    CPT 29824: Arthroscopic Distal Clavicle Resection (Mumford Procedure)

    Medicare pays $652 and commercial payers pay $2211 on average nationally for this procedure.

    CPT code 29824 describes an arthroscopic distal clavicle resection (Mumford procedure) in which the provider uses an arthroscope and instruments to remove a portion of the clavicle to relieve pain from chronic inflammatory conditions, impingement, or bone spurs; service type: arthroscopic shoulder surgical procedure; typical site of service: hospital outpatient department or ambulatory surgical center.

    National Reimbursement Benchmarks

    Medicare’s national mean rate of $652.20 for CPT 29824 sits well below BUCA’s average commercial mean of $2,210.60, reflecting a substantial gap between federal program reimbursement and aggregated commercial pricing. That difference of $1,558.40 highlights how commercial arrangements — represented by BUCA here — tend to pay multiple times Medicare’s average for this arthroscopic knee procedure, with other major commercial payers’ means (e.g., Blue Cross Blue Shield $3,164.60; UnitedHealth Group $1,202.90; Cigna $1,125.60; Aetna $487.40) distributed around those endpoints.

    Dispersion measured as the interquartile range (P75−P25) is widest for Blue Cross Blue Shield at $2,507.60 and narrowest for Aetna at $606.00, indicating BCBS has the largest middle-50% spread while Aetna’s middle range is relatively tight. UnitedHealth Group ($734.80) and BUCA ($1,731.60) show moderate dispersion, with Cigna’s IQR at $765.20; Medicare’s IQR is small at $59.00 based on available locality percentiles, reflecting relatively low variation across its localities compared with most commercial payers.

    Clinical & Coding Specifications

    Clinical Context

    A 58-year-old patient with a 2-year history of progressive right shoulder pain, worse with overhead activity and nighttime awakening, presents after failing conservative measures including physical therapy, NSAIDs, and corticosteroid injections. Imaging (radiographs and MRI) demonstrates acromioclavicular joint arthritic changes with distal clavicle osteophyte formation and impingement of the rotator cuff interval without a full-thickness reparable cuff tear. The orthopedic surgeon evaluates the patient in clinic, documents persistent pain localized to the acromioclavicular joint and subacromial space, and recommends an arthroscopic distal clavicle excision (arthroscopic Mumford) to remove the symptomatic distal clavicle portion and address impinging spurs.

    In the perioperative workflow the patient completes pre‑op evaluation and informed consent. Intraoperatively the surgeon performs diagnostic shoulder arthroscopy to inspect the glenohumeral joint and subacromial space, then uses arthroscopic instruments to resect the distal clavicle fragment and smooth bone edges. Concomitant procedures (for example, subacromial decompression or biceps tenodesis) may be documented separately if performed. Postoperative documentation includes findings, estimated blood loss, implants (if any), laterality, and specific ICD-10 diagnosis linkage such as M19.011 (right shoulder) or M19.012 (left shoulder). Typical site of service is an ambulatory surgery center or hospital outpatient surgery department for minimally invasive arthroscopic shoulder surgery.
