LunaBill

LunaBill is an AI revenue cycle management (RCM) platform that automates accounts receivable work for hospitals, health systems, and RCM/BPO firms. A coordinated set of AI agents handles each claim from submission to payment: verifying eligibility and coverage, pulling status, denial codes and payment details from payer portals, placing claim status calls to payers (navigating IVR phone trees and waiting on hold for a live representative), reading and responding to denials, drafting and filing appeals with supporting records attached, correcting and resubmitting claims (for example payer ID or coordination-of-benefits errors), and posting payments, reference numbers and notes back into the customer's EHR.

The stated workflow is that when a claim sits unpaid past the payer's clock, the system first checks the payer portal, then calls the payer to obtain reprocessing or escalation with a reference number, and files an appeal if the claim was denied, with every action written back to the EHR. The company positions billing staff as reviewing outcomes and retaining judgment calls while the agents perform the repetitive volume work. LunaBill states it integrates with Epic, Cerner, GoRev, Waystar and Availity, is HIPAA compliant with enterprise-grade security and SOC 2 Type II, executes a BAA in under a day, and maintains a public trust center. Cofounder and CEO Suhail Parry frames the revenue cycle as an infrastructure problem rather than a staffing problem.

Business model

LunaBill sells software-driven claim follow-up to health systems and RCM firms on a performance basis rather than a license: customers pay only from recovered revenue, with no upfront, license or implementation fees. Deployment is designed to work inside the customer's existing EHR and clearinghouse stack, with pilots starting quickly.

Performance-based pricing: 1.5% of net collections recovered, billed only after the money is received. No upfront charges, license fees or implementation fees; if nothing is recovered, no fee is owed.

Traction

The site cites Nutex Health, a 24-campus U.S. health system with a 60+ person revenue cycle team, as a reference customer where LunaBill worked more than $32M of AR in 30 days with no added headcount; days in AR on commercial claims aged 60+ days fell from 45 to 7 within three months of go-live, per-claim follow-up time fell from 22 to 4 minutes, and fully loaded cost per claim moved from a $22.28 internal benchmark to $2.00. Portfolio-wide, the company reports more than 90,000 payer interactions per month (trailing 30 days). Additional customers listed are GeBBS, PharmBills and UnisLink.
