# CPT 17311

> Medicare paid $674.35 for CPT 17311 in the office (non-facility) setting and $392.62 in a facility under the Q2 2017 Physician Fee Schedule, effective April 2017. These are the national allowed amounts before the ~2% sequestration cut and before locality (GPCI) adjustment. This price has been unchanged since Q1 2017, when it increased 0.6%.

## What it is

The first round of Mohs micrographic surgery on the head, neck, hands, feet, genitals, or other functionally sensitive sites, where a single physician acts as both surgeon and pathologist. A thin layer of the tumor is removed, mapped, frozen, and examined under the microscope while the patient waits, so the exact edges where cancer remains can be identified. This code covers that first layer and the limited number of tissue blocks that go with it; further rounds and extra blocks are counted separately, and the same work on the trunk and limbs uses a different code.
