What 11623 covers

This code covers surgical removal of a malignant cutaneous lesion from the scalp, neck, hand, foot, or genital skin when the total excision diameter is 2.1–3 cm. Dermatologists and other clinicians who perform skin surgery commonly report it for an outpatient excision, with the specimen typically submitted for pathologic examination. The measured diameter includes the lesion and the margins taken around it, not only the visible lesion.

Choose the code by the anatomic group and the total diameter planned for excision, and document the site, lesion measurement, margins, and resulting excision size. Simple closure is included; an intermediate or complex repair may be separately reportable when performed and documented. CMS assigns a 10-day global period, so related postoperative visits during those 10 days are included. In a same-session multiple-procedure claim, 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, and co-surgeon and team-surgery billing 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.

11623 billing questions

How is the 2.1–3 cm size determined?

Use the total diameter of the lesion plus the margins required for excision, rather than the visible lesion alone. Document the lesion measurement, planned margins, site, and total excision size.

Is simple closure separately reportable?

No. Simple closure is included in the excision; an intermediate or complex repair may be separately reported when supported by the repair performed and its documentation.

Can modifier 50 be used for lesions on both sides?

No. CMS identifies bilateral adjustment as inappropriate for this code. Report the excisions based on the individual lesions and applicable same-session multiple-procedure rules.

How does the 10-day global period affect follow-up?

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

What happens when another procedure is performed in the same session?

The highest-valued procedure is paid in full, and other procedures 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.
