Medicare allowed amount for participating (non-QP) physicians, before deductible, coinsurance and claim adjustments. Not a patient’s bill or a hospital charge.

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.
