Health Samurai has launched RCMbox, a modular, FHIR-native billing infrastructure platform built for engineering teams developing healthcare products — telehealth apps, EHR platforms, RCM platforms and specialty care tools that need production-ready billing without building it from scratch.
The problem
Billing is one of the most expensive parts of a healthcare product to build. Claims, ERAs, payer routing, X12 — each is a separate engineering project. Off-the-shelf tools assume traditional clinical workflows and don't fit your business processes. Custom builds work, but they consume roadmap capacity teams can't afford.
What RCMbox is
RCMbox deploys inside a team's own infrastructure as a workflow engine which executes TypeScript-based workflows. It covers the full billing cycle — claim generation, scrubbing, EDI output, ERA matching, remittance posting — with full code visibility at every step.
It is FHIR-native throughout. No black boxes. No vendor lock-in. The code belongs to the team that deploys it.
"Every new payer, every rule change — product teams are solving these from scratch and it's eating their roadmaps," said Denis Zavyalov, RCMbox Product Owner, Health Samurai. "RCMbox gives them billing infrastructure they can ship in weeks and actually own."
What it includes
- Workflow execution engine
- UI for workflow introspection
- Pre-built workflows for the full pre- and post-bill cycle
- X12 837/835 generation and parsing out of the box
- Native integrations with FHIR APIs (for instance Athena, Cerner etc.)
- Configurable validation rules with full audit trail
- AI assistant for generating billing logic in TypeScript
- Aidbox FHIR Server as the underlying data engine
Getting started
RCMbox is available now. Health Samurai engineers work with each team to define the right implementation path — whether that means deploying independently, building with guidance, or having Health Samurai implement it end to end.
