CPT code 24147: Olecranon excision, partial bone removal2026 Medicare rate & RVUs in California

CMS doesn’t publish an office rate for 24147 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 24147 covers

The surgeon removes a limited amount of bone from the olecranon, the bony tip of the ulna at the elbow. This may address a painful prominence or osteophyte that causes symptoms or interferes with elbow motion. Orthopedic surgeons most often perform the operation in a hospital or ambulatory surgery setting, sometimes alongside other elbow work when each procedure is separately indicated.

Report the code when the operative record supports partial removal of olecranon bone, rather than treatment of the overlying bursa alone or removal of a bone sequestrum. Document the treated site, the bone removed, and the clinical reason for excision. Medicare assigns a 90-day global period, including the day-before preoperative visit and 90 days of related postoperative care. For multiple procedures in one session, the highest-valued procedure is paid in full and the others at 50%. Bilateral reporting with modifier 50 is paid at 150%. Assistant-at-surgery payment is restricted; co-surgeon payment requires supporting documentation, and team surgery is not permitted.
