What 21013 covers

This code describes excision of a soft-tissue tumor beneath the fascia in the face or scalp, including a lesion within muscle, when the tumor is smaller than 2 cm. The surgeon removes the deep mass rather than a superficial skin or subcutaneous lesion. Otolaryngologists, plastic surgeons, and oral and maxillofacial surgeons may perform this procedure in an operating room or an appropriately equipped outpatient setting.

Select the code using the tumor’s depth and size, not the skin incision length: the operative report should identify the facial or scalp site, the tissue plane or muscle involved, and the tumor measurement. This major surgery has a 90-day global period, which includes the day-before preoperative visit and 90 days of related postoperative care. When multiple procedures are performed 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 services may be paid; co-surgeon and team-surgery billing 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.

21013 billing questions

How is this code distinguished from a superficial facial lesion excision?

Use this code for a tumor beneath the fascia, including an intramuscular mass, that is under 2 cm. A lesion limited to the subcutaneous plane belongs to the superficial-lesion code family.

Which size measurement supports code selection?

Document the tumor measurement and its tissue depth in the operative report. The 2 cm threshold concerns the tumor, not the incision.

Does the code include the related postoperative visits?

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

How are other procedures paid when performed in the same session?

The highest-valued procedure is paid in full, and other procedures are subject to the standard multiple-procedure reduction, with payment at 50%.

Can an assistant surgeon or co-surgeon be reported?

Assistant-at-surgery services may be paid. CMS does not permit co-surgeon or team-surgery billing 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.
