# CPT 00790

> CPT 00790 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 $517.96 for a 240-minute case in Dallas, TX under the Q3 2015 release, before sequestration.

## What it is

Anesthesia care for operations inside the abdominal cavity in its upper half, whether done through an open incision or laparoscopically, when no more specific anesthesia code applies. It is the general-purpose entry for that region, distinct from codes tied to a named organ or to the lower abdomen. Surgeries it accompanies include gallbladder removal, stomach and hernia repairs at the upper abdomen, and exploratory laparotomy.
