Applying Criteria for Reasonable Charge Determinations
80.8 - Applying Criteria for Reasonable Charge Determinations
(Rev. 1, 10-01-03)
B3-5030, B3-5030.2
The reasonable charge determination for a covered service should be based on the actual
charge for the service when that charge is no higher than the applicable customary and
prevailing charges. The A/B MAC (B) should exercise judgment so that its reasonable
charge determinations are realistic and equitable. A/B MACs (B) should take into account
special factors in individual cases that might affect the reasonableness of charges. The
special factors could involve travel, medical complications, or other unusual circumstances
such as prolonged time and attention required by a patient’s condition.
Different services and supplies for which charges are made under Part B, may not be
grouped together for the purpose of making one overall reasonable charge determination.
Thus, in processing a claim for payment a separate reasonable charge determination must
be made with respect to each item for which a charge is made.
