# CPT 01402

> CPT 01402 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 $270.95 for a 90-minute case in Dallas, TX under the Q2 2024 release, before sequestration.

## What it is

Anesthesia care for open surgery on the knee joint, including total knee replacement. It is typically delivered as a spinal anesthetic with sedation or as general anesthesia, very often combined with a nerve block or injection around the knee so the patient can start physical therapy soon after. This code covers the open joint operation, in contrast to the anesthesia codes used for arthroscopic keyhole knee procedures.
