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.

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.

11603 billing questions

How is the 2.1–3 cm size determined?

Use the greatest clinical diameter of the lesion plus the narrowest margins needed for excision, measured before removal. Do not select the size from the closure length.

When should a different site code be used?

This code is for the trunk, arms, and legs. Lesions on sites such as the face, ear, eyelid, nose, lip, hand, foot, or genitalia use their own anatomic code group.

Is closure separately reported?

Simple closure is included in the excision. A separately documented intermediate or complex repair may be reported when its requirements are met.

Can modifier 50 be used for lesions on both sides?

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

What postoperative care is included?

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

How are multiple procedures in one session paid?

The highest-valued procedure is paid in full, and other procedures performed in the same session are subject to the standard multiple-procedure reduction.

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.
