Aetna's Specific Approach to Biologic Therapy (Autoimmune)
Applicable Policy
Aetna CPB 0314 (Tumor Necrosis Factor Antagonists) or applicable CPB by drug class
How Aetna Typically Denies This
Aetna has very detailed CPBs for each biologic class with specific disease activity score requirements (DAS28 >3.2 for moderate RA, CDAI >10). They require documentation of these scores, not just a statement of active disease.
Your Strategy for This Payer
Calculate and document the exact disease activity score before the call. Aetna CPBs specify numeric thresholds -- meeting the number makes the approval straightforward. Missing the score is the most common denial reason.
Key Phrase to Use on the Call
"Per CPB 0314, the patient's [DAS28/CDAI/PASI] score of [X] exceeds the threshold for moderate-to-severe disease, confirming active disease despite [conventional DMARD] therapy."
Building Your Medical Necessity Argument
Document failure, intolerance, or contraindication to step therapy agents
Note disease activity scores (DAS28, CDAI, PASI)
If biosimilar switch requested, document clinical reason for brand
Reference comorbidities that limit alternative treatments
