# CPT 00170

> CPT 00170 is an anesthesia code, so Medicare has no single national rate: payment is (base units + time units) × the locality's anesthesia conversion factor — for example, about $191.41 for a 60-minute case in Dallas, TX under the Q1 2021 release, before sequestration.

## What it is

Anesthesia care for surgery inside the mouth, including biopsy, when no more specific intraoral-anesthesia code applies - the general entry for this region, distinct from the dedicated codes nearby for cleft palate repair, removal of a tumor behind the throat, or more extensive intraoral surgery. It covers procedures such as removal of a mouth lesion or a biopsy of oral tissue.
