Anthem Blue Cross E/M claim-review policy criticized by CMA
In December 2025 the CMA publicly urged Anthem Blue Cross to rescind a newly announced evaluation-and-management (E/M) claim-review policy, alleging the payer failed to disclose the criteria, methodology or algorithms it would use to adjudicate E/M claims. Anthem’s provider communications (company source) state the payer will review selected E/M claims prior to payment to determine correct coding and reimbursement. The CMA framed its concern as a transparency and patient-care issue and sought policy withdrawal and legislative remedies.
CMA says Anthem failed to disclose the specific criteria, methodology or algorithms it would use to adjudicate E/M claims.

What happened
The California Medical Association publicly urged Anthem Blue Cross to rescind a newly announced policy to review evaluation-and-management (E/M) claims, alleging the insurer did not disclose the criteria, methodology or algorithms it would use. Anthem’s provider bulletin states the insurer will review selected E/M claims prior to payment to determine correct coding and reimbursement. The CMA and related physician groups pressured Anthem and sought legislative remedies to prohibit automatic downcoding and require transparency.
What broke inside the model
- 01 · TriggerA prompt pushes against a deployment boundary.
- 02 · Model stepThe model produces the disallowed output.
- 03 · Control gapNo enforcement blocks it at generation time.
- 04 · FailureThe output crosses the policy line.
- 05 · ConsequenceA limit the business set is breached in public.
The output crosses a policy boundary the deployment had defined.
The reported failure is framed as a governance and transparency failure in automated claim-editing/algorithmic adjudication: physician groups say Anthem's new policy relies on automated edits or undisclosed criteria to downcode or reclassify E/M claims without adequate disclosure or clinical review. That mechanism risks incorrect payment decisions when the rules or algorithmic criteria are opaque or mis-specified, and it prevents clinicians from understanding why claims are adjusted.

Realm compares what the model is about to output or do against the policy that governs the deployment, in real time, and can deny or redact the action before it takes effect, which is the gap an after-the-fact review never closes in time.
