About 12% of claims were denied in 2024, leading to $262 billion in lost revenue to providers. Providers spend about $26 billion annually in recovering denied claims, but only 70% are paid.
That’s what Amperos Health hopes to change. The company is a denial management and revenue recovery solution that helps providers combat denials. It announced on Wednesday that it secured $16 million in Series A funding.
Amperos serves outpatient clinics and physician group practices across all 50 states. Amperos’ AI platform handles providers’ denied claims by dealing with the associated follow-ups, appeals, calls and paperwork. It also provides insights so providers can improve their billing and collections processes and prevent denials in the future.
“The AI that Amperos uses works directly within the provider’s existing billing software, acting like a member of their team rather than a separate platform to manage,” said Michal Miernowski, Amperos CEO. “The result is that providers recover more revenue, at lower cost, without hiring more staff.”
The Series A round was led by Bessemer Venture Partners, with participation from Uncork Capital and Neo. This brings the company’s total funding to $21 million.
“Denials are one of healthcare’s fastest-growing pain points: a growing portion of claims denied, hundreds of billions in lost revenue, and RCM teams that are chronically understaffed. It’s a broken process ripe for AI transformation,” said Sofia Guerra, partner at Bessemer Venture Partners, in a statement. “What sets Amperos apart is that they’re the first truly agentic AI platform we’ve seen to automate this workflow end-to-end, from portal follow-ups and calls to corrected claims and appeals, with no handoffs and no gaps.”
With the funding, Amperos will expand its team to serve more providers across additional specialties and geographies. It currently supports orthopedics, ophthalmology, durable medical equipment, dermatology and behavioral health.
Amperos will also expand its analytics capabilities to help providers understand why claims are denied and continue building out the platform, Miernowski said.
“This means applying the same agentic AI approach to other revenue cycle workflows beyond denial management, which prevents denials and addresses root causes automatically,” he added.
Ultimately, the company aims to become the “AI-native infrastructure layer between providers and payers,” Miernowski stated.
“RCM today is a manual, constantly shifting domain,” he said. “New payer rules, new procedures, and constant staff turnover. It’s nearly impossible for any billing leader to stay ahead without AI. … We don’t want to be just automating the work, but continuously optimizing, to make sure providers can maximize reimbursement. We can make this possible by identifying where denials are occurring and making process changes upstream to prevent them in the first place.”
