Defines medical necessity, coverage criteria, and coding guidance for percutaneous posterior tibial nerve stimulation to treat overactive bladder (OAB) and related voiding dysfunction for Arizona Complete Health members.
Replaced 'investigational' language with 'insufficient evidence to support' for certain uses of PTNS and implantable tibial nerve stimulation.
Clarified conservative management examples to include behavioral therapies such as bladder training and pelvic floor muscle training and broadened medication language to 'medications used with the intent to treat OAB.'
Updated coding and descriptions and removed ICD-10 CM Diagnosis Code table.
Coverage and Medical Necessity Criteria
Initial PTNS Therapy
Covered when ALL of the following are met:
Responders often show some improvement after 6-8 sessions.
Maintenance PTNS Therapy
Covered when ALL of the following are met:
Limitations on Duration and Use
Implantable tibial nerve stimulation devices currently have limited evidence to support their use for voiding dysfunction.
Claims submitted with CPT codes for implantation, revision/removal, or programming of implantable posterior tibial nerve stimulation systems are not supported by evidence and are not covered under this policy. Examples of CPT codes that do not support medical necessity include 0587T, 0588T, 0589T, and 0590T. Providers billing these codes risk denial.
There is insufficient evidence to support the use of posterior tibial nerve stimulation beyond 12 months or the use of implantable tibial nerve stimulation devices for urinary voiding dysfunction. Implantable tibial nerve neuromodulation systems are currently under investigation and available published evidence is limited; therefore use of PTNS beyond one year or implantation of tibial nerve systems is considered not supported by the evidence in this policy.
Coding Guidance
| 64566 | Posterior tibial neurostimulation, percutaneous needle electrode, single treatment, includes programming |
| 0587T | Percutaneous implantation or replacement of integrated single device neurostimulation system for bladder dysfunction including electrode array and receiver or pulse generator, including analysis, programming and imaging guidance when performed, posterior tibial nerve. |
| 0588T | Revision or removal of percutaneously placed integrated single device neurostimulation system for bladder dysfunction including electrode array and receiver or pulse generator, including analysis, programming, and imaging guidance when performed, posterior tibial nerve. |
| 0589T | Electronic analysis with simple programming of implanted integrated neurostimulation system for bladder dysfunction (eg, electrode array and receiver), including contact group(s), amplitude, pulse width, frequency (Hz), on/off cycling, burst, dose lockout, patient-selectable parameters, responsive neurostimulation, detection algorithms, closed-loop parameters, and passive parameters, when performed by physician or other qualified health care professional, posterior tibial nerve, 1-3 parameters. |
| 0590T | Electronic analysis with complex programming of implanted integrated neurostimulation system for bladder dysfunction (eg, electrode array and receiver), including contact group(s), amplitude, pulse width, frequency (Hz), on/off cycling, burst, dose lockout, patient-selectable parameters, responsive neurostimulation, detection algorithms, closed-loop parameters, and passive parameters, when performed by physician or other qualified health care professional, posterior tibial nerve, 4 or more parameters. |
Provider Requirements and Billing Actions
Prior Authorization and Supported Codes
Prior authorization is required per plan rules for posterior tibial nerve stimulation (PTNS) services. Claims billed with CPT 64566 (posterior tibial neurostimulation, percutaneous needle electrode, single treatment, includes programming) require prior authorization. Implantable tibial nerve stimulation system procedure and device codes (CPT 0587T–0590T) are not supported and should not be authorized.
- Prior authorization required for CPT 64566
- CPT 0587T–0590T are not supported / not covered
Conservative Management Required Before PTNS
Before initiating PTNS, providers must document failure of conservative medical management for overactive bladder (OAB) unless such measures are not desired by the patient or are medically contraindicated. Conservative management includes behavioral therapies (e.g., bladder training, pelvic floor muscle training) and pharmacotherapy with oral medications commonly used to treat OAB. Documentation of prior conservative therapies and the patient's response (or contraindication) must be included in the medical record.
- Documented failure of behavioral therapies (bladder training, pelvic floor muscle training) OR contraindication to these therapies
- Documented trial and failure of pharmacotherapy for OAB OR contraindication to medications
- If conservative management was not attempted due to patient preference or medical contraindication, documentation must state the reason
Definitions
Background
Overactive bladder (OAB) is a voiding dysfunction characterized by urinary urgency, frequency, urge incontinence, and nocturia that can impair quality of life. Posterior tibial nerve stimulation (PTNS) is a minimally invasive neuromodulation technique that delivers electrical stimulation to the posterior tibial nerve near the ankle (via a percutaneous needle electrode and a surface electrode on the foot) to indirectly modulate sacral nerves controlling bladder function. Typical stimulation parameters reported in the literature are 0.5–9 mA at 20 Hz for 30 minutes per session. Initial treatment regimens generally consist of 12 weekly 30-minute sessions, with some patients showing improvement after 6–8 sessions; maintenance sessions may be required, commonly delivered about once monthly for responders.
