Official Description

Arthrotomy, elbow, including exploration, drainage, or removal of foreign body

© Copyright 2025 American Medical Association. All rights reserved.

Common Language Description

An arthrotomy of the elbow, designated by CPT® Code 24000, involves a surgical procedure that allows for direct access to the elbow joint. This procedure is characterized by the opening of the joint capsule, which can be approached from various angles, including posterior, posterolateral, medial, or anterolateral. The primary objective of this intervention is to explore the internal structures of the elbow joint thoroughly. During the procedure, if there is an accumulation of joint fluid, known as effusion, it is drained to alleviate pressure and discomfort. In cases where an infection is suspected, the surgeon will also drain any infected fluid, blood, or purulent material present within the joint space. To ensure a comprehensive examination, any loculated fluid collections are disrupted through blunt dissection techniques. Following the drainage, the joint is meticulously flushed with sterile saline or an antibiotic solution, often utilizing a method called pulsed lavage, which helps to remove any remaining debris and contaminants. If a foreign body, such as a fragment of bone or other material, is identified within the joint, it is carefully located and extracted. After the completion of these steps, drains may be placed to facilitate ongoing fluid management, and the surgical incision is subsequently closed around these drains to promote healing and minimize the risk of complications.

1. Indications

The procedure of arthrotomy of the elbow is indicated for several specific conditions and symptoms that necessitate direct intervention within the joint. These indications include:

  • Joint Effusion - The presence of excess fluid within the elbow joint, which may cause swelling and discomfort, often requires drainage to relieve pressure.
  • Infection - Signs of infection, such as fever, redness, swelling, and purulent discharge, may necessitate exploration and drainage of infected material from the joint.
  • Foreign Body Presence - The identification of a foreign object within the elbow joint that could cause pain, inflammation, or further complications requires surgical removal.
  • Joint Pathology - Various joint pathologies, including but not limited to, severe arthritis or trauma-related injuries, may warrant exploration to assess the extent of damage and guide further treatment.

2. Procedure

The arthrotomy procedure involves several critical steps to ensure effective exploration and treatment of the elbow joint. These steps include:

  • Approach Selection - The surgeon selects an appropriate surgical approach to access the elbow joint, which may be posterior, posterolateral, medial, or anterolateral, depending on the specific condition being treated.
  • Joint Capsule Opening - Once the approach is determined, the joint capsule is carefully incised to gain access to the internal structures of the elbow joint.
  • Exploration of Joint Structures - The surgeon examines the joint structures thoroughly to assess for any abnormalities, such as tears, lesions, or foreign bodies.
  • Fluid Drainage - If joint effusion is present, the accumulated fluid is drained to relieve pressure. In cases of infection, any infected fluid, blood, or purulent material is also evacuated.
  • Loculation Disruption - Any loculated fluid collections are addressed through blunt dissection to ensure complete drainage and prevent future complications.
  • Joint Flushing - The joint is then flushed with sterile saline or an antibiotic solution using pulsed lavage to clear any remaining debris and contaminants from the joint space.
  • Foreign Body Removal - If a foreign body is identified during the exploration, it is located and carefully removed to prevent further irritation or damage to the joint.
  • Drain Placement - After completing the necessary interventions, drains may be placed within the joint to facilitate ongoing fluid management and prevent accumulation.
  • Incision Closure - Finally, the surgical incision is closed around the drains to promote healing and minimize the risk of infection.

3. Post-Procedure

Post-procedure care following an arthrotomy of the elbow involves monitoring for any signs of complications, such as infection or excessive swelling. Patients may be advised to keep the affected limb elevated to reduce swelling and to follow specific instructions regarding activity restrictions. Pain management is typically addressed with prescribed medications, and the surgical site should be kept clean and dry. Follow-up appointments are essential to assess healing, remove drains if placed, and evaluate the need for further rehabilitation or physical therapy to restore function to the elbow joint.

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).
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.
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.
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.)
80 Assistant surgeon: surgical assistant services may be identified by adding modifier 80 to the usual procedure number(s).
