CPT code 28106: Foot bone lesion, tarsal or metatarsal, autograft2026 Medicare rate & RVUs in California

CMS doesn’t publish an office rate for 28106 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 28106 covers

An orthopedic surgeon or podiatric surgeon uses this code to remove or curette a benign bone cyst or tumor in a tarsal or metatarsal bone and fill the resulting defect with the patient’s own bone graft. The service includes obtaining the autograft. It is generally performed in an operating room or other surgical setting when the lesion requires operative treatment.

Select the code when the operative report supports the tarsal or metatarsal site, removal or curettage of the lesion, and placement of autograft. The 90-day global period includes the day-before preoperative visit and 90 days of related postoperative care. For multiple procedures in the same session, the highest-valued procedure is paid in full and others at 50%. Modifier 50 is inappropriate for this code. Assistant-at-surgery payment may be allowed; co-surgeon payment requires supporting documentation, and team surgery is not permitted.
