Common Denial Reasons & How to Fix Them

Denial Reason How to Overturn Required Documents
Missing CFTR genotype Submit genetic testing results showing sensitive mutations Lab report with F508del or other qualifying mutations
Lack of baseline labs Provide liver function tests and other required monitoring Recent ALT, AST, bilirubin levels
Drug-drug interactions Document medication review and management plan Current medication list with interaction assessment
Quantity limits exceeded Justify dosing based on FDA labeling and patient weight Prescriber letter explaining dosing rationale
Not medically necessary Demonstrate CF progression despite standard therapy Pulmonary function decline, hospitalizations, prior treatment failures
From our advocates: We've seen cases where patients were initially denied for "missing genetic testing" even when CFTR results were in their chart. The key was having the CF center resubmit the exact genetic panel report with highlighted mutations that match Trikafta's FDA labeling. This simple documentation fix led to approval within days.

Frequently Asked Questions

How long does Blue Shield's PA process take in California?
Standard prior authorization decisions are made within 14 business days. Expedited reviews for urgent situations are completed within 72 hours.

What if Trikafta isn't on my formulary?
You can request a formulary exception by having your doctor submit documentation showing why covered alternatives are inappropriate. Submit via fax at (844) 958-0934 or through the member portal.

Can I request an expedited appeal?
Yes, if your condition is urgent (hospitalization risk, significant health deterioration), you can request expedited review at both internal appeal and IMR levels.

Does step therapy apply if I failed medications in another state?
Medical records from any state showing prior treatment failures should satisfy step therapy requirements. Ensure your CF center includes this documentation in the PA submission.

What happens if I'm approved but then denied at renewal?
Annual renewals require updated documentation including recent pulmonary function tests and stability notes. Start the renewal process 30-60 days before your current authorization expires.

How much will Trikafta cost with Blue Shield coverage?
As a specialty tier medication, you'll typically pay 33% coinsurance, but many plans cap specialty drug costs at around $250 per 30-day supply. Check your specific plan documents for exact amounts.

Can I appeal if Blue Shield requires a different CFTR modulator first?
Yes, if your doctor can demonstrate that alternative CFTR modulators would be less effective or cause adverse effects based on your specific genetic mutations, you can override step therapy requirements.

What if Blue Shield doesn't respond within their stated timeframes?
California law may require auto-approval if insurers miss deadlines. Contact DMHC immediately if Blue Shield fails to respond within required timeframes.
