What 11643 covers

This service removes a malignant skin lesion from the face, ear, eyelid, nose, or lip, including the margins needed for excision. Dermatologists, plastic surgeons, and other physicians who perform skin cancer surgery may provide it in an office or facility. A basal cell or squamous cell carcinoma on the nose or ear is a typical clinical context. The code is selected by the greatest diameter of the lesion plus the margins taken, not by the final closure length. Document the site, malignant diagnosis, and measurement supporting the size range; report each separately excised lesion according to its own site and size.

Simple closure is included; a separately performed intermediate or complex repair may be reported when supported. Medicare includes related postoperative visits during the 10-day global period. When multiple procedures are performed in the same session, the highest-valued procedure is paid in full and others at 50%. Modifier 50 is inappropriate. Medicare does not pay an assistant at surgery for this service; 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.

11643 billing questions

How is the 2.1-to-3-cm size determined?

Use the greatest diameter of the lesion plus the margins required for excision. Do not use the length of the resulting wound or closure.

When should 11642 or 11644 be used instead?

Use 11642 for the same anatomic group when the lesion plus margins measures 1.1 to 2 cm. Use 11644 when it measures 3.1 to 4 cm.

Can the repair be billed separately?

Simple closure is included. An intermediate or complex repair may be separately reported when that repair is performed and documented.

Can modifier 50 be used for lesions on both sides?

No. The CMS bilateral adjustment does not apply to this code, and modifier 50 is inappropriate.

Are assistant-at-surgery or co-surgeon claims payable?

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

What postoperative care is included?

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

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.
