About 11600: Small malignant lesion excision, trunk or extremity
Reports excision of a malignant skin lesion on the trunk, arm, or leg when the lesion and required margins have an excised diameter of 0.5 cm or less.
This code describes removal of a malignant skin lesion from the trunk, an arm, or a leg, with margins included in the measured excision. Dermatologists, surgeons, and other qualified clinicians may perform it in an office procedure room or a facility. The size category is based on the lesion’s greatest clinical diameter plus the margins taken, not just the visible lesion. Typical cases include excision of a small malignant lesion on the back, torso, or extremity.
Report the code when the excised diameter is 0.5 cm or less and the site falls within this anatomic group. Documentation should identify the site, lesion dimensions, margins or excised diameter, and clinical or pathology support for malignancy. Simple closure is included; a separately documented intermediate or complex repair may be reported under its repair code. The procedure has a 10-day global period, including related postoperative visits during that period. When multiple procedures occur in one session, the highest-valued is paid in full and other procedures are subject to the standard 50% reduction. Modifier 50 is inappropriate; assistant-at-surgery payment is restricted, and co-surgeon and team-surgery billing are not permitted.

11600 billing questions
How do I distinguish this code from 11601?
Use 11600 when the lesion plus required margins measures 0.5 cm or less. Code 11601 begins at an excised diameter of 0.6 cm.
Does the measurement include the margins?
Yes. Select the size category using the lesion’s greatest clinical diameter plus the margins removed, rather than the lesion alone.
Can I bill separately for closing the excision?
Simple closure is included in the excision. A separately documented intermediate or complex repair may be reported when the repair service meets its code requirements.
Can modifier 50 be used for lesions on both sides?
No. Modifier 50 is inappropriate for this code. The CMS bilateral adjustment does not apply.
Are assistant or co-surgeon services payable?
Assistant-at-surgery payment is restricted for this code. Co-surgeons and team surgery are not permitted.
Are related postoperative visits included?
Yes. The 10-day global period includes related postoperative visits during those 10 days.
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.
