Lunabill

LunaBill is an AI revenue cycle management (RCM) platform for hospitals, health systems, and RCM/BPO firms, built by LunaHealth Technologies, Inc. and backed by Y Combinator. A coordinated team of AI agents works the entire accounts receivable queue end to end — placing real calls to payers and waiting on hold, navigating IVR phone trees, checking payer portals (Availity, Waystar), working denials, filing appeals, and resubmitting claims — while running inside the EHR and clearinghouses a provider already uses (Epic, Cerner, GoRev, Waystar, Availity) and leaving a full audit trail on every claim. Pricing is performance based (1.5% of net collections recovered, nothing upfront). LunaBill is HIPAA compliant and SOC 2 Type I (Type II in progress). It does not currently publish a public developer API; integration is delivered through EHR and clearinghouse connectors rather than a documented API surface.

Lunabill is profiled on the APIs.io network. Tagged areas include Company, Healthcare, Revenue Cycle Management, Medical Billing, and Insurance Claims.

Lunabill’s developer surface includes engineering blog and 7 more developer resources.
