101 CMR 316.05
Maximum Allowable Fees - Surgical Services
(1) Surgical and Obstetrical Services. Except as provided elsewhere in this 101 CMR 316.05(1),
the allowable fees for surgical and obstetrical services are the fees listed in 101 CMR
316.05(4)(b), subject to 101 CMR 316.03 and appropriate modifiers, as applicable. (Anesthesia
procedure codes (00100-01999) and corresponding base anesthesia units for purposes of 101
CMR 316.04 are listed in 101 CMR 316.05(4)(a)). Certain codes in 101 CMR 316.05(4)(b) are
identified with an asterisk (*). The allowable fees for these codes are as set forth in 101 CMR
316.05(4)(b), except when any of those codes are billed as part of a facial feminization surgery to
treat gender dysphoria, in which case the allowable fees are those set forth in 101 CMR
316.05(4)(c).
(2) Unless otherwise specified, guidelines, notes, and definitions provided in the 2023 CPT
Coding Handbook are applicable to the use of the procedure codes and modifiers listed below, as
well as their corresponding descriptions. For code descriptions, see the anesthesia and surgery
service code spreadsheets at www.mass.gov/regulations/101-CMR-31600-surgery-and-
anesthesia-services.
(3) Modifiers.
(a) 26: Professional Component. The component of a service or procedure representing the
physician’s or other qualified health care professional’s work interpreting or performing the
service or procedure. (When the physician or other qualified health care professional
component is reported separately, the addition of modifier 26 to the procedure code will
allow payment of the professional component allowable fee (PC Fee) contained in 101 CMR
316.05(4)(b), adjusted by 101 CMR 316.03 as applicable.)
(b) 50: Bilateral Procedure. Payment for bilateral procedures performed at the same
operative session must be identified by the appropriate service code and modifier 50. Only
one claim line is billed for both procedures. (The addition of modifier 50 to the bilateral code
will allow payment of 150% of the allowable fee contained in 101 CMR 316.05(4)(b),
adjusted by 101 CMR 316.03 as applicable, to the eligible provider for performance of both
bilateral procedures.)
(c) 51: Multiple Procedures. This modifier must be used to report multiple procedures
performed at the same session. The service code for the major procedure or service must be
reported without a modifier. The secondary, additional, or lesser procedure(s) must be
identified by adding modifier 51 to the end of the service code for the secondary
procedure(s). (The addition of modifier 51 to the second and subsequent procedure codes
allows payment of 50% of the allowable fee contained in 101 CMR 316.05(4)(b), adjusted by
101 CMR 316.03 as applicable, to the eligible provider. Note: This modifier should not be
used with designated “add-on” codes or with codes in which the narrative begins with “each
additional.”)
(d) 52: Reduced Services. Under certain circumstances, a service or procedure is partially
reduced or eliminated at the physician's or other qualified health care professional’s election.
Under these circumstances, the service provided can be identified by its usual procedure
number and addition of modifier 52, signifying that the service is reduced. This provides a
means of reporting reduced services without disturbing the identification of the basic service.
(e) 54: Surgical Care Only. When one eligible physician or other qualified health care
professional performs a surgical procedure and another provides preoperative and/or
postoperative management, surgical services may be identified by adding modifier 54 to the
appropriate procedure code. (This allows payment of 85% of the allowable fee contained in
101 CMR 316.05(4)(b), adjusted by 101 CMR 316.03 as applicable, to the physician or other
qualified health care professional performing the surgery.)
(f) 55: Postoperative Management Only. When one eligible physician or other qualified
health care professional performs the postoperative management and another performed the
surgical procedure, the postoperative component may be identified by adding modifier 55 to
the appropriate procedure code. (This allows payment of 15% of the allowable fee contained
in 101 CMR 316.05(4)(b), adjusted by 101 CMR 316.03 as applicable, to the physician or
other qualified health care professional.)
(g) 58: Staged or Related Procedure or Service by the Same Physician or Other Qualified
Health Care Professional During the Postoperative Period. It may be necessary to indicate
the performance of a procedure or service during the postoperative period was (a) planned or
anticipated (staged); (b) more extensive than original procedure; or (c) for therapy following
a surgical procedure. This circumstance may be reported by adding modifier 58 to the staged
or related procedure. Note: for treatment of a problem that requires a return to the
operating/procedure room (e.g., unanticipated clinical condition), see modifier 78.
(h) 59: Distinct Procedural Service. To identify a procedure distinct or independent from
other services performed on the same day, add modifier 59 to the end of the appropriate
service code. Modifier 59 is used to identify services/procedures that are not normally
reported together, but are appropriate under certain circumstances; for example, different site
or organ system. However, when another already established modifier is appropriate, it
should be used rather than modifier 59.
(i) 62: Two Surgeons. When two eligible surgeons work together as primary surgeons
performing distinct part(s) of a procedure, each surgeon should report their distinct operative
work by adding modifier 62 to the procedure code and any associated add-on code(s) for that
procedure as long as both surgeons continue to work together as primary surgeons. Each
surgeon should report the procedure once using the same procedure code. If additional
procedure(s) (including add-on procedure(s) are performed during the same surgical session,
separate codes(s) may also be reported with modifier 62 added.) (The addition of modifier 62
to the procedure code allows payment of 57.5% of the allowable fee contained in 101 CMR
316.05(4)(b), adjusted by 101 CMR 316.03 as applicable, to each surgeon. No separate
payment will be made for assisting surgical services in these cases; it is included in the total
surgical fee listed.)
(j) 66: Surgical Team. This modifier must be used to identify highly complex procedures
(requiring the concomitant services of several eligible physicians, often of different
specialties, plus other highly skilled, specially trained personnel, and various types of
complex equipment) carried out under the “surgical team” concept. The unit fee is payable to
the director of the surgical team and includes all assistant surgeon fees; there are no separate
payments for assisting surgical services. The director of the surgical team is expected to
distribute the unit fee to the eligible members of the surgical team.
(k) 76: Repeat Procedure by Same Physician or Other Qualified Health Care Professional.
The physician or other qualified health care professional may need to indicate that a
procedure or service was repeated subsequent to the original procedure or service. This
circumstance may be reported by adding modifier 76 to the repeated procedure/service or the
separate five-digit modifier code 09976 may be used.
(l) 77: Repeat Procedure by Another Physician or Other Qualified Health Care Professional.
The physician or other qualified health care professional may need to indicate that a basic
procedure or service performed by another physician or other qualified health care
professional had to be repeated. This situation may be reported by adding modifier 77 to the
repeated procedure/service or the separate five-digit modifier code 09977 may be used.
(m) 78: Unplanned Return to the Operating/Procedure Room by the Same Physician or Other
Qualified Health Care Professional Following Initial Procedure for a Related Procedure
During the Postoperative Period. The physician or other qualified health care professional
may need to indicate that another procedure was performed during that postoperative period
of the initial procedure. When this subsequent procedure is related to the first, and requires
the use of the operating room, it may be reported by adding modifier 78 to the related
procedure, or by using the separate five-digit modifier 09978. (For repeat procedures on the
same day, see modifier 76.)
(n) 79: Unrelated Procedure or Service by the Same Physician or Other Qualified Health
Care Professional During the Postoperative Period. The physician or other qualified health
care professional may need to indicate that the performance of a procedure or service during
the postoperative period was unrelated to the original procedure. This circumstance may be
reported by using modifier 79 or by using the separate five-digit modifier 09979. (For repeat
procedures on the same day, see modifier 76.)
(o) 80: Assistant Surgeon. Surgical assistant services may be identified by adding modifier
80 to the usual procedure code. (This allows payment of 15% of the allowable fee contained
in 101 CMR 316.05(4)(b), adjusted by 101 CMR 316.03 as applicable, to the eligible
assistant surgeon.)
(p) 82: Assistant Surgeon (when qualified resident surgeon not available). Surgical assistant
services may be identified by adding modifier 82 to the usual procedure code when a
qualified resident surgeon is not available. (This allows payment of 15% of the allowable fee
contained in 101 CMR 316.05(4)(b), adjusted by 101 CMR 316.03 as applicable, to the
eligible assistant surgeon.)
(q) AA: Anesthesia Services Performed Personally by an Anesthesiologist. This allows
