How Anthem BCBS Typically Denies This

Anthem routes all MSK imaging through AIM Specialty Health. AIM has its own clinical criteria separate from Anthem's medical policies. Denials often cite lack of documented physical exam findings.

Your Strategy for This Payer

Your P2P will be with an AIM reviewer, not an Anthem medical director. Focus on documented physical exam findings: straight leg raise, motor strength grading, sensory deficits. AIM wants objective findings, not just subjective complaints.

Key Phrase to Use on the Call

"The documented neurological exam findings -- including positive SLR at [X] degrees and [specific motor deficit] -- meet AIM's clinical criteria for advanced imaging."

Building Your Medical Necessity Argument

Document failure of 6+ weeks conservative management

Note neurological deficits (radiculopathy, motor weakness, bowel/bladder changes)

Reference progressive symptoms despite treatment

Cite red flag symptoms if present (trauma, cancer history, infection risk)
