Submitting Radiofrequency Ablation (RFA) Requests

Radiofrequency (RFA) is a procedure that uses radio waves to stop the nerve from transmitting pain signals from the facet joint to the brain. Click the section below to learn more information related to HOW you should enter these types of requests in the Cohere platform.
