affecting the cost of providing physicians' services, thus ensuring appropriate adjustment of Medicare payments.
