What 11423 covers

This service removes a clinically benign skin lesion from the scalp, neck, hand, foot, or genital area, with the surrounding margin included in the excision. Dermatologists, surgeons, and other qualified clinicians commonly perform it in an office or outpatient setting. The code is selected by both the anatomic group and the excised diameter, measured across the lesion and margins; a 2.1-to-3.0 cm measurement falls in this size level.

The operative note should identify the site, lesion, and excised diameter, including margins. A simple closure is included in the excision; a separately reportable more extensive repair may be coded when supported. This is a minor procedure with a 10-day global period, so related postoperative visits during that period are included. When multiple procedures occur in the same session, the highest-valued procedure is paid in full and the others are subject to the standard 50% reduction. Modifier 50 is inappropriate. Medicare does not pay an assistant at surgery for this service, 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.

11423 billing questions

How is the 2.1-to-3.0 cm size determined?

Use the excised diameter, including the lesion and margins, rather than the lesion alone. Document the measurement and the anatomic site.

Which nearby code applies when the lesion is on the trunk or an extremity?

For a benign lesion on the trunk or an extremity, use the corresponding 11400-series code based on excised diameter. Code 11403 covers that anatomic group at the 2.1-to-3.0 cm level.

Can the repair be billed separately?

Simple closure is included. A more extensive repair may be separately reported when its complexity and documentation meet the requirements for a repair code.

Can modifier 50 be used for lesions on both sides?

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

Are postoperative visits included?

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

Can an assistant surgeon or co-surgeon be billed?

Medicare does not pay an assistant at surgery for this service. Co-surgeon and team-surgery billing are not permitted.

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.
