What is the cost of facet rhizotomy?

At least 800$: This depends greatly on the location where the procedure is done. A pain specialist with the ability to do it in his office with minimal sedation will likely charge you around 800$ if paying cash. If you do it in a surgery center with more sedation expect to spend a couple of thousand, and more like 5 thousand if it is done in a hospital. If you have insurance how much you pay will vary with plan.

Varies: Depends on location and provider. Get quotes from your pain anesthetist.

Costs Vary: Depends on where its done and which part of the country you are in. Office based treatments are much cheaper than going to a surgical center or hospital.
