What 21026 covers

CPT 21026 describes surgical removal of facial bone, involving one or more bones of the face. An oral and maxillofacial surgeon, plastic surgeon, or otolaryngologist may perform the procedure in an operating room when the treatment plan calls for excision of facial bone. The operative report should identify the bone or bones treated and describe the extent of removal.

Select this code for facial bone excision, distinguishing it from lower-jaw bone excision and from codes describing contouring or a specified tumor operation. Documentation should support the anatomic site and the work 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 other procedures are subject to the standard 50% reduction. Modifier 50 is inappropriate. Medicare does not pay an assistant at surgery for this code; co-surgeons and team surgery are not permitted.

This summary was written with AI assistance from CMS physician fee schedule data and checked against the CMS billing rules shown here. Rates on this page come directly from CMS files.

21026 billing questions

How does 21026 differ from 21025?

21026 describes facial bone excision; 21025 is the jaw-specific code for excision of lower-jaw bone. Choose based on the bone and procedure documented.

When would 21029 be a better fit?

21029 describes contouring facial bone, such as reshaping a bony prominence or lesion. Use 21026 when the documented work is excision rather than contouring.

Should modifier 50 be reported for both sides?

No. CMS identifies bilateral adjustment as inappropriate for 21026, so modifier 50 should not be used.

What postoperative care is included?

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

Can an assistant surgeon or co-surgeon be paid?

Medicare does not pay an assistant at surgery for 21026. Co-surgeons and team surgery are not permitted.

How does the multiple-procedure reduction work?

When multiple procedures are performed in the same session, the highest-valued procedure is paid in full and the other procedures are paid at 50%.

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.
