CPT code 24116: Bone lesion surgery, humerus, allograft reconstruction2026 Medicare rate & RVUs in California

CMS doesn’t publish an office rate for 24116 in California.

Medicare allowed amount for participating (non-QP) physicians, before deductible, coinsurance and claim adjustments. Not a patient’s bill or a hospital charge.

What 24116 covers

An orthopedic surgeon removes or curettes a benign bone cyst or tumor in the humerus and uses donor bone graft to reconstruct the resulting defect. This is generally an operating-room procedure rather than an office service; CMS recorded facility services for this code in 2024 and no office services.

Select this code when the operative report supports a benign lesion in the humerus, its excision or curettage, and use of allograft. The related day-before preoperative visit and 90 days of postoperative care are included in the 90-day global period. For other procedures performed in the same session, CMS pays the highest-valued procedure in full and other procedures at 50%. Bilateral reporting with modifier 50 is paid at 150%. An assistant at surgery may be paid; co-surgeon and team-surgery payment are not permitted for this code.

24126Bone lesion surgeryRadius, with allograft

Both specify allograft reconstruction for a benign bone lesion, but 24126 is for the radius rather than the humerus.
