The problem, in one number

Most practices leave the easiest revenue on the table.

Denied claims are the most appealable, most policy-grounded revenue in a specialty practice — and the least pursued. AZREX is built around closing that gap.

Honest answers

Questions worth
asking out loud.

Five things admins and physicians ask in the first call. The answers don't change after you sign.

Ask us something else
No — and that's intentional. Every appeal still needs a physician's review and signature before it leaves your practice. AZREX writes the draft and pulls in the supporting policy citations; a human in your practice always sends it.
We start with the major national plans (UnitedHealthcare, Aetna, Cigna, Anthem) plus Medicare Advantage variants. Regional and state plans are added based on what our partner practices need. If your top payer isn't on the list, tell us — adding a new payer's policy library usually takes one to two weeks.
Patient data is automatically redacted before our drafting tool sees the document. Each practice's records are kept completely separate from every other practice's, and every action is logged — you can export the full activity history any time. We sign BAAs.
Pre-launch pricing is still being set with our partner practices. We expect a flat monthly fee per practice plus a small per-appeal cost, with no contingency or percentage-of-recovery model. We'll publish exact pricing once the pilot phase closes — happy to share what we're thinking on a call.

No. AZREX works from the documents your practice already has — denial letters, EOBs, chart notes — uploaded directly or forwarded by email. EHR integrations (Epic, Athena, eClinicalWorks) are on the roadmap for practices that want them, but they're not required to start.
