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

What 11641 covers

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

Document the malignant lesion, exact site, and excised diameter including margins. The procedure has a 10-day global period, so related postoperative visits during that period are included. 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. Modifier 50 is inappropriate for this code. Medicare does not pay an assistant at surgery for this service, and co-surgeon and team-surgery billing are not permitted.
