What is Mumford Procedure?

The Mumford procedure, also known as distal clavicle excision or distal clavicle resection, is an orthopedic surgery performed to relieve pain originating from the acromioclavicular (AC) joint. During the operation, the surgeon removes a small portion of the end of the clavicle (collarbone), creating a gap between the clavicle and the acromion. This prevents the arthritic bone surfaces from rubbing against each other, significantly reducing pain while preserving shoulder function. The procedure can be performed through an open incision or, more commonly today, using arthroscopic (minimally invasive) techniques. Arthroscopic surgery generally results in smaller incisions, less soft tissue damage, and faster recovery compared with traditional open surgery.

The Mumford procedure is usually recommended after conservative treatments such as rest, activity modification, physical therapy, anti-inflammatory medications, and corticosteroid injections have failed to relieve symptoms. It is commonly performed for patients with AC joint arthritis, distal clavicle osteolysis (weightlifter's shoulder), chronic AC joint pain, and painful bone spurs. Many patients undergo the Mumford procedure together with other shoulder operations, including rotator cuff repair, subacromial decompression, or labral surgery. Because only a small amount of bone is removed while preserving surrounding ligaments and muscles, most patients regain excellent shoulder mobility and experience significant pain relief after rehabilitation.

Mumford Procedure Shoulder

The shoulder contains several joints, including the glenohumeral joint and the acromioclavicular (AC) joint. The Mumford procedure specifically targets disorders affecting the AC joint, which connects the collarbone to the acromion of the scapula. Degenerative arthritis, repetitive overhead activity, sports injuries, trauma, and heavy weightlifting can gradually damage this joint, causing pain during lifting, pushing, sleeping on the affected side, or reaching across the body. Imaging studies such as X-rays, MRI, or ultrasound often demonstrate joint narrowing, bone spurs, inflammation, or degeneration before surgery is considered.

The procedure is designed to eliminate painful bone-to-bone contact while maintaining shoulder stability. Surgeons generally remove approximately 5–10 mm of the distal clavicle, leaving the surrounding ligaments intact whenever possible. Following surgery, scar tissue naturally fills the gap, preventing painful friction while allowing normal shoulder movement. Most patients report improved daily activities, easier overhead motion, and reduced discomfort once rehabilitation is completed. Long-term outcomes are generally excellent when the diagnosis is appropriate and postoperative physical therapy is followed consistently.

Mumford Procedure Protocol

The rehabilitation protocol following a Mumford procedure is divided into several phases. During the first one to two weeks, patients typically wear a sling primarily for comfort while beginning gentle pendulum exercises and passive range-of-motion activities. Ice therapy, pain control, and swelling reduction are emphasized during this early phase. If additional procedures such as rotator cuff repair are performed simultaneously, rehabilitation may progress more slowly according to the surgeon's recommendations.

Between weeks two and six, patients gradually begin active-assisted and active shoulder motion while avoiding heavy lifting and repetitive overhead activities. Strengthening exercises for the rotator cuff, deltoid, and scapular stabilizers are usually introduced after adequate healing has occurred. Most rehabilitation programs advance to resistance exercises between six and twelve weeks. Return to sports, manual labor, and heavy weightlifting is generally allowed only after shoulder strength, flexibility, and function have been fully restored under medical supervision.

Mumford Procedure Recovery

Recovery following a Mumford procedure varies depending on patient age, general health, occupation, and whether additional shoulder procedures were performed. Many patients experience gradual improvement within the first few weeks, although complete recovery usually requires several months. Mild swelling, soreness, stiffness, and temporary weakness are common during the early healing period. Pain generally improves steadily as inflammation decreases and physical therapy progresses.

Many patients return to desk work within one to two weeks, while individuals performing physically demanding jobs may require two to four months before unrestricted activity. Athletic participation often resumes after three to four months once strength and range of motion have returned. Adhering to physical therapy significantly improves outcomes and helps prevent postoperative stiffness. Most studies report high patient satisfaction and substantial long-term pain relief after distal clavicle excision when performed for appropriate indications. Community experiences shared by patients also commonly describe meaningful pain reduction within approximately 6–8 weeks, although recovery speed varies between individuals. 

Mumford Procedure Cost

The cost of a Mumford procedure depends on factors such as geographic location, hospital or ambulatory surgery center fees, surgeon experience, anesthesia charges, imaging studies, postoperative rehabilitation, and insurance coverage. In the United States, the total cost may range from approximately $5,000 to more than $20,000 for uninsured patients. Arthroscopic procedures performed in outpatient surgery centers are often less expensive than procedures requiring hospital admission.

Patients with private insurance, Medicare, or other health plans often pay substantially less because insurance typically covers medically necessary surgery after conservative treatment has failed. However, deductibles, copayments, coinsurance, physical therapy, and follow-up visits may still result in out-of-pocket expenses. Patients should request an itemized estimate from both the surgeon and the surgical facility before scheduling the operation to better understand the expected financial responsibility.

Mumford Procedure CPT Code

The CPT code used depends on the surgical technique performed. For an open Mumford procedure (partial claviculectomy), the commonly reported CPT code is 23120. For an arthroscopic distal clavicle excision (Mumford procedure), the commonly reported CPT code is 29824. These codes describe removal of the distal clavicle to treat painful AC joint disorders. 

The final code submitted for billing may differ if additional shoulder procedures are performed during the same operation, such as rotator cuff repair, subacromial decompression, labral repair, or biceps tenodesis. Medical coders must also apply appropriate modifiers and follow payer-specific billing guidelines. Because coding rules can vary according to documentation and insurance requirements, providers should verify the correct CPT code before claim submission.
