What 11400 covers
A clinician excises a benign skin lesion from the trunk, an arm, or a leg, removing the lesion with the margin needed for complete removal. A small benign nevus is a typical example. Dermatologists, primary care clinicians, and surgeons commonly perform this procedure in an office or outpatient setting. The code is limited to these anatomic areas; lesions on the face, neck, hands, feet, or genitalia follow different site-specific code families.
Choose the code using the excised diameter, including the planned margins, rather than the visible lesion alone. Document the lesion’s site, its size, the margins removed, and the benign clinical indication. Simple closure is included; a separately documented intermediate or complex repair may be reported when supported. The 10-day global period includes related postoperative visits during that period. When multiple procedures are performed in one session, the highest-valued procedure is paid in full and other procedures are subject to a 50% reduction. Modifier 50 is inappropriate. Medicare does not pay for an assistant at surgery, and co-surgeon or team-surgery reporting is not permitted.

11400 billing questions
How is the size selected?
Use the diameter of the lesion plus the margins removed, measured before excision. This code is for an excised diameter of 0.5 cm or less.
Can this code be used for a lesion on the face or neck?
No. This code is for the trunk, arms, and legs. The 11420 family covers scalp, neck, hands, feet, and genitalia; the 11440 family covers the face.
Is simple closure separately billable?
Simple closure is included in the excision. A separately documented intermediate or complex repair may be reportable when the repair service meets the applicable coding requirements.
What documentation supports reporting this code?
Document the lesion’s benign clinical indication and anatomic site, its size, the margins removed, and the resulting excised diameter. The measurement must support the 0.5 cm-or-less size level.
How are other procedures in the same session paid?
CMS pays the highest-valued procedure in full and applies a 50% reduction to the other procedures in the session. Modifier 50 is inappropriate for this code.
Are assistant or co-surgeon services payable?
Medicare does not pay an assistant-at-surgery claim for this service. Co-surgeon and team-surgery reporting are not permitted.
