What 21029 covers

Code 21029 describes surgically reducing and reshaping a benign tumor of a facial bone, typically by burring or similar contouring. An oral and maxillofacial surgeon or craniofacial surgeon may perform the procedure when a bony growth creates a prominence or irregular facial contour. The operative approach and extent depend on the lesion’s location and the correction needed; this is not a code for removing a soft-tissue facial mass.

Report the code when the operative documentation supports a benign facial bone tumor treated by contouring. Record the bone and lesion treated, the technique, and the work performed; distinguish contouring from excision of a defined tumor or removal of an exostosis. Medicare assigns a 90-day global period, including the day-before preoperative visit and 90 days of related postoperative care. When multiple procedures occur in the same session, the highest-valued procedure is paid in full and other procedures are subject to the standard 50% reduction. Assistant-at-surgery payment requires documented medical necessity. Co-surgeons and team surgery are not permitted.

21029 billing questions

How is 21029 different from excision of a facial bone tumor?

Use 21029 when the surgeon treats the benign tumor by contouring the facial bone. A separately excised tumor may point to a different procedure code, depending on the bone and technique.

Can 21029 be used for a mandibular or maxillary exostosis?

Do not select 21029 solely because bone was reshaped. Codes 21031 and 21032 describe removal of exostoses of the mandible and maxilla, respectively; base code selection on the documented diagnosis and procedure.

Is related postoperative care separately reported?

Related postoperative care during the 90-day global period is included, as is the day-before preoperative visit.

How are other procedures in the same session paid?

The highest-valued procedure is paid in full, and other procedures are subject to the standard multiple procedure reduction when performed in the same session.

Can an assistant surgeon or co-surgeon be reported?

Assistant-at-surgery payment requires documentation of medical necessity. Co-surgeons and team surgery are not permitted for this code.

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.
