Monitor payer policy activity
This draft policy governs coverage of remote electrical neuromodulation (REN) devices (e.g., Nerivio) for acute and preventive treatment of migraine for Medicare Advantage and commercial products under Blue Cross Blue Shield - Rhode Island.
No material clinical or coverage changes in this revision.
Coverage Criteria
Covered indication
Covered when ALL of the following are met:
The Nerivio remote electrical neuromodulation device is contraindicated in patients with uncontrolled epilepsy and in patients with an active implantable medical device (for example, pacemaker, hearing aid implant, or any implanted electronic device). The device has not been evaluated in certain high-risk groups, including patients with congestive heart failure, severe cardiac or cerebrovascular disease, pregnancy, or children under 8 years of age.
This portion of the policy does not present additional explicit coverage criteria or exclusions beyond the device contraindications and regulatory history. It contains references and administrative notes clarifying that member benefits and eligibility are determined by the subscriber agreement or employer agreement and that providers should contact the provider call center for member-specific determinations.
The policy lists both Medical Criteria and Prior Authorization as Not applicable, indicating there are no additional medical necessity criteria or prior authorization requirements specified in this draft for REN.
Services determined to be not medically necessary or otherwise non-covered may not be charged to the member unless the provider has informed the member and the member has provided written agreement to proceed at their own expense. Providers should consult participation agreements and the member's subscriber documents for applicable provisions.

Provider Actions and Administrative Requirements
Prior authorization — Not applicable
Prior authorization: Not applicable for REN (Nerivio) for chronic migraine under Medicare Advantage and Commercial products.
- Covered HCPCS code listed: A4540 (see coding section).
Prior authorization: verify with payer
Verify member-specific benefit determinations and prior authorization requirements with the payer before providing REN; this document does not specify explicit prior authorization steps and benefits are governed by the member's contract.
- Contact the provider call center for member-specific benefits and eligibility.
- Participation agreements and subscriber agreements supersede this policy.
Step therapy — none specified
No step therapy requirements are specified in this policy; REN (Nerivio) may be used as an alternative to pharmacologic interventions per device labeling.
- REN can be used instead of or in addition to medication per device labeling.
- Document clinical rationale when choosing REN over pharmacologic options.
Provider action — verify benefits and payer rules
Confirm member benefits, eligibility, and any payer-specific requirements before initiating REN to avoid unexpected denials or member liability.
- Use the provider call center for benefit verification.
- Ensure participation agreement terms are followed.
Coverage documentation — refer to benefit booklet/EOC/Subscriber Agreement
Refer to the member's Benefit Booklet, Evidence of Coverage, or Subscriber Agreement for durable medical equipment (DME) benefits and coverage applicability for REN.
- DME benefits/coverage may vary by group and contract; check the appropriate benefit documents.
- Policy coverage statement does not replace the Benefit Booklet or Evidence of Coverage.
Verify member benefits and eligibility — contact provider call center
For member-specific benefits and eligibility, contact the provider call center; benefits are determined by the member's subscriber agreement or employer agreement which supersede this policy.
- Provider call center is the source for eligibility and benefit details.
- Subscriber or employer agreements take precedence over this medical policy.
Benefit variability — check contract-specific DME coverage
Benefits and coverage for REN may vary between groups and contracts; denial can occur if DME benefits do not apply under the member's specific Benefit Booklet, Evidence of Coverage, or Subscriber Agreement.
- Check group- or contract-specific DME benefits before ordering or billing REN.
- Denials may result when the member's contract does not provide DME coverage for the service.
Member financial liability — require written member agreement for non-covered services
If services are determined to be not medically necessary or are non-covered benefits, do not charge the member unless the member has been informed and has agreed in writing in advance to self-pay.
- Obtain written member agreement before providing non-covered services at the member's expense.
- Participation agreements may have additional billing rules.
Background
Migraine is a neurologic disease that includes episodic forms (generally fewer than 15 headache days per month) and chronic forms (≥15 headache days per month). Acute management focuses on rapid symptom relief, while preventive therapy is used for frequent or disabling attacks. Remote electrical neuromodulation (REN), such as the Nerivio device, is a wearable nonpharmacologic option applied to the upper arm that delivers patient-controlled electrical stimulation (device output up to 0–40 mA, sessions up to 45 minutes) to induce conditioned pain modulation; it may be used for acute and, where cleared, preventive treatment per device labeling.
