# CPT 00174

> CPT 00174 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 $219.88 for a 60-minute case in Dallas, TX under the Q1 2020 release, before sequestration.

## What it is

Anesthesia care for surgery to remove a tumor from the retropharyngeal space, the area behind the throat near the top of the spine. This is a more involved intraoral anesthesia case than routine mouth surgery, working near major blood vessels and close to the airway itself.
