Official Description

Synovectomy, proximal interphalangeal joint, including extensor reconstruction, each interphalangeal joint

© Copyright 2025 American Medical Association. All rights reserved.

Common Language Description

The CPT® Code 26140 refers to a surgical procedure known as synovectomy of the proximal interphalangeal joint, which includes the reconstruction of the extensor mechanism for each interphalangeal joint involved. The proximal interphalangeal (PIP) joint is one of the key joints in the fingers, located between the first (proximal) and second (distal) phalanges. This procedure is typically indicated when there is inflammation of the synovial tissue, which can occur due to various conditions such as rheumatoid arthritis or other inflammatory joint diseases. The synovium is the lining of the joint that produces synovial fluid, which lubricates the joint and allows for smooth movement. When this tissue becomes inflamed, it can lead to pain, swelling, and decreased range of motion in the affected joint. During the synovectomy, the surgeon makes an incision over the PIP joint to access the joint capsule. The procedure involves careful dissection of the soft tissues while protecting surrounding nerves and blood vessels. Once the joint capsule is exposed, the inflamed synovial tissue is excised to alleviate symptoms and restore function. Additionally, the extensor tendon, which is crucial for finger extension, is reconstructed to ensure that the tendons and ligaments can move freely, allowing for proper finger motion. This procedure is essential for patients experiencing significant joint dysfunction due to synovial inflammation and aims to improve their overall hand function and quality of life.

1. Indications

The procedure described by CPT® Code 26140 is indicated for the following conditions:

  • Inflammatory Joint Disease - Conditions such as rheumatoid arthritis that cause inflammation of the synovial tissue in the proximal interphalangeal joint.
  • Synovitis - Inflammation of the synovial membrane leading to pain and swelling in the joint.
  • Joint Dysfunction - Significant impairment in the range of motion and function of the finger due to synovial inflammation.

2. Procedure

The procedure for CPT® Code 26140 involves several critical steps to ensure effective treatment of the proximal interphalangeal joint.

  • Step 1: Incision - The surgeon begins by making an incision in the skin over the affected proximal interphalangeal joint. This incision allows access to the underlying structures of the joint.
  • Step 2: Dissection - Following the incision, the surgeon carefully dissects the soft tissues surrounding the joint. This step is crucial to protect the nearby nerves and blood vessels while exposing the joint capsule.
  • Step 3: Joint Capsule Exposure - Once the soft tissues are adequately dissected, the joint capsule is exposed and incised. This allows for direct access to the synovial tissue within the joint.
  • Step 4: Synovial Tissue Removal - The inflamed synovial tissue is then excised from the joint. This removal is essential to alleviate the symptoms associated with synovitis and restore joint function.
  • Step 5: Extensor Tendon Reconstruction - After the synovectomy, the extensor tendon is carefully dissected from the surrounding tissue. The reconstruction of the extensor mechanism is performed to ensure that the interconnected tendons and ligaments can move freely, facilitating proper finger extension.

3. Post-Procedure

Post-procedure care following a synovectomy of the proximal interphalangeal joint typically includes monitoring for any signs of infection, managing pain, and ensuring proper healing of the surgical site. Patients may be advised to engage in rehabilitation exercises to restore range of motion and strength in the finger. The recovery period can vary depending on the individual and the extent of the procedure, but it is essential for patients to follow their surgeon's instructions regarding activity restrictions and follow-up appointments to assess healing and function.

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).
52 Reduced services: under certain circumstances a service or procedure is partially reduced or eliminated at the discretion of the physician or other qualified health care professional. under these circumstances the service provided can be identified by its usual procedure number and the 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. note: for hospital outpatient reporting of a previously scheduled procedure/service that is partially reduced or cancelled as a result of extenuating circumstances or those that threaten the well-being of the patient prior to or after administration of anesthesia, see modifiers 73 and 74 (see modifiers approved for asc hospital outpatient use).
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.
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.
74 Discontinued out-patient hospital/ambulatory surgery center (asc) procedure after administration of anesthesia: due to extenuating circumstances or those that threaten the well being of the patient, the physician may terminate a surgical or diagnostic procedure after the administration of anesthesia (local, regional block(s), general) or after the procedure was started (incision made, intubation started, scope inserted, etc). under these circumstances, the procedure started but terminated can be reported by its usual procedure number and the addition of modifier 74. note: the elective cancellation of a service prior to the administration of anesthesia and/or surgical preparation of the patient should not be reported. for physician reporting of a discontinued procedure, see modifier 53.
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.)
80 Assistant surgeon: surgical assistant services may be identified by adding modifier 80 to the usual procedure number(s).
