How Anthem BCBS Typically Denies This
Anthem frequently denies single-level fusions for degenerative disc disease without documented instability. They require clear documentation that the pain generator is at the level being fused.
Your Strategy for This Payer
Anthem wants to see concordance between imaging, symptoms, and the proposed surgical level. Provocative discography or diagnostic injections that confirm the pain generator at the fusion level significantly strengthen your case.
Key Phrase to Use on the Call
"Diagnostic [injection/discography] confirmed the pain generator at [level], which is concordant with the MRI findings and clinical presentation, meeting SURG.00018 criteria for surgical intervention."
