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

What 11603 covers

This service removes a malignant skin lesion from the trunk, an arm, or a leg, including the surrounding margins taken for complete excision. Dermatologists, surgeons, and other qualified practitioners commonly perform it in an office procedure room or an outpatient facility. The removed tissue is typically submitted for pathology. The code applies to an excised diameter of 2.1–3 cm; face, ear, eyelid, nose, lip, hand, foot, and genital sites belong to different anatomic code groups.

Select the size level using the lesion’s greatest clinical diameter plus the narrowest margins needed for excision, measured before removal. Document the site, lesion and margin measurements, malignant diagnosis or clinical basis for excision, and procedure performed. Simple closure is included; a separately documented intermediate or complex repair may be reportable. The 10-day global period includes related postoperative visits during that period. When multiple procedures occur in the same session, the highest-valued procedure is paid in full and others are subject to the standard multiple-procedure reduction. Modifier 50 is inappropriate. Medicare does not pay an assistant at surgery for this service; co-surgeons and team surgery are not permitted.
