What 11601 covers
This service removes a malignant skin lesion from the trunk, an arm, or a leg, including the surrounding margins. A dermatologist, surgeon, or other qualified physician typically performs the excision in an office or outpatient setting. The selected size is the greatest diameter of the lesion plus the margins, not the lesion’s diameter alone. Routine simple closure is included; a separately documented intermediate or complex repair may be reported when its requirements are met.
Report this code for an excised diameter of 0.6–1 cm at one of these anatomic sites. Documentation should identify the site, lesion dimensions, margins taken, final excised diameter, and malignant diagnosis. The 10-day global period includes related postoperative visits during that period. When multiple procedures are performed in the same session, the highest-valued procedure is paid in full and other procedures are subject to the standard 50% reduction. Modifier 50 is inappropriate. Medicare does not pay an assistant at surgery for this code; co-surgeons and team surgery are not permitted.

11601 billing questions
How is the size range determined?
Use the greatest diameter of the lesion together with the margins removed. The lesion’s original diameter alone does not determine the code.
When should 11600 or 11602 be reported instead?
For a trunk, arm, or leg lesion, use 11600 when the excised diameter is 0.5 cm or less and 11602 when it is 1.1–2 cm.
Can the closure be billed separately?
Routine simple closure is included. A separately documented intermediate or complex repair may be reported when the repair meets that service’s coding requirements.
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.
What documentation supports reporting 11601?
Record the anatomic site, lesion dimensions, margins removed, greatest final excised diameter, and malignant diagnosis.
Are postoperative visits included?
Related postoperative visits during the 10-day global period are included in the procedure payment.
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.
