# CPT 00212

> CPT 00212 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 $462.62 for a 240-minute case in Dallas, TX under the Q1 2016 release, before sequestration.

## What it is

Anesthesia care for a subdural tap, a procedure that drains fluid or blood collected just beneath the skull, most often performed in infants through the soft spot before the skull bones have fused. It is a much less invasive procedure than a full craniotomy, and in infants may be done with minimal or no anesthesia beyond local numbing, though anesthesia support is used when the patient needs to be kept still and calm.
