What 17266 covers

This code covers destruction of a malignant skin lesion larger than 4.0 cm on the trunk, an arm, or a leg. Dermatologists and other clinicians who treat skin cancers may use destructive techniques such as electrosurgery, cryosurgery, laser treatment, or curettage with electrosurgical destruction. It is selected for the treated lesion’s anatomic site and size, not simply for the diagnosis or method used.

Document the lesion’s location, measured size, malignant diagnosis, and the destruction performed. Report the code for each treated lesion that meets its site and size criteria. The service has a 10-day global period, so related postoperative visits during that period are included. 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 multiple-procedure reduction. Modifier 50 is inappropriate. Medicare does not pay an assistant at surgery for this service; co-surgeons and team surgery 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.

17266 billing questions

When should I choose this code instead of 17264?

Use 17266 for a malignant lesion on the trunk, arm, or leg that measures more than 4.0 cm. Code 17264 is for the same site group when the lesion measures 3.1 to 4.0 cm.

Does the code depend on the destruction method?

Selection depends on the malignant lesion’s site and size. Document the technique performed, such as cryosurgery or electrosurgical destruction, along with the lesion details.

Can I append modifier 50 for lesions on both sides?

No. CMS identifies bilateral adjustment as inappropriate for this code. Report qualifying lesions according to the applicable site and size criteria.

Are related postoperative visits separately reported?

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

How does Medicare handle multiple procedures in the same session?

The highest-valued procedure is paid in full, and other procedures are subject to the standard multiple-procedure reduction. This code also cannot be reported with an assistant at surgery, co-surgeons, or team surgery.

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.
