Common Denial Reasons & How to Fix Them

Denial Reason How to Overturn Documents to Include
"Missing prior treatment documentation" Provide detailed treatment history with dates, doses, outcomes Pharmacy records, infusion logs, provider notes showing progression/intolerance
"Step therapy not completed" Document contraindications or failures of required first-line therapies Medical records showing allergies, adverse events, or disease progression on required drugs
"Not meeting medical necessity criteria" Submit comprehensive clinical narrative addressing each policy requirement Updated staging, functional status, symptom burden, treatment goals
"Site of care restrictions" Justify infusion center/hospital setting if required Documentation of patient needs, safety considerations, or provider capabilities
"Experimental/investigational" Emphasize FDA approval for mycosis fungoides/Sézary syndrome FDA labeling, NCCN guidelines, peer-reviewed literature
From our advocates: We've seen many BCBS denials overturned when patients include a detailed timeline showing how their disease progressed despite multiple prior therapies. The key is connecting each treatment failure directly to the current need for Poteligeo, making it clear this isn't a first-line request but a necessary next step after documented failures.

Q: What if Poteligeo is not on my plan's formulary? A: Poteligeo is typically covered under medical benefits (not pharmacy formulary) since it requires IV infusion. Verify with your plan whether it's covered as a medical benefit for your specific diagnosis.

Q: Can I request an expedited appeal if denied? A: Yes, if your physician certifies that delay could seriously jeopardize your health. Washington law requires expedited processing (72 hours) for urgent appeals.

Q: Does step therapy apply if I've tried treatments outside Washington? A: Prior treatments from other states should count toward step therapy requirements. Include complete documentation of all prior therapies regardless of where they were administered.
