This policy defines medical necessity, coding, and prior authorization expectations for percutaneous tibial nerve stimulation (PTNS) and subcutaneous/implantable tibial nerve stimulation for treatment of voiding dysfunction and overactive bladder for BCBSRI Medicare Advantage and Commercial products.
No material clinical or coverage changes in this revision.
Coverage Criteria for Tibial Nerve Stimulation
Initial PTNS therapy (Medicare Advantage and Commercial when criteria met)
Percutaneous tibial nerve stimulation (PTNS) is considered reasonable and necessary when ALL of the following are met:
Maintenance PTNS
Maintenance and retreatment rules:
Optimal regimen unclear; observational data support benefit for some patients
Not Medically Necessary / Insufficient Evidence
Not covered / insufficient evidence conditions:
Applies to Medicare Advantage and Commercial Products
General coverage condition
Covered when ALL of the following are met (summary from provided text):
Detailed clinical inclusion/exclusion criteria are specified elsewhere in the policy and the web-based tool.
Subcutaneous or implantable tibial nerve stimulation systems (for example, eCoin) and procedures involving open subcutaneous insertion/replacement identified by CPT code 0816T are not covered / not medically necessary for all indications, including treatment of non‑neurogenic urinary dysfunction such as overactive bladder. The available evidence is insufficient to demonstrate improvement in net health outcome for these implantable subcutaneous systems.
Procedure coding with 0816T (Open insertion or replacement of integrated neurostimulation system for bladder dysfunction … posterior tibial nerve; subcutaneous) is explicitly listed as not covered for Medicare Advantage Plans and not medically necessary for Commercial Products. Providers submitting claims for open subcutaneous posterior tibial neurostimulation should not expect coverage under this policy.
Implantable subcutaneous tibial nerve stimulation systems are considered not covered / not medically necessary because the evidence is insufficient to determine that these technologies improve net health outcomes for indications including non‑neurogenic urinary dysfunction and overactive bladder. This rationale applies to both Medicare Advantage and Commercial products.
Note on coding: CPT code 0816T describes open insertion or replacement of an integrated neurostimulation system for bladder dysfunction including electrode(s) and pulse generator or receiver, with analysis, programming, and imaging guidance when performed, specified for the posterior tibial nerve and described as subcutaneous. Under this policy, services reported with 0816T are designated not covered / not medically necessary.

Provider Actions, Authorization, and Documentation
Prior authorization required (Medicare Advantage); recommended for Commercial
Prior authorization is required for Medicare Advantage Plans via the online tool; it is recommended (not required) for Commercial Products for CPT 64566 and 0587T. Providers should use the web-based prior authorization tool for participating providers as directed in related policies.
Use web-based prior authorization tool for Medicare Advantage
For Medicare Advantage Plans, prior authorization via the web-based tool is required for the listed CPT/HCPCS codes and referenced procedures; commercial products require that policy criteria be met (prior authorization is recommended). Providers must follow the online tool for participating providers.
Conservative therapy prerequisites: behavioral therapy and 2 medication trials (4–8 wks)
Before PTNS is considered reasonable and necessary, the member must have failed symptom-appropriate behavioral therapy and have failed or been unable to tolerate a trial of at least two appropriate medications administered for 4–8 weeks each.
- Behavioral therapy must be of sufficient length to evaluate efficacy and documented in the medical record.
- Each of at least two appropriate medications must be administered for four (4) to eight (8) weeks.
Verify conservative therapy, documentation, and member benefits before requesting authorization
Providers must confirm that the patient has met all conservative therapy prerequisites and that medical necessity criteria are met in the web-based prior authorization tool prior to requesting coverage; verify member-specific benefits and eligibility with the plan.
- Confirm documentation of behavioral therapy failure and two medication trials of 4–8 weeks each.
- Use the web-based prior authorization tool for Medicare Advantage and follow related policy guidance.
- Verify member benefits and eligibility with the provider call center if needed.
Required clinical documentation to support medical necessity
Providers must obtain and retain required clinical documentation demonstrating that medical necessity criteria are met before PTNS is provided. Documentation must include specialist evaluation, behavioral therapy and medication trial records, voiding diaries, and documented willingness to participate in treatment.
- Specialist evaluation by an appropriate specialist (usually a urologist or urogynecologist).
- Medical record documents compliance with and failure of symptom-appropriate behavioral therapy.
- Records showing failure or intolerance of at least two appropriate medications (each 4–8 weeks).
- Voiding diaries demonstrating ongoing overactive bladder syndrome.
- Documentation of the beneficiary’s willingness to attend in‑office sessions, comply with behavioral therapies, and continue voiding diaries.
Ensure codes meet policy criteria and verify member benefits via web-based tool
Coverage determinations reference that CPT/HCPCS codes are medically necessary when policy criteria are met; providers should follow the web-based prior authorization tool and verify member-specific benefits and eligibility.
Denial risk: not obtaining required Medicare Advantage prior authorization
Failure to obtain prior authorization for Medicare Advantage Plans via the online tool (required) may result in denial of payment.
- Required for Medicare Advantage: use the online tool for participating providers.
- If services are denied as not medically necessary or prior authorization was not obtained, providers may not bill the member unless the member was informed and agreed in writing.
Denial risk: services not medically necessary or non‑covered
Services determined to be not medically necessary, or medically necessary services that are non‑covered benefits (for example CPT 0816T), may result in the provider not being able to charge the member unless the member was informed and agreed in writing to pay.
- 0816T (open subcutaneous insertion/replacement) is listed as not covered/not medically necessary.
- If a service is determined not medically necessary, providers must follow participation agreements and obtain member consent in writing before billing the member.
Background and Context
Percutaneous tibial nerve stimulation (PTNS) is an electrical neuromodulation technique used primarily to treat non‑neurogenic voiding dysfunction and overactive bladder. The procedure involves insertion of a percutaneous needle electrode near the posterior tibial nerve (typically above the medial malleolus) with low‑voltage electrical stimulation producing sensory and motor responses. The recommended initial regimen is an office‑based course of one 30‑minute session per week for 12 weeks, with maintenance treatments typically individualized and often scheduled every 4–6 weeks following response to the initial course.
Definitions and Terminology
Conservative Treatment Preconditions
Mandatory before PTNS is reasonable and necessary
Mandatory before PTNS is reasonable and necessary:
Document duration and response for each medication
Providers should confirm member-specific benefits and that other conservative/alternative treatments and medical necessity criteria are met per the policy and web-based tool (implied)
Providers should confirm member-specific benefits and that other conservative/alternative treatments and medical necessity criteria are met per the policy and web-based tool.
Failure to obtain required prior authorization for Medicare Advantage may result in denial

Treatment Frequency and Limits
Imaging Considerations
Code 0587T for percutaneous implantation when indicated
Use CPT code 0587T for percutaneous implantation or replacement of an integrated single‑device neurostimulation system for bladder dysfunction (posterior tibial nerve) when performing percutaneous implantation as indicated.
- 0587T includes analysis, programming, and imaging guidance when performed.
Report 0587T when percutaneous implantation is performed
When performed, report CPT code 0587T for percutaneous implantation or replacement of an integrated single‑device neurostimulation system for bladder dysfunction involving the posterior tibial nerve.
- Ensure documentation supports implantation and use of device components, analysis, and programming.
Not Covered / Exclusions
NOT COVERED: Subcutaneous/implantable tibial nerve stimulation systems (for example, eCoin) and open insertion/replacement procedures billed with CPT 0816T are not covered / not medically necessary for treatment of non‑neurogenic overactive bladder and related indications for both Medicare Advantage and Commercial Products under this policy.
