What 11602 covers

This service removes a malignant skin lesion from the trunk or an extremity, including the margins taken to achieve excision. Dermatologists and surgeons commonly perform it in an office or outpatient facility for cancers such as basal cell or squamous cell carcinoma. The code’s size range is based on the lesion’s greatest diameter together with the narrowest margins removed, not the length of the final closure.

Select the code using the anatomic site and documented excised diameter. The record should identify the lesion site, malignancy, lesion dimensions, margins, and resulting excised diameter. Simple closure is included; a separately documented intermediate or complex repair may be reported when its criteria are met. The 10-day global period includes related postoperative visits during that period. When multiple procedures occur in the same session, the highest-valued procedure is paid in full and other procedures are subject to the standard multiple-procedure reduction. Modifier 50 is inappropriate. Medicare does not pay for an assistant at surgery, and co-surgeon and team-surgery billing are not permitted.

This summary was written with AI assistance from CMS physician fee schedule data and checked against the CMS billing rules shown here. Rates on this page come directly from CMS files.

11602 billing questions

How do I choose between 11602 and 11601 or 11603?

Use 11602 when the lesion plus the margins removed measures 1.1–2 cm. The adjacent codes cover the smaller and larger size ranges, respectively.

Does the code depend on the closure length?

No. Select the excision code by the lesion and margins removed. Simple closure is included; a qualifying intermediate or complex repair may be separately reported based on the repair performed and its documented length.

Can modifier 50 be used for lesions on both sides?

No. CMS identifies bilateral adjustment as inappropriate for this code. Report the services according to the applicable lesion and procedure coding.

What documentation supports the 1.1–2 cm level?

Document the malignant diagnosis, exact site, lesion dimensions, margins removed, and excised diameter. The excised diameter includes the lesion and the margins, rather than the closure length.

Are postoperative visits included?

Related postoperative visits during the 10-day global period are included in the procedure.

How does Medicare handle multiple procedures in one session?

The highest-valued procedure is paid in full, and other procedures performed in the same session are subject to the standard multiple-procedure reduction.

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.
