LunaBill

LunaBill is an AI revenue cycle platform that works accounts receivable for hospitals the way a billing representative does, on every claim, every day. Its agents verify eligibility before a claim stalls, check claim status in payer portals, phone insurance companies and sit through IVR menus and hold queues, read denials and draft and file appeals, resubmit claims with corrected data, and post payments back into the EHR. It is built for hospital and health system billing teams, revenue cycle management firms and business process outsourcers that handle billing for providers. Luna works inside the systems those teams already use, with Epic, Cerner, GoRev, Waystar and Availity named, and the vendor states that a pilot can be running within 48 hours. Every action is logged, giving RCM firms an audit trail they can hand to their own clients. The platform is HIPAA compliant and SOC 2 Type II certified. Pricing is performance based rather than licensed. The vendor's terms are $0 upfront, no license fees and no implementation fees, with the fee taken as a share of net collections recovered and the rate set per customer. If nothing is recovered, nothing is owed. LunaBill is a Y Combinator company and publishes a case study with a hospital operator describing recovered collections, the kind of evidence a billing director will want to see reproduced in their own numbers during a pilot.
