Official Description

Radical resection of capsule, soft tissue, and heterotopic bone, elbow, with contracture release (separate procedure)

© Copyright 2026 American Medical Association. All rights reserved.

Common Language Description

The procedure described by CPT® Code 24149 involves a radical resection of the elbow joint capsule, along with the excision of associated soft tissue and heterotopic bone, specifically aimed at addressing an elbow contracture, commonly known as a stiff elbow. This condition can significantly limit the range of motion in the elbow, leading to functional impairment. The term 'radical resection' indicates a comprehensive surgical approach that not only targets the contracted capsule but also removes any abnormal bone growth that may have developed within the soft tissue, referred to as heterotopic bone. This abnormal bone formation can occur due to various factors, including trauma, neurological injuries, burns, or diseases such as Paget's disease. The surgical technique involves exposing the joint capsule through different approaches—posterior, posterolateral, medial, or anterolateral—depending on the specific characteristics of the contracture. The goal of the procedure is to restore mobility to the elbow joint by meticulously excising the contracted structures and evaluating the range of motion throughout the surgery to ensure optimal outcomes.

1. Indications

The radical resection of the elbow joint capsule, soft tissue, and heterotopic bone is indicated for the treatment of elbow contractures, which may arise from various underlying conditions. The following are specific indications for this procedure:

  • Elbow Contracture A condition characterized by the inability to fully extend or flex the elbow joint, often resulting in functional limitations.
  • Heterotopic Bone Formation The presence of calcified bone within the soft tissue surrounding the elbow, which can develop due to trauma, burns, or other medical conditions.
  • Post-Traumatic Stiffness Stiffness resulting from previous injuries to the elbow that have led to scarring and contracture of the joint capsule.
  • Neurological Conditions Conditions such as head injuries that may contribute to the development of elbow contractures.

2. Procedure

The procedure for radical resection of the elbow joint capsule involves several detailed steps to ensure effective treatment of the contracture. Each step is crucial for achieving the desired outcome of restoring mobility to the elbow joint.

  • Step 1: Approach Selection The surgeon selects an appropriate surgical approach based on the location and type of contracture. Common approaches include posterior, posterolateral, medial, or anterolateral, allowing for optimal access to the joint capsule.
  • Step 2: Incision For a posterolateral approach, a proximal incision is made starting from the lateral supracondylar ridge, extending to the lateral epicondyle, and curving distally to the posterior border of the ulna. This incision provides access to the underlying structures.
  • Step 3: Exposure of the Joint Capsule The anterior musculature is carefully stripped away to expose the anterior capsule. Key muscles such as the extensor carpi radialis longus (ECRL), brachioradialis, and brachialis are elevated off the joint capsule to facilitate access.
  • Step 4: Identification and Protection of Nerves and Ligaments The lateral collateral ligament (LCL) and ulnar nerve are identified and protected during the dissection to prevent injury during the procedure.
  • Step 5: Dissection of the Common Extensor Tendon The common extensor tendon is dissected off the LCL and joint capsule to allow for further access to the contracted structures.
  • Step 6: Excision of Contracted Structures The joint capsule is incised and elevated, allowing for the excision of the contracted portion of the capsule, along with any associated contracted soft tissue and heterotopic bone.
  • Step 7: Evaluation of Range of Motion Throughout the procedure, the surgeon evaluates the range of motion by flexing and extending the joint and assessing the ability to turn the palm up and down. This evaluation helps determine if additional dissection and excision are necessary.
  • Step 8: Wound Repair Once optimal mobility is achieved, the surgical wound is repaired in layers, and appropriate dressings are applied to promote healing.

3. Post-Procedure

After the radical resection procedure, post-operative care is essential for recovery. Patients are typically monitored for any signs of complications, such as infection or excessive swelling. Rehabilitation may be initiated to restore strength and function to the elbow joint, often involving physical therapy to improve range of motion and prevent stiffness. The expected recovery period can vary based on individual circumstances, but patients are generally advised to follow specific guidelines provided by their healthcare team to ensure optimal healing and regain full use of the elbow.

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.
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).
54 Surgical care only: when 1 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 usual procedure number.
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.
62 Two surgeons: when 2 surgeons work together as primary surgeons performing distinct part(s) of a procedure, each surgeon should report his/her 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 co-surgery once using the same procedure code. if additional procedure(s) (including add-on procedure(s) are performed during the same surgical session, separate code(s) may also be reported with modifier 62 added. note: if a co-surgeon acts as an assistant in the performance of additional procedure(s), other than those reported with the modifier 62, during the same surgical session, those services may be reported using separate procedure code(s) with modifier 80 or modifier 82 added, as appropriate.
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).
81 Minimum assistant surgeon: minimum surgical assistant services are identified by adding modifier 81 to the usual procedure number.
82 Assistant surgeon (when qualified resident surgeon not available): the unavailability of a qualified resident surgeon is a prerequisite for use of modifier 82 appended to the usual procedure code number(s).
