Coverage Criteria and High-Level Stances

Modality-level coverage stance

High-level coverage stance by modality as stated in this document

Implanted Peripheral Nerve Stimulation: Implanted peripheral nerve stimulation is covered when criteria are met; refer to the NCD for Electrical Nerve Stimulators (160.7).

Specific criteria not included in this partial document.

Electrical Stimulation of Auricular Acupuncture Points: No Medicare NCD exists; LCDs/LCAs have retired — refer to UnitedHealthcare Commercial Medical Policy titled Electrical Stimulation for the Treatment of Pain and Muscle Rehabilitation for coverage guidelines.

Local LCDs/LCAs retired per policy update.

Electrical Stimulation for Dysphagia: No Medicare NCD; LCDs/LCAs exist and compliance with these is required where applicable; refer to the table for specific LCDs/LCAs or to the UnitedHealthcare Commercial Medical Policy where none apply.

Specific LCD/LCA references listed in CMS Related Documents table.

Occipital Nerve Stimulation: No Medicare NCD; LCDs/LCAs exist and compliance is required where applicable; refer to the provided table or to UnitedHealthcare Commercial policy for states/territories without LCDs/LCAs.

Coverage guidance cross-references Occipital Nerve Injections and Ablation policy.

Percutaneous Peripheral Nerve Stimulation and PENS/PNT: No Medicare NCD for PENS/PNT; LCDs/LCAs for percutaneous PNS exist and compliance is required where applicable; refer to provided tables or UnitedHealthcare Commercial policy when none exist.

Vagus Nerve Stimulation for Chronic Pain: No Medicare NCD; refer to UnitedHealthcare Commercial Medical Policy titled Vagus and External Trigeminal Nerve Stimulation for coverage guidelines.

The list of procedure and diagnosis codes in this policy is provided for reference only. Listing of a code in this policy does not imply that the service described by the code is a covered health service; benefit coverage and reimbursement are determined by the member-specific benefit plan document and applicable laws, and inclusion of a code does not guarantee payment or create a right to reimbursement.

This policy is informational and does not replace the member-specific benefit plan document. Services excluded by the member plan are not covered despite this policy; in the event of any conflict, the member-specific benefit plan document supersedes this Medicare Advantage policy. For questions about a member's coverage, contact the customer service number on the member ID card or refer to the Administrative Guide.

This partial Medicare Advantage policy references CMS materials (NCDs, LCDs, LCAs) where applicable but does not itself declare specific services as not medically necessary. Coverage determinations depend on applicable NCDs, LCDs, LCAs, and the member’s benefit plan; where local CMS guidance applies, providers should follow that guidance and the referenced documents for definitive coverage direction.

Provider Responsibilities and Operational Instructions

Note

Coverage Dependency on Plan and CMS Documents

Coverage and reimbursement for services described in this policy depend on the member-specific benefit plan document and applicable Medicare/CMS guidance. The listing of codes or references in this policy is for informational purposes only and does not guarantee coverage or payment. In the event of a conflict between this policy and a member's benefit plan, the member-specific benefit plan document supersedes this policy. For questions about a specific member's coverage, contact the customer service number on the back of the member ID card or refer to the Administrative Guide.

Benefit coverage is determined by the member-specific benefit plan and applicable laws/CMS guidance.
Listing of codes in this policy is for reference and does not guarantee coverage or reimbursement.
If there is a conflict, the member-specific benefit plan document governs.

Documentation Required

Medical Record Documentation and Retention

Providers are expected to retain or have timely access to appropriate medical records and documentation to support coverage and medical necessity determinations. Documentation should be made available upon request to UnitedHealthcare or its delegates and should follow applicable Medicare and payer documentation standards.

Policy Background and Scope

This Medicare Advantage policy compiles applicable CMS guidance (National Coverage Determinations, Local Coverage Determinations, Local Coverage Articles) and cross-references UnitedHealthcare commercial policy where CMS materials do not apply. It is intended to support UnitedHealthcare coverage decisions for multiple electrical stimulation modalities used to treat pain, dysphagia, and functional impairment; providers must retain appropriate documentation and follow applicable CMS guidance and member benefit plan provisions when determining medical necessity.

Imaging Requirements

Note

Imaging requirements — check modality-specific guidance

No specific imaging requirements are stated in this portion of the Policy; consult modality-specific sections, referenced CMS LCDs/LCAs, or related UnitedHealthcare policies for any imaging prerequisites.

When applicable LCDs/LCAs exist, follow their imaging requirements.
Refer to modality-specific tables or UnitedHealthcare commercial policies where no Medicare source applies.

Not Covered / Exclusions

In this partial document there are no explicitly stated procedural items labeled as not covered. The inclusion of codes or procedures in the policy does not, by itself, indicate coverage or non-coverage; benefit determinations are made based on applicable CMS guidance and the member-specific benefit plan.
