Dermatologic surgery
About 11624: Malignant skin lesion excision, specialized sites
Reports excision of a malignant skin lesion on the scalp, neck, hands, feet, or genitalia when the lesion and margins span 3.1–4 cm.
A dermatologist or surgeon uses this code to remove a malignant skin lesion from the scalp, neck, hands, feet, or genitalia. Common examples include excision of basal cell carcinoma, squamous cell carcinoma, or melanoma. The size category is based on the excised diameter: the lesion together with the margins removed around it, not the lesion’s size alone. The service may be performed in an office, ambulatory surgery center, or hospital setting.
Document the exact site, lesion dimensions, margins taken, and resulting excised diameter; pathology records can support the malignant diagnosis. Simple closure is included, while a separately reportable intermediate or complex repair may be coded when performed and documented. Medicare includes related postoperative visits for 10 days in the global period. When multiple procedures are performed in one session, the highest-valued procedure is paid in full and others are subject to the standard 50% reduction. Modifier 50 is inappropriate. Medicare does not pay an assistant at surgery, and co-surgeon and team-surgery billing are not permitted.

11624 billing questions
How is the 3.1–4 cm size determined?
Use the excised diameter, which includes the lesion and the margins removed around it. Document the lesion, margins, and total excised measurement.
Which body sites belong to this code?
It applies to malignant lesions on the scalp, neck, hands, feet, or genitalia. Similar-sized lesions on the trunk, arms, or legs use a different code family.
Is closure separately billable?
Simple closure is included in the excision. A separately documented intermediate or complex repair may be reported when performed.
Can modifier 50 be used for lesions on both sides?
No. CMS identifies bilateral adjustment as inappropriate for this code; do not use modifier 50.
What postoperative care is included?
Related postoperative visits during the 10-day global period are included in the procedure.
How are other procedures in the same session paid?
Under the standard multiple procedure reduction, the highest-valued procedure is paid in full and the other procedures are paid at 50%. Medicare also does not pay an assistant at surgery or permit co-surgeon or team-surgery billing for this code.
Where these rates come from
FeeBase calculates base physician payments from CMS work, practice-expense, and malpractice RVUs, adjusted by each locality’s geographic indices and the applicable conversion factor. Unavailable or separately priced services are labeled rather than assigned a made-up amount.
