Aetna's Specific Approach to Spinal Fusion
Applicable Policy
Aetna CPB 0743 (Spinal Surgery: Spinal Fusion)
How Aetna Typically Denies This
Aetna CPB 0743 has specific BMI cutoffs (often >40 requires optimization) and requires a documented smoking cessation period. They also require psychological evaluation for patients with chronic pain >6 months.
Your Strategy for This Payer
Aetna is very criteria-driven for spinal fusion. If BMI or smoking is the barrier, document optimization efforts. The psychological evaluation requirement is firm -- if it hasn't been done, the call won't succeed.
Key Phrase to Use on the Call
"Per CPB 0743, the patient has completed all prerequisite evaluations including [psychological clearance/smoking cessation/BMI optimization] and meets surgical criteria with documented instability and failed conservative care."
Building Your Medical Necessity Argument
Document instability on flexion-extension films
Show failure of 6+ months conservative care including PT, injections, medications
Note progressive neurological deficits
Address smoking cessation and BMI if applicable
