Muscle-Relaxing Injection Into the Anal Muscle

Vermont rates for HCPCS 46505

Injection of a muscle-relaxing medicine, usually botulinum toxin, into the inner ring of muscle around the anus so it stops gripping so tightly. Easing that spasm improves blood flow to the area and lets a painful tear in the anal lining heal. The effect wears off over a few months, by which time healing has usually happened.
