How to Get Evkeeza (Evinacumab) Covered by Aetna CVS Health in Michigan: Prior Authorization, Appeals & Cost Guide
Answer Box: Getting Evkeeza Covered in Michigan
Evkeeza (evinacumab) requires prior authorization from Aetna CVS Health for homozygous familial hypercholesterolemia (HoFH). Your fastest path to approval: 1) Confirm HoFH diagnosis with genetic testing or clinical criteria, 2) Document failed trials of maximum-tolerated statins, ezetimibe, and PCSK9 inhibitors, 3) Submit PA request through Aetna's provider portal with complete medical records. If denied, you have 180 days to appeal internally, then 127 days for Michigan's external review through DIFS.

Plan Types & Network Requirements
Your Aetna plan type determines referral and network requirements for Evkeeza treatment:
| Plan Type | Specialist Referral | Network Rules | Prior Auth Required |
|---|---|---|---|
| HMO | Required from PCP | HAP network only | Yes, through HAP |
| PPO | Not required | Michigan in-network only | Yes, through Aetna |
| EPO | Not required | In-network only | Yes, through Aetna |
Note: HAP EPO and PPO members in Michigan must use HAP's authorization process, not Aetna's standard system.
For HMO members, you'll need a referral to see a lipidologist or cardiologist who specializes in HoFH. PPO and EPO members can self-refer but must stay in-network for coverage.
Formulary Status & Tier Placement
Evkeeza is typically placed on Tier 5 (preferred specialty) or Tier 6 (non-preferred specialty) in CVS Caremark formularies. This means higher cost-sharing compared to generic medications.
Alternative HoFH treatments that may have different tier placement include:
- PCSK9 inhibitors (evolocumab, alirocumab)
- Lomitapide (Juxtapid)
- Ezetimibe plus high-intensity statins
- LDL apheresis (covered as a medical benefit)
Your specific formulary tier can be verified through your member portal or by calling CVS Caremark customer service.
Prior Authorization Requirements
All Aetna plans require prior authorization for Evkeeza. The key clinical criteria include:
Medical Necessity Documentation
- Confirmed HoFH diagnosis via genetic testing or clinical criteria (LDL-C >500 mg/dL untreated, tendon xanthomas, family history)
- ICD-10 code E78.01 (familial hypercholesterolemia)
- Prior therapy failures with maximum-tolerated doses of:
- High-intensity statins (atorvastatin 80mg or rosuvastatin 40mg)
- Ezetimibe 10mg daily
- PCSK9 inhibitor (evolocumab or alirocumab)
- Contraindications or intolerances to alternative therapies
- Current lipid panel showing inadequate LDL-C reduction
- Weight-based dosing calculation (15 mg/kg every 4 weeks)
Site of Care Requirements
Evkeeza must be administered at approved infusion centers or specialty clinics. Home infusion may require additional authorization.
Specialty Pharmacy Setup
CVS Specialty Pharmacy typically handles Evkeeza distribution for Aetna members. The setup process includes:
- Prescription routing from your prescriber to CVS Specialty
- Benefits verification and prior authorization submission
- Patient enrollment in CVS specialty services
- Infusion site coordination for administration
- Ongoing refill management and monitoring
Your prescriber's office will coordinate most of these steps, but you may need to complete patient intake forms and provide insurance information.
Cost-Sharing Breakdown
Specialty tier medications typically have the highest cost-sharing in Aetna plans:
- Tier 5 (preferred specialty): $250-$350 copay per 30-day supply
- Tier 6 (non-preferred specialty): Higher copay or 25-40% coinsurance
- Deductible: May apply before copay/coinsurance kicks in
- Out-of-pocket maximum: Annual limit that caps your total costs
Important: These are general ranges. Your exact costs depend on your specific plan design. Check your Summary of Benefits and Coverage (SBC) for precise amounts.

From Our Advocates
"We've seen the strongest approvals when providers submit comprehensive trial-and-failure documentation upfront rather than waiting for the denial. Include specific medication names, doses, duration of therapy, and quantified LDL-C responses. One case we reviewed had a reversal on appeal simply because the physician added the patient's weight-based dosing calculation and cited the FDA prescribing information directly."
Getting specialized treatments like Evkeeza approved requires persistence and thorough documentation, but Michigan patients have strong appeal rights when denials occur. Counterforce Health helps patients and providers navigate these complex approval processes by turning insurance denials into targeted, evidence-backed appeals. Our platform analyzes denial letters and plan policies to identify the specific reasons for denial, then drafts point-by-point rebuttals using the right clinical evidence and payer-specific requirements.
For patients facing Evkeeza denials, the key is understanding your plan's specific requirements and building a comprehensive case that addresses each coverage criterion. With proper documentation and strategic appeals, many initially denied specialty medications can ultimately be approved.
