# CPT 00124

> CPT 00124 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 $176.37 for a 60-minute case in Dallas, TX under the Q1 2018 release, before sequestration.

## What it is

Anesthesia care for a close examination of the ear canal and eardrum done under anesthesia rather than in the office, most often because the patient - typically a young child - cannot hold still for the exam awake. It is a brief anesthetic for a diagnostic look, not an operation, which is what separates it from the ear-surgery and ear-tube anesthesia codes nearby.
