Posterior Tibial Nerve Stimulation for Voiding Dysfunction
Defines medical necessity criteria for percutaneous posterior tibial nerve stimulation (PTNS) for treatment of overactive bladder (OAB), including initial and maintenance therapy, and states that implantable tibial nerve stimulation is not supported by evidence. Provides applicable CPT coding guidance.
Replaced 'investigational' language with 'insufficient evidence to support' in statements regarding use beyond 12 months and implantable devices.
Updated CPT coding guidance to list 64566 as supporting medical necessity and T-codes (0587T–0590T) as not supporting medical necessity.
