# CPT 00300

> CPT 00300 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 $241.94 for a 90-minute case in Dallas, TX under the Q4 2017 release, before sequestration.

## What it is

Anesthesia care for operations on skin, underlying soft tissue, muscles and nerves of the head, neck, or the back of the trunk, when no more specific anesthesia code fits the case. It is the catch-all entry for surface and soft-tissue work in that region, as opposed to codes tied to a named structure such as the eye, airway or spine itself. Examples of the surgery it accompanies include removal of a large skin lesion on the scalp or back, drainage of a deep neck abscess, or a soft-tissue mass excision.
