What 28120 covers

An orthopedic or foot and ankle surgeon removes a portion of the talus or calcaneus. The work may involve shaping or scooping out bone, removing a sequestrum, or excising a segment. Typical clinical reasons include osteomyelitis or a localized bone lesion. The service is generally performed in an operating room, with the operative report identifying the affected bone and the extent of removal.

Choose this code when the documented procedure is a partial excision of the talus or calcaneus, rather than a biopsy alone or removal of a different foot bone. The operative note should support the bone treated, the indication, and the partial excision performed. 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 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.

28120 billing questions

How does this differ from code 28122?

Code 28120 is for partial excision of the talus or calcaneus. Code 28122 addresses partial excision of other tarsal or metatarsal bones.

When is code 28100 a better fit?

Use 28100 for an excisional bone biopsy in the foot when the service is a biopsy, rather than the partial therapeutic excision reported by 28120.

What documentation supports reporting 28120?

The operative report should identify the talus or calcaneus, describe the portion and type of bone removal, and state the clinical reason, such as diseased bone or a localized lesion.

How is bilateral work reported?

When the procedure is performed on both sides, report modifier 50; CMS pays the bilateral procedure at 150%.

Can an assistant or co-surgeon be reported?

CMS restricts payment for an assistant at surgery for this code. Co-surgeon payment requires supporting documentation, and team surgery is not permitted.

What postoperative care is included?

The 90-day global period includes the day-before preoperative visit and 90 days of related postoperative care.

Where these rates come from

FeeBase calculates base physician payments from CMS work, practice-expense and malpractice RVUs, adjusted by each locality’s geographic indexes and the conversion factor. Services without a published rate are labeled, never given a made-up amount. Amounts are Medicare allowed amounts before claim adjustments: not a patient’s bill or a commercial rate.
