How to Get Palynziq (pegvaliase-pqpz) Covered by Blue Cross Blue Shield in California: Complete Prior Authorization and Appeals Guide
Answer Box: Getting Palynziq Covered in California
Blue Cross Blue Shield (BCBS Association) requires prior authorization for Palynziq (pegvaliase-pqpz) in California, with coverage limited to PKU patients titrating to achieve blood phenylalanine ≤600 µmol/L. The fastest path: submit PA via provider portal with PKU diagnosis, current Phe levels, and prior therapy documentation. If denied, file internal appeal within 180 days, then escalate to California's Independent Medical Review (IMR) within 6 months for binding external review with 55-69% overturn rates for specialty drugs.
First step today: Contact your prescriber to gather PKU diagnosis confirmation, recent Phe lab results, and documentation of prior treatment failures to prepare your prior authorization request.

Why California State Rules Matter for Palynziq Coverage
California's robust insurance regulations provide stronger patient protections than many states, especially for specialty drugs like Palynziq. The state operates under dual regulation: the Department of Managed Health Care (DMHC) oversees most HMOs and managed care plans, while the California Department of Insurance (CDI) regulates other health policies.
Key California advantages for Palynziq patients:
- No-fee external review: Independent Medical Review (IMR) is free to patients
- High overturn rates: 55-69% success rate for medical necessity denials in 2023
- Expedited timelines: Urgent cases resolved in 72 hours to 7 days
- Step therapy protections: Clear exception criteria under AB 374 and AB 347
For PKU patients, this means stronger leverage when Blue Cross Blue Shield initially denies Palynziq as "experimental" or "not medically necessary."
Blue Cross Blue Shield Prior Authorization Requirements
Blue Shield of California requires prior authorization for Palynziq under its commercial medication policy, effective November 2, 2023. The coverage criteria are specific and must be met for approval.

California Appeal Timelines and Standards
California's Knox-Keene Act establishes strict timelines that protect patients from prolonged delays:
Standard vs. Expedited Reviews
| Review Type | Prior Auth | Internal Appeal | IMR | When to Use Expedited |
|---|---|---|---|---|
| Standard | 72 hours | 30 days | 45 days | Routine coverage requests |
| Expedited | 24 hours | 72 hours | 3-7 days | Imminent serious threat to health |
Expedited criteria for Palynziq: Uncontrolled phenylalanine levels >600 µmol/L with risk of neurological complications, especially if sapropterin has failed or is contraindicated.
Tip: Always request expedited review if your Phe levels are dangerously elevated. Document the urgency in your request.
Step Therapy Protections and Medical Exceptions
California's AB 374 (2015) and AB 347 (2021) provide clear pathways to override step therapy requirements that might delay Palynziq access.
Medical Exception Criteria
Your prescriber can request a step therapy exception if:
- The required first-line therapy is contraindicated
- You've previously tried and failed the required therapy
- The required therapy caused adverse effects
- You're stable on current therapy and switching poses risks
Documentation That Helps
When requesting exceptions, include specific language:
- "Patient previously trialed sapropterin 20mg daily for 6 months with inadequate Phe reduction (levels remained >800 µmol/L)"
- "Low-phenylalanine diet alone insufficient to maintain Phe <600 µmol/L despite nutritionist supervision"
- "Contraindication to standard therapy due to [specific medical reason]"
Independent Medical Review (IMR) Process
California's IMR system offers the strongest consumer protection for Palynziq denials. Independent physician experts review your case and make binding decisions.
IMR Success Rates (2023 DMHC Data)
- Medical necessity denials: 55.3% overturned overall
- Anthem (similar to BCBS): 68.6% overturned for medical necessity
- Experimental/investigational: 49.1% overturned
How to File IMR
- Eligibility: Must exhaust internal appeals first (or wait 30 days for plan non-response)
- Deadline: 6 months from final internal denial
- Cost: Free to patients
- Filing: Online at HealthHelp.ca.gov or call 888-466-2219
What to Include in Your IMR
- Complete denial correspondence
- All medical records related to PKU diagnosis and treatment
- Prescriber letter explaining medical necessity
- Published studies supporting Palynziq efficacy
- Evidence of prior therapy failures
Common Denial Reasons and How to Fix Them
| Denial Reason | How to Overturn | Required Documentation |
|---|---|---|
| "Not meeting age criteria" | Confirm patient is 18+ | Birth certificate, ID |
| "Phe level insufficient" | Provide recent labs | Lab results showing Phe >600 µmol/L |
| "Step therapy not completed" | Document prior failures | Treatment history, response data |
| "Not medically necessary" | Clinical rationale | Specialist letter, guidelines |
| "Experimental/investigational" | FDA approval evidence | FDA label, published studies |
From Our Advocates
We've seen Palynziq denials overturned when families gathered comprehensive documentation upfront. One effective approach: ask your PKU specialist to create a timeline showing how dietary management and sapropterin trials didn't achieve target Phe levels, then connect this directly to neurological risk. This composite strategy has helped families avoid prolonged appeals.
