What 17313 covers

A Mohs surgeon removes a skin cancer in mapped tissue layers, processes and examines the tissue microscopically, and uses the findings to guide further removal while preserving uninvolved tissue. This code represents the first stage for a lesion on the trunk, an arm, or a leg. It is commonly used for cutaneous basal cell or squamous cell carcinomas treated in a dermatology office or hospital outpatient setting.

Report one first-stage service for the treated site, with the number of tissue blocks documented; the first stage includes up to five blocks. Record the anatomic site, mapping, blocks examined, and histologic findings. Additional stages are reported with 17314, and additional blocks beyond the included amount with 17315. Same-day preoperative and postoperative care is included in the 0-day global period. When other procedures are performed in the same session, the highest-valued procedure is paid in full and the others are subject to the standard multiple-procedure reduction. Modifier 50 is inappropriate. Medicare does not pay an assistant at surgery; 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.

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.
