Multiple Procedure Reduction
80.2 - Multiple Procedure Reduction
(Rev. 1, 10-01-03)
A/B MACs (B) make no multiple procedure reductions in the S&I or primary non-
radiologic codes in these types of procedures, or in any procedure codes for which the
descriptor and RVUs reflect a multiple service reduction. For additional procedure codes
that do not reflect such a reduction, A/B MACs (B) apply the multiple procedure
reductions.
