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

What 28100 covers

This service removes or curettes a bone cyst or benign tumor in the talus or calcaneus. An orthopedic surgeon or podiatric surgeon typically performs it in an operating room, using an approach that exposes the affected bone and allows the lesion to be treated. The operative report should identify the bone and lesion and describe the work performed; the code is for these two bones, not other tarsal bones or toe bones.

Select this code when the lesion is in the talus or calcaneus and the procedure does not use a graft; grafted procedures have separate sibling codes. Document the diagnosis, exact site, and whether grafting was performed. CMS assigns a 90-day global period, including the day-before preoperative visit and 90 days of related postoperative care. In a same-session multiple-procedure claim, the highest-valued procedure is paid in full and other procedures at 50%. Bilateral reporting with modifier 50 is paid at 150%. Assistant-at-surgery payment may be made; co-surgeon payment requires supporting documentation, and team surgery is not permitted.
