Codex Medical Billing

Some health plans now use software to cut your payment on a claim no human ever read.

The AMA has documented it. Certain payer policies let a tool downcode a visit with no review of the medical record.

You bill a 99215. You get paid a 99214, sometimes a 99213.

No denial. No notice. Just a smaller number on the remittance.

A handful of major payers are doing this, and the policies are public.

Cigna launched its E/M Coding Accuracy policy (R49) on October 1, 2025, aimed at level 4 and 5 office visits. 99204, 99205, 99214, 99215.

BCBS Illinois announced in March that it will start reducing E/M payments that don't match the level billed, effective July 1, 2026.

The targets are the high-complexity visits. The ones that pay the most.

One downgrade knocks a level 5 to a 4 or a 3. Run that across a full schedule and the lost revenue stacks up fast.

Providers are fighting this, and they're winning.

Maryland fined Cigna $80,000 in March and ordered it to stop the automatic downcoding and reprocess affected claims.

Anthem Blue Cross of California paused its own downcoding policy under pressure.

The AMA's stance is direct. Downcoding without a medical-record review and proper notice is inappropriate, and practices should read every remittance.

These reductions are appealable.

Strong documentation of your medical decision-making or your time gets the payment restored.

This is exactly the kind of thing we handle at Codex every day. We catch the downgrades, document the complexity, and appeal what the software got wrong.

So here's the question for every practice owner reading this.

Are you reading your remittances line by line, or trusting a system built to pay you less?
