What 11640 covers

This code covers removal of a malignant skin lesion from the face, ear, eyelid, nose, or lip, with the margins needed for excision. Dermatologists, plastic surgeons, and other qualified physicians commonly perform the procedure in an office or outpatient surgical setting. The size category is based on the excised diameter, including the lesion and margins—not the lesion alone. The code includes simple closure; a separately performed intermediate or complex repair may be reported when supported by the service and documentation.

Choose this code when the anatomic site is one of the specified facial sites and the excised diameter is 0.5 cm or less. Document the lesion’s location and size, the margins taken, and the resulting excised diameter; retain pathology findings supporting the malignant diagnosis. CMS assigns a 10-day global period, so related postoperative visits during that period are included. For multiple procedures 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 is statutorily restricted, and 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.

11640 billing questions

How is the size category determined?

Use the excised diameter, including the lesion and the margins taken, rather than the lesion’s diameter alone. This code is for an excised diameter of 0.5 cm or less.

Which sites qualify for this code?

The site must be the face, ear, eyelid, nose, or lip. For the same size category on a different anatomic group, use the code assigned to that group.

Is simple closure separately reported?

Simple closure is included in the excision service. A separately performed intermediate or complex repair may be reported when its documentation supports that repair.

Are related postoperative visits separately payable during the global period?

Related postoperative visits during the 10-day global period are included in the procedure.

What happens when multiple procedures are performed in the same session?

CMS pays the highest-valued procedure in full and applies the standard multiple procedure reduction to the other procedures.

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.
