Official Description

Synovectomy; metatarsophalangeal joint, each

© Copyright 2025 American Medical Association. All rights reserved.

Common Language Description

The procedure described by CPT® Code 28072 refers to a synovectomy performed specifically on the metatarsophalangeal joint, which is the joint located at the base of the toes where the metatarsal bones meet the proximal phalanges. This surgical intervention is primarily indicated for the treatment of inflammation of the synovial tissue, a condition that can arise from various underlying issues, including rheumatoid arthritis. During the procedure, a surgical incision is made over the affected joint, allowing access to the underlying structures. The soft tissues surrounding the joint are carefully dissected, and the joint capsule is incised to expose the synovial membrane. The inflamed synovial tissue is then meticulously removed, often utilizing a motorized suction shaving device to ensure thorough excision while minimizing damage to surrounding tissues. It is important to note that this code is specifically designated for each metatarsophalangeal joint treated, distinguishing it from similar procedures performed on intertarsal or tarsometatarsal joints, which are coded differently (CPT® Code 28070).

1. Indications

The synovectomy procedure indicated by CPT® Code 28072 is performed for specific conditions that lead to inflammation of the synovial tissue in the metatarsophalangeal joint. The following are the explicitly provided indications for this procedure:

  • Rheumatoid Arthritis - A chronic inflammatory disorder that affects the joints, leading to synovial inflammation and pain.
  • Synovitis - Inflammation of the synovial membrane, which can cause swelling, pain, and reduced joint mobility.
  • Other Inflammatory Joint Conditions - Various other conditions that may result in synovial tissue inflammation and necessitate surgical intervention.

2. Procedure

The synovectomy procedure involves several critical steps to ensure effective removal of the inflamed synovial tissue. The following procedural steps are outlined:

  • Step 1: Incision - The procedure begins with the surgeon making a precise incision over the affected metatarsophalangeal joint. This incision is strategically placed to provide optimal access to the joint while minimizing damage to surrounding tissues.
  • Step 2: Dissection of Soft Tissues - Following the incision, the surgeon carefully dissects the soft tissues surrounding the joint. This step is crucial for exposing the joint capsule without compromising the integrity of adjacent structures.
  • Step 3: Incision of the Joint Capsule - Once the soft tissues are adequately dissected, the joint capsule is incised. This allows direct access to the synovial membrane, which is the target of the procedure.
  • Step 4: Removal of Inflamed Synovial Tissue - The inflamed synovial tissue is then removed using a motorized suction shaving device. This specialized instrument aids in the efficient excision of the tissue while minimizing trauma to the surrounding joint structures.

3. Post-Procedure

After the synovectomy procedure is completed, post-operative care is essential for optimal recovery. Patients are typically monitored for any immediate complications, and pain management strategies are implemented as needed. Rehabilitation may include physical therapy to restore joint function and mobility. The expected recovery time can vary based on individual patient factors and the extent of the procedure, but patients are generally advised to follow specific post-operative instructions provided by their healthcare provider to ensure proper healing and minimize the risk of complications.

59 Distinct procedural service: under certain circumstances, it may be necessary to indicate that a procedure or service was distinct or independent from other non-e/m services performed on the same day. modifier 59 is used to identify procedures/services, other than e/m services, that are not normally reported together, but are appropriate under the circumstances. documentation must support a different session, different procedure or surgery, different site or organ system, separate incision/excision, separate lesion, or separate injury (or area of injury in extensive injuries) not ordinarily encountered or performed on the same day by the same individual. however, when another already established modifier is appropriate it should be used rather than modifier 59. only if no more descriptive modifier is available, and the use of modifier 59 best explains the circumstances, should modifier 59 be used. note: modifier 59 should not be appended to an e/m service. to report a separate and distinct e/m service with a non-e/m service performed on the same date, see modifier 25.

51 Multiple procedures: when multiple procedures, other than e/m services, physical medicine and rehabilitation services or provision of supplies (eg, vaccines), are performed at the same session by the same individual, the primary procedure or service may be reported as listed. the additional procedure(s) or service(s) may be identified by appending modifier 51 to the additional procedure or service code(s). note: this modifier should not be appended to designated "add-on" codes (see appendix d).
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 that the performance of a procedure or service during the postoperative period was: (a) planned or anticipated (staged); (b) more extensive than the 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 (eg, unanticipated clinical condition), see modifier 78.
76 Repeat procedure or service by same physician or other qualified health care professional: it may be necessary to indicate that a procedure or service was repeated by the same physician or other qualified health care professional subsequent to the original procedure or service. this circumstance may be reported by adding modifier 76 to the repeated procedure or service. note: this modifier should not be appended to an e/m service.
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: it may be necessary to indicate that another procedure was performed during the postoperative period of the initial procedure (unplanned procedure following initial procedure). when this procedure is related to the first, and requires the use of an operating/procedure room, it may be reported by adding modifier 78 to the related procedure. (for repeat procedures, see modifier 76.)
79 Unrelated procedure or service by the same physician or other qualified health care professional during the postoperative period: the individual 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. (for repeat procedures on the same day, see modifier 76.)
