Oral and maxillofacial surgery

About 21040: Intraoral excision of benign mandibular lesion

Reports intraoral removal of a benign lesion of the mandible when the procedure requires more than routine dental extraction or simple cyst care.

CPT 21040 describes removal of a benign tumor or cyst from the mandible through an intraoral approach. Oral and maxillofacial surgeons and other surgeons with appropriate training may perform it in an office, ambulatory surgery center, or hospital operating room. The operative work may involve incising oral mucosa, exposing the mandibular lesion, removing it, and closing the site. The code is for a benign lesion, not a malignant jaw tumor or an exostosis.

Select the code based on the documented lesion, mandibular site, and intraoral route; distinguish it from procedures that require osteotomy, address a different jaw, or remove bone for another indication. The operative report should describe the lesion and approach, the removal performed, and any relevant pathology. Medicare assigns a 90-day global period, including the day-before preoperative visit and related postoperative care. When multiple procedures occur 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; co-surgeons and team surgery are not permitted.

21040 billing questions

How is 21040 different from 21046?

21040 is for intraoral removal of a benign mandibular lesion without the osteotomy described for 21046. Report 21046 when the documented procedure requires that intraoral osteotomy.

Can 21040 be reported for a malignant mandibular lesion?

No. This code is for a benign lesion; a malignant mandibular tumor requires the code that describes the applicable malignant-tumor procedure.

What documentation supports 21040?

Document the mandibular location, benign lesion or cyst diagnosis, intraoral approach, and the removal performed. Include pathology findings when available.

Should modifier 50 be used for lesions on both sides?

No. The CMS bilateral adjustment is not appropriate for this code, so do not report it with modifier 50.

How does the 90-day global period affect postoperative visits?

The day-before preoperative visit and related postoperative care during the 90-day period are included in the surgical global package.

Can an assistant or co-surgeon be paid for this procedure?

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