Question 1. Our physician performed these two techniques together for patient suffering w/ TGN.. We use CPT code 64610. Would this be the correct?

Percutaneous Glyceral Rhiztomy utilizes glycerol injected through a needle into the area where the nerve divides into three main branches.

Percutaneous Balloon compression utilizes a needle that is passed through the cheek to the trigeminal nerve. The neurosurgeon places a balloon in the trigeminal nerve through a catheter. The balloon is inflated where fibers produce pain. The balloon compressed the nerve ,injuring the pain-causing fibers. After several minutes, the balloon and catheter are removed.
