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.

Regulatory Posture applies to this provider. Its tags matched the Health regime, so Regulatory Posture carries 15 points of the composite. If this regime is wrong for your business, say so on your provider repo — the applicability map is public and we will correct it.
The six quality facets above are damped to 85 points between them, because the conditional facet above carries the other 15. That is why each facet's contribution is shown against a damped maximum: raising a quality facet moves the composite by 85% of its nominal weight, not 100%. The full arithmetic is at apis.io/rating/.
Improve this rating by publishing the missing artifacts — every area above can be raised, and the full rubric is at apis.io/rating/. This rating is computed from github.com/api-evangelist/lunabill: open an issue to ask a question, or submit a pull request to add artifacts. Want it done for you? Prioritized profiling — $2,500 →
