How to Get Evkeeza (Evinacumab-dgnb) Covered by Humana in California: Complete Prior Authorization and Appeals Guide

Answer Box: Fastest Path to Evkeeza Coverage

Humana requires prior authorization for Evkeeza (evinacumab-dgnb) as a Tier 5 specialty medication. To get approved in California: 1) Gather HoFH diagnosis documentation (genetic testing showing pathogenic variants in LDLR, APOB, PCSK9, or LDLRAP1 genes, plus LDL-C >400 mg/dL untreated), 2) Document failure/intolerance to maximally tolerated background therapies (statins, ezetimibe, PCSK9 inhibitors), and 3) Submit PA via Humana provider portal with specialist prescription. If denied, you have 65 days to appeal and can request California's Independent Medical Review (IMR) through DMHC for binding external review.

Understanding Your Denial Letter

When Humana denies your Evkeeza prior authorization, the denial letter will include specific reason codes. Here's how to decode the most common ones:

Medical Necessity Denial: Humana determined the medication isn't medically necessary based on their coverage criteria. This often means missing documentation of HoFH diagnosis or inadequate prior therapy trials.

Non-Formulary Status: While Evkeeza is on Humana's formulary as Tier 5, specific plan variations may require formulary exceptions.

Step Therapy Requirements: You must try and fail other cholesterol medications before Evkeeza is covered, unless contraindicated.

Quantity Limits: Humana limits Evkeeza to one 15 mg/kg dose every 4 weeks based on FDA dosing guidelines.

Common Denial Reasons & How to Fix Them

Denial Reason How to Overturn Required Documents
Incomplete HoFH diagnosis Submit genetic testing results or detailed clinical criteria documentation Pathogenic variant report, untreated LDL-C >400 mg/dL, family history
Insufficient prior therapy Provide complete treatment history with dates, doses, and outcomes Pharmacy records, provider notes, adverse event documentation
Missing current labs Submit recent LDL-C levels within 90 days Lab reports showing persistent elevation despite therapy
Non-specialist prescriber Have lipidologist, cardiologist, or endocrinologist submit PA Provider credentials, specialist consultation notes
Incomplete submission Ensure all required fields and supporting documents are included Complete PA form, medical records, FDA labeling references
From our advocates: We've seen many Evkeeza denials overturned when families worked closely with their specialist to document the complete treatment journey. One key tip: organize prior therapy records chronologically with clear start/stop dates and specific reasons for discontinuation. This creates a compelling narrative that reviewers can easily follow and helps establish medical necessity more effectively.

What if Evkeeza is non-formulary on my specific Humana plan? Even if not on your plan's formulary, you can request a formulary exception based on medical necessity. Submit the same documentation required for PA along with a formulary exception request explaining why covered alternatives are inappropriate.

Can I request an expedited appeal if I'm already on Evkeeza? Yes, if discontinuing treatment would jeopardize your health or life, you can request an expedited appeal. Your prescriber must document the urgency and potential medical consequences of treatment interruption.

Does step therapy apply if I failed therapies outside California? Prior therapy failures from any state count toward meeting Humana's step therapy requirements. Ensure you have documentation of the treatments tried, including dates, doses, and reasons for discontinuation.

What happens if California IMR upholds Humana's denial? IMR decisions are binding on health plans. If the IMR upholds the denial, you may explore alternative treatments, seek a second opinion, or consider changing insurance plans during the next open enrollment period.

How do I track my appeal status? Use Humana's online member portal or call the customer service number on your insurance card. Keep detailed records of all communications, including dates, representative names, and reference numbers.

Can my doctor bill for the peer-to-peer review call? Peer-to-peer reviews are not separately billable and are considered part of the appeals process. However, the time spent preparing for and conducting the call may be factored into overall case management.

What if I need Evkeeza while my appeal is pending? For urgent situations, request an expedited appeal and ask your prescriber to document the medical urgency.
