Medicare allowed amount for participating (non-QP) physicians, before deductible, coinsurance and claim adjustments. Not a patient’s bill or a hospital charge.

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.
