Official Description

Arthrotomy, radiocarpal or midcarpal joint, with exploration, drainage, or removal of foreign body

© Copyright 2025 American Medical Association. All rights reserved.

Common Language Description

The procedure described by CPT® Code 25040 refers to an arthrotomy of the radiocarpal or midcarpal joint, which involves surgical intervention to explore, drain, or remove foreign bodies from these specific areas of the wrist. The radiocarpal joint is situated between the radius bone, the triangular fibrocartilage, and the proximal row of carpal bones, while the midcarpal joint is located between the two rows of carpal bones. This surgical procedure is typically indicated when there are concerns such as infection, foreign body presence, or other abnormalities within the joint that require direct visualization and intervention. The approach to the joint is determined by the specific condition being addressed, with incisions made either on the dorsal (back) or ventral (front) aspect of the wrist to provide optimal access. During the procedure, careful dissection of soft tissues is performed to protect surrounding nerves and blood vessels, ensuring that the integrity of the wrist's anatomy is maintained. The joint capsule is then incised to allow for direct inspection, drainage of any infectious material, and removal of foreign bodies if necessary, followed by appropriate closure of the joint and surrounding tissues.

1. Indications

The procedure described by CPT® Code 25040 is indicated for various conditions affecting the radiocarpal or midcarpal joints. These indications may include:

  • Infection - Presence of an infection within the joint that requires drainage to alleviate symptoms and prevent further complications.
  • Foreign Body - The presence of a foreign object within the joint that needs to be surgically removed to restore normal function and alleviate pain.
  • Joint Abnormalities - Any abnormalities observed during imaging studies or physical examination that necessitate direct exploration of the joint for diagnosis or treatment.

2. Procedure

The procedure for CPT® Code 25040 involves several critical steps to ensure effective exploration and treatment of the radiocarpal or midcarpal joint. The steps are as follows:

  • Step 1: Incision - An incision is made over the dorsal or ventral aspect of the wrist, depending on which area provides better visualization for the specific condition being addressed. This initial incision allows access to the underlying joint structures.
  • Step 2: Dissection - Soft tissues surrounding the joint are carefully dissected. During this process, it is crucial to protect nearby nerves and blood vessels to prevent any inadvertent damage that could lead to complications.
  • Step 3: Retraction of Tendons - Tendons may need to be retracted to gain adequate access to the joint capsule. This retraction is performed with care to avoid injury to the tendons themselves.
  • Step 4: Incision of Joint Capsule - The joint capsule is incised to allow for direct inspection of the joint space. This step is essential for identifying any abnormalities or pathological conditions present within the joint.
  • Step 5: Inspection and Drainage - The joint is visually inspected for any signs of infection or other issues. If pockets of pus are identified, they are opened and drained to facilitate healing and reduce the risk of further infection.
  • Step 6: Irrigation - The joint space is irrigated with sterile saline or an antibiotic solution as needed to cleanse the area and promote a sterile environment.
  • Step 7: Drain Placement - If necessary, a temporary drain may be positioned within the joint space to allow for continued drainage of any fluid accumulation post-procedure.
  • Step 8: Removal of Foreign Body - If a foreign body is present, it is located, grasped with forceps, and carefully removed from the joint space.
  • Step 9: Closure - After completing the necessary interventions, the joint capsule is closed, followed by the layered closure of the overlying soft tissue and skin to ensure proper healing.

3. Post-Procedure

Post-procedure care following an arthrotomy of the radiocarpal or midcarpal joint includes monitoring for signs of infection, managing pain, and ensuring proper healing of the surgical site. Patients may be advised to limit movement of the wrist to facilitate recovery and prevent complications. Follow-up appointments are typically scheduled to assess the healing process and to remove any drains if placed during the procedure. Rehabilitation exercises may be recommended to restore function and strength to the wrist as healing progresses.

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).
LT Left side (used to identify procedures performed on the left side of the body)
22 Increased procedural services: when the work required to provide a service is substantially greater than typically required, it may be identified by adding modifier 22 to the usual procedure code. documentation must support the substantial additional work and the reason for the additional work (ie, increased intensity, time, technical difficulty of procedure, severity of patient's condition, physical and mental effort required). note: this modifier should not be appended to an e/m service.
50 Bilateral procedure: unless otherwise identified in the listings, bilateral procedures that are performed at the same session, should be identified by adding modifier 50 to the appropriate 5 digit code. 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.
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.
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.
