(8) When modifier -57, initial decision to perform surgery, is added to an evaluation
and management procedure code, the modifier -57 must indicate that a consultant has taken over
the case and the consultation code is not part of the global surgical service.
(9) When both surgeons use modifier -62 and the procedure has a maximum allowable
payment, the maximum allowable payment for the procedure must be multiplied by 25%. Each
surgeon is paid 50% of the maximum allowable payment multiplied by 25%, or 62.5% of the
MAP. If the maximum allowable payment for the procedure is BR, the reasonable amount must
be multiplied by 25% and be divided equally between the surgeons.
(10) When modifier code -80 is used with a procedure, the maximum allowable
payment for the procedure must be 20% of the maximum allowable payment listed in these rules,
or the billed charge, whichever is less. If a maximum payment has not been established and the
procedure is BR, payment must be 20% of the reasonable payment amount paid for the primary
procedure.
(11) When modifier code -81 is used with a procedure code that has a maximum
allowable payment, the maximum allowable payment for the procedure must be 13% of the
maximum allowable payment listed in these rules or the billed charge, whichever is less. If
modifier code -81 is used with a BR procedure, the maximum allowable payment for the
procedure must be 13% of the reasonable amount paid for the primary procedure.
(12) When modifier -82 is used and the assistant surgeon is a licensed doctor of
medicine, doctor of osteopathic medicine and surgery, doctor of podiatric medicine, or a doctor
of dental surgery, the maximum level of reimbursement must be the same as modifier -80. If the
assistant surgeon is a physician's assistant, the maximum level of reimbursement must be the
same as modifier -81. If an individual other than a physician or a certified physician's assistant
bills using modifier -82, then the charge and payment for the service is reflected in the facility
fee.
(13) When modifier -GF is billed with evaluation and management or minor surgical
services, the carrier shall reimburse the procedure at 85% of the maximum allowable payment, or
the usual and customary charge, whichever is less.
(14) When modifier -95 is used with procedure code 92507, 92521-92524, 97110,
97112, 97116, 97161-97168, 97530, 97535, or those listed in Appendix P of the CPT codebook,
as adopted by reference in R 418.10107, excluding CPT codes 99241-99245 and 99251-99255,
the telemedicine services must be reimbursed according to all of the following:
(a) The carrier shall reimburse the procedure code at the non-facility maximum allowable
payment, or the billed charge, whichever is less.
(b) Supplies and costs for the telemedicine data collection, storage, or transmission must not
be unbundled and reimbursed separately.
(c) Originating site facility fees must not be separately reimbursed.
(15) Modifier -CO must be appended to a procedure code if the procedure was
furnished entirely by the occupational therapy assistant, or if the occupational therapy assistant
(OTA) has provided a portion of a procedure, separately from the part that is furnished by the
occupational therapist, exceeding 10% of the total time for the procedure code. When modifier -
CO is used, the procedure code must be reimbursed at 85% of the maximum allowable payment,
or the usual and customary charge, whichever is less. Modifier -CO and the corresponding 15%
reduction must not be applicable if the occupational therapist has provided more than half of the
timed procedure code without the minutes provided by the OTA.
