What 11404 covers

This service involves removing a benign skin lesion from the trunk or an extremity, such as a benign-appearing nevus or epidermal cyst. Dermatologists, primary care clinicians, and surgeons commonly perform it in an office or outpatient procedure setting. The code selection is based on the lesion’s greatest diameter plus the narrowest margins needed for removal, measured before excision—not the length of the resulting wound.

Document the lesion’s site and dimensions, the margins included in the excision, and the procedure performed. Routine simple closure is included; a separately reportable intermediate or complex repair may be coded when performed and documented. Related postoperative visits are included in 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, and 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.

11404 billing questions

How do I distinguish 11404 from 11403 or 11406?

Measure the lesion together with the margins required for excision. Use 11404 when that measurement is 3.1–4 cm; 11403 is for the smaller adjacent size range, and 11406 is for a measurement greater than 4 cm.

Can I report 11404 for a lesion on the hand or face?

No. This code is for the trunk and extremities other than the anatomic areas assigned to separate code series. Hand, foot, neck, and genital sites use the 11420–11426 series; facial sites use the 11440–11446 series.

Is wound closure included?

Simple closure is included in the excision. A separately reportable intermediate or complex repair may be coded when that repair is actually performed and documented.

Does the 10-day global period include postoperative visits?

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

Can modifier 50 be used for lesions removed on both sides?

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

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.
