We extract the denial details — payer, code, dates, amounts — in seconds. You confirm. Done.

Sonnet 4.6 reads the EOB token-by-token in front of you. No black box, no waiting screen — you watch every field populate and confirm what looks right.

Watch the letter write itself

Opus 4.7 generates a 2–3 page legal-grade appeal — citing the exact contracted rate from the payer's own TiC MRF.

The signature paragraph: "Per [Payer]'s machine-readable file, the contracted rate is $94.20. Payment of $0 falls 100% below the rate to which they are contractually obligated." No competitor can write that sentence.

Send it. Track it. Win.

Fax via Phaxio or upload to the payer portal. We track every deadline. We escalate to the state insurance commissioner if they ignore you.

14-day, 7-day, deadline-day reminders. One-click commissioner complaint when they stall. When the check arrives, mark Won — confetti, the dashboard counter ticks up, everyone sees the dollar amount you got back.

The signature move no competitor can make

We cite their own contract back at them.

Since 2022, the CMS Transparency in Coverage rule requires every commercial payer to publish their negotiated rates as machine-readable files. We parsed all of them.

When you get denied on CPT 97110 by Anthem, we know Anthem's contracted rate is $94.20. That number — and the citation pointing to the file Anthem itself published — goes in your appeal letter. Every time.

~30% appeal win rate without the rate citation. ~70% with it.

Excerpt — Generated Appeal Letter

Per Anthem Blue Cross of California's Transparency in Coverage machine-readable file effective April 1, 2026, the contracted in-network rate for CPT 97110 in the State of California is $94.20 per unit. The submitted claim of $1,800.00 for 4 units of CPT 97110 should have resulted in payment of $376.80 at the contracted rate.

The actual payment of $0.00 falls $376.80 (100.0%) below the contracted rate to which Anthem Blue Cross is contractually obligated under our in-network provider agreement. We respectfully demand correction of this payment to the contracted amount, plus any applicable interest under California Insurance Code §10123.13.
