Summary & Overview
CPT 64566: Percutaneous Posterior Tibial Nerve Stimulation
CPT code 64566 denotes percutaneous posterior tibial nerve stimulation: insertion of a needle electrode through the skin to deliver electrical stimulation to the posterior tibial nerve. This targeted neuromodulation procedure is used for conditions involving lower-extremity nerve modulation and carries growing clinical relevance as minimally invasive neuromodulation expands. Nationally, accurate coding for 64566 affects coverage determination, site-of-service planning, and billing consistency for outpatient neuromodulation services.
Key payers included in this analysis are Aetna, Blue Cross Blue Shield, Cigna Health, UnitedHealthcare, and Medicare. Readers will find benchmarking context for coverage and coding practices, a concise clinical description of the procedure and typical sites of service, and a summary of common billing modifiers and coding considerations when present. The publication also outlines what information is available and notes areas where input data is not provided.
This summary equips billing and compliance leaders, clinicians who perform neuromodulation, and revenue-cycle staff with a clear, national-level reference for CPT code 64566, emphasizing clinical intent, service setting, and payer considerations relevant to coding and claims processing.
Billing Code Overview
CPT code 64566 describes a procedure in which a provider applies electrical stimulation to the posterior tibial nerve by inserting a needle electrode through the skin. The procedure is a targeted neuromodulation technique used to modulate nerve activity in the lower extremity.
Service type: Percutaneous posterior tibial nerve stimulation.
Typical site of service: Outpatient procedure area, ambulatory surgery center, or clinic setting where minimally invasive nerve stimulation procedures are performed.
Data not available in the input.
Clinical & Coding Specifications
Clinical Context
A typical patient is an adult with refractory overactive bladder or neurogenic bladder symptoms who has failed or is intolerant of conservative therapies (behavioral therapy, oral medications). The patient presents to an outpatient ambulatory surgery center or clinic procedure room for percutaneous posterior tibial nerve stimulation using a sterile single-use needle electrode. After informed consent, the patient is positioned supine with the lower leg and ankle exposed. The posterior tibial nerve is identified just above the medial malleolus by palpation and anatomical landmarks. A thin needle electrode is inserted through the skin toward the nerve and connected to an external stimulator. Current is titrated to elicit sensory and/or motor responses without pain. Typical treatment is a series of stimulation sessions lasting about 30 minutes each. Monitoring includes vital signs, skin integrity at the insertion site, and patient-reported sensation. The procedure is commonly performed under local anesthesia only; general anesthesia is uncommon. Post-procedure instructions include monitoring the puncture site for bleeding or infection and activity limitations for a short period.
