Most of it just never gets chased.

Industry reporting puts denial losses at $50,000 to $120,000 a year per practice.

Questions

Is this replacing our office manager?

No. Rex works alongside them. Your team keeps patients, clinical calls, and sign-off on exceptions.

What if it gets something wrong?

Unclear matches wait for review. Every posting links to its source, and corrections are tracked.

Will this work with our practice software?

It stays in place. We confirm how Rex reads, posts and verifies before the pilot.
