When you need RCMbox
Billing lives across too many tools — and none of them fits your process well.
Claims, ERAs, payer routing — each one is a separate build that pulls your team off what actually matters.
Telehealth, async care, subscriptions — generic billing assumes a workflow that isn’t yours.
New 837 quirks, new ERA format, new denial codes — figured out from scratch every time.
Every rule change goes through someone else’s release cycle. You’ve lost control of your own product.
Pre-built claims, ERAs, X12, and more — configure around your workflows without building from scratch.
Self-hosted, transparent TypeScript throughout. No black boxes, no vendor lock-in.
Telehealth, async, subscription — configure billing around your care model, not the other way around.
FHIR-native internals make integration with EHRs and health APIs straightforward out of the box.
Where RCMbox fits in your stack
Deploys inside your infrastructure — between your product and the clearinghouse. You own the code, the data, and the logic.
