Eliott Dear: Decoding the Anthem EOB — How a Carrier Prices an Out-of-Network Claim

Every Anthem out-of-network commercial claim comes back on an EOB with a single allowed amount per CPT code. The figure looks definitive. The pricing behind it is not.

Eliott Dear has spent years inside Anthem out-of-network disputes — Empire BCBS, Anthem HealthChoice, Anthem HP LLC, the BlueCard PPO layer. The mechanics are decipherable and the gaps are documentable.

The Allowed Amount on Paper

The EOB gives the billed charge, the allowed amount and the adjustment codes. It does not give the method. Some Anthem claims are priced through MultiPlan, some internally, and the EOB rarely says which.

That is the headline. The audit-trail problem is the body.

The Adjustment-Code Field

The adjustment-code field is where the EOB explains the cut, in shorthand. A code like CO-45 sitting beside the gap between the billed charge and the allowed amount marks the line where the carrier priced the claim down.

That is a challenge point. Comparing the Anthem allowed amount to the FAIR Health 80th percentile for the same code and geo-zip is standard diligence on every Anthem claim.

The MultiPlan Layer

MultiPlan operates a separate OON pricing layer that Anthem and other carriers route some claims through. The MultiPlan repricing is sometimes used as the initial payment amount on the claim. The interaction is opaque on the EOB. MultiPlan-related lawsuits filed by hospital systems and physician groups have put that pricing flow under scrutiny.

Whether a specific Anthem claim flowed through MultiPlan is rarely indicated on the EOB explicitly. Reading the adjustment-code field alongside a specific allowed-vs-charge gap pattern is one signal.

The Challenge Path in New York State IDR

A New York State IDR submission that pulls the FAIR Health 80th-percentile UCR for the relevant geo-zip and code, compares it to the Anthem allowed amount, and documents the gap puts the full benchmark evidence in front of the arbitrator.

That is the work. The allowed amount is not unchallengeable. Eliott Dear and Claims Assassins document the gap on Anthem ER and surgery filings.
