Trek Health ingests and normalizes Transparency in Coverage data and payer policy updates to give provider organizations a clear view of how commercial reimbursement behaves across markets, payers, and services. Our platform transforms raw payer disclosures into structured intelligence that supports contract evaluation, payer negotiations, and service line strategy. By combining market benchmarks with ongoing policy visibility, Trek helps teams identify variability, risk, and opportunity in commercial reimbursement. The result is faster insight, stronger negotiating positions, and more informed financial decisions.

Provider Actions & Billing Rules

Prior Authorization

Prior authorization required with documentation

Providers must obtain prior authorization and submit documentation including: attestation of migraine diagnosis; documentation that the member experiences ≥ 4 migraine days per month for at least 3 months; trial/failure documentation of required preventive therapies per age group (adults: failure of at least 2 oral preventive therapies from different classes each for 8 weeks; ages 12–17: failure of an 8-week trial of topiramate unless contraindicated); current pediatric weight for ages 6–17 (≥ 45 kg); and confirmation that requested dosing does not exceed policy limits.

Affected HCPCS code: J3031

Documentation Required

Documentation for concurrent Botox use

For requests to use Ajovy concurrently with Botox, submit supportive evidence of concurrent use including at least two high-quality, published studies or evidence-based clinical practice guidelines that adequately represent the member and regimen and report clinically meaningful outcomes. Provide documentation that the member experienced and maintained a positive response to Botox monotherapy evidenced by ≥ 30% reduction in migraine days per month from baseline after at least 2 quarterly injections (6 months). Also document that despite Botox monotherapy the member continues to have ≥ 4 migraine days per month and/or severe, disabling migraine headaches.

Clinical Evidence & References

Evidence sources referenced in the brief include the Ajovy Prescribing Information, Teva Pharmaceuticals, August 2025 and guideline citations (AAN, AHS, ACP and other guideline references cited in the policy).

The policy requires supportive evidence for certain uses (for example, concurrent use with Botox) from at least two high-quality, published studies or evidence-based clinical practice guidelines.

The policy defines High-quality evidence as randomized, prospective controlled trials or robust non-randomized prospective trials and explicitly states that case reports and chart reviews are not considered high-quality evidence.

Background

Background: Fremanezumab-vfrm (Ajovy) is a CGRP receptor antagonist indicated for preventive treatment of migraine in adults and for episodic migraine in pediatric patients age 6–17 years who weigh ≥ 45 kg, consistent with FDA-approved indications.

Policy alignment and requirements: The policy aligns coverage to FDA indications and requires documentation of migraine frequency—provider attestation of ≥ 4 migraine days per month for at least 3 months—and, for adults, documentation of failure of at least 2 different oral preventive therapies (each for 8 weeks unless contraindicated). For ages 12–17 additional redirection to topiramate is specified per recent updates. The policy also requires documentation of current weight for pediatric patients and that dosing does not exceed the policy limits (e.g., 225 mg once monthly or 675 mg every 3 months for adults).

Scope clarification: The policy applies to commercial lines and explicitly does not apply to California Exchange Plans; requests for those plans should be reviewed using HIM.PA.SP66.

Definitions

Migraine day (definition)Any calendar day with headache lasting ≥2 consecutive hours meeting ICHD-3 criteria for migraine or probable migraine, or any duration headache treated with migraine-specific medications (triptans or ergots).

High-quality evidence (definition)Randomized, prospective controlled trials or robust non-randomized prospective trials; case reports and chart reviews are not considered high-quality.
