AI and Medicare: Impacts of the WISeR Model on Service Delivery

In early 2023, Medicare launched the Wasteful and Inappropriate Service Reduction (WISeR) Model, a pilot initiative spanning six states: Washington, Arizona, New Jersey, Ohio, Oklahoma, and Texas. This program enables private companies to employ artificial intelligence (AI) for reviewing and potentially denying Medicare claims. Consequently, this AI-driven prior authorization mechanism has reportedly increased delays and denials of medical procedures, impacting patients and healthcare providers significantly.

While the WISeR program aims to streamline claims review through AI integration, those involved are encountering substantial challenges. Frequent care denials due to AI assessments are frustrating both patients and doctors. The shift towards requiring prior authorization within traditional Medicare—a routine practice in Medicare Advantage and employer-sponsored health plans—alters traditional claims handling, introducing cumbersome preapproval processes for procedures.

Data reveals that many denied prior authorization requests in Medicare Advantage plans are overturned on appeal, yet the demanding appeal process discourages challenges to initial denials. These delays can worsen health conditions and potentially escalate overall healthcare costs. While the Department of Health and Human Services (HHS) endorses the program as a Medicare fraud mitigation strategy, the lack of clarity around its basics and operations leaves healthcare providers seeking regulatory guidance.

Legislators, including Representative Suzan DelBene, have voiced concerns over the WISeR Model, citing it as an incentive to limit care availability. This reflects a wider trend of integrating private companies in Medicare processes. Current legislative efforts aim to halt the initiative, stressing the importance of safeguarding senior patients’ timely access to medical care. As the program's impact continues to unfold, industry stakeholders and observers remain vigilant regarding its implications for Medicare's service delivery and the insurance sector at large.
