Elevance Health cuts prior authorization denials by 61% with Health OS
Elevance Health's Health OS platform has significantly improved clinical review processes, reducing prior authorization denials by 61% and cutting administrative time by 15 minutes per case. The system processed over 250,000 requests in early 2026, with 42% of decisions completed in under a minute. By integrating with Epic’s Payer Platform, Health OS streamlines workflows for care providers and enhances the care experience for members.

Elevance Health today announced advancements in its Health OS platform, a secure data system designed to streamline clinical review and create a simpler, faster, and more connected experience for care providers and members. The platform connects health information across electronic health records (EHRs), labs, and health information exchanges to support more informed and timely clinical decisions while reducing administrative burden. By integrating with healthcare data systems, including Epic’s Payer Platform, Health OS helps reduce manual steps and deliver clearer clinical insights.
Health OS represents a shift from fragmented, manual processes to a connected, intelligent ecosystem, said Ashok Chennuru, Chief Data and Digital Transformation Officer at Elevance Health. The system enables faster decisions and reduces administrative work by applying advanced analytics and embedding data-driven insights directly into workflows between care providers, payers, and other partners. Elevance Health was the first to collaborate with Epic in leveraging the Epic Payer Platform for inpatient concurrent reviews, which historically relied on manual documentation submissions leading to delays.
Early results from health systems using Health OS-enabled workflows demonstrate meaningful improvements in efficiency and accuracy. A key outcome includes a 61% reduction in prior authorization denials due to insufficient clinical information. Additionally, nearly 60% fewer cases were designated pending because of the need for additional information. The platform also drove up to a 51% reduction in follow-up reviews, including appeals and peer-to-peer discussions, by ensuring more complete information upfront. Care providers reported saving approximately 15 minutes of administrative time per case, along with a more transparent and efficient process.
Impact on Prior Authorization
Health OS is transforming prior authorization for medical services by integrating it into provider workflows and allowing secure information sharing between providers and the health plan. This approach significantly reduces reliance on phone, fax, and paper submissions while improving speed and consistency. More than 30 health systems are actively participating in Elevance Health’s program for electronic prior authorization for medical services.
Results from this participation highlight the platform's impact. In 2026 through the end of April, more than 250,000 prior authorization requests for medical services were processed. Of these, more than 42% of decisions were completed in one minute or less. For providers, this translates to reduced administrative burden and a more intuitive experience that aligns with existing workflows. For members, it means faster access to approved treatments and a more predictable care journey.
"Much of the waste and complexity in healthcare could be reduced by simply making the right information available to the right stakeholders," said Alan Hutchison, Vice President at Epic. He noted that Epic’s Payer Platform has enabled meaningful reductions in administrative burden with measurable reductions in denials, peer-to-peer reviews, and appeals, resulting in less work for providers and faster access to care for patients. Elevance Health remains focused on expanding its capabilities to advance a future where utilization management is faster, simpler, and more aligned with patient care.
How will Elevance Health plan to scale the Health OS platform to include smaller health systems that may not use Epic’s Payer Platform?
What are the long-term cost implications for Elevance Health as the platform reduces administrative overhead and potentially lowers the volume of appeals and peer-to-peer reviews?
Could the success of Health OS prompt regulatory bodies to mandate similar interoperability standards for prior authorizations across the entire healthcare industry?
