What 17111 covers

This service covers destruction of 15 or more benign skin lesions in a treatment session, using methods such as cryotherapy, electrosurgery, chemical treatment, laser, or curettage. Dermatologists, primary care clinicians, and other qualified practitioners commonly treat lesions such as common warts and seborrheic keratoses in office settings. Skin tags and cutaneous vascular proliferative lesions are outside this code’s lesion group.

Select this code when the total number of eligible lesions treated reaches 15; for 14 or fewer, consider 17110. Document the lesion count, clinical findings, locations, and treatment performed. Medicare assigns a 10-day global period, so related postoperative visits during that period are included. When multiple procedures occur 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 service, and co-surgeon and team-surgery reporting 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.

Use 17111 when 15 or more eligible benign lesions are destroyed in the session. Use 17110 for 14 or fewer.

Do skin tags count toward the lesion total?

No. Skin tags are excluded from this code’s lesion group and are reported with the applicable skin-tag removal code.

Should I report one unit for each lesion?

No. The code is selected by the total number of eligible lesions treated in the session: 15 or more, rather than one unit per lesion.

Can I append modifier 50?

No. CMS identifies bilateral adjustment as inappropriate for this code.

Are related postoperative visits separately payable during the global period?

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

How does Medicare handle another procedure performed in the same session?

Under the standard multiple-procedure reduction, the highest-valued procedure is paid in full and other procedures are paid at 50% when performed in the same session.

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.
