SEC. 4053. APPLICATION OF MAXIMUM ALLOWABLE ACTUAL CHARGE (MAAC). (a) Application on Individual Charge Basis.— Section 1842(j)(1) of the Social Security Act (42 U.S.C. 1395u(j)(1)) is amended— (1) in the first sentence of subparagraph (B)(i), by striking “each such physician’s actual charges” and inserting “the actual charges of each such physician”; (2) in the second sentence of subparagraph (B)(i), by striking “for such a service a physician’s actual charge {as defined in subparagraph (C)(vi)” and inserting “on a repeated basis for such a service an actual charge”; and (3) in subparagraph (C)(vi), by striking “and subparagraph (B)”. (b) Adjustment.— In the case of a physician who did not have actual charges under title XVIII of the Social Security Act for a procedure in the calendar quarter beginning on April 1, 1984, but who establishes to the satisfaction of a carrier that he or she had actual charges (whether under such title or otherwise) for the procedure performed prior to June 30, 1984, the carrier shall compute the maximum allowable actual charge under section 1842(j) of the Social Security Act for such procedure performed by such physician in 1988 based on such physician’s actual charges for the procedure. (c) Effective Date.— The amendment made by subsection (a) shall apply to charges imposed for services furnished on or after April 1, 1988.
