Senators Investigate Medicare Advantage Insurers' Prior Authorization Practices

Recent reports from the Department of Health and Human Services Inspector General (HHS OIG) have highlighted concerns surrounding Medicare Advantage insurers' use of prior authorization processes that could adversely impact senior care. Senators Richard Blumenthal and Josh Hawley have reached out to UnitedHealthcare, CVS, and Humana, seeking detailed documentation on these practices following the findings by HHS OIG.

The Senators expressed their concern about previous Permanent Subcommittee on Investigations (PSI) findings, which noted that insurers like Humana frequently denied post-acute care for patients, a challenge that persists. Blumenthal and Hawley questioned insurers' claims about reducing prior authorization burdens in light of recent report findings.

Gaps in data reporting make it challenging to fully assess the scope of care denials under the Medicare Advantage program. This underscores the necessity for enhanced reporting to fully understand the impact of prior authorization practices on patient access to essential healthcare services.

The HHS OIG reports exposed that major Medicare Advantage insurers, such as Humana, have significantly higher denial rates for admissions to certain post-acute care facilities compared to smaller insurers. For instance, Humana denied 72 percent of inpatient rehabilitation facility requests, whereas smaller insurers averaged a 41 percent denial rate, raising concerns about the application of coverage criteria.

Further findings revealed significant initial denial rates for skilled nursing facility requests by insurers, including Humana, frequently overturned upon appeal. This appeals process suggests that denials might obstruct access to medically necessary services, risking patient harm.

Investigations previously suggested that insurers utilize artificial intelligence to drive prior authorization decisions, potentially pressuring human reviewers to follow machine recommendations. This reliance on AI in decision-making presents risks to patient care within Medicare Advantage plans.

As federal expenditures for Medicare Advantage enrollees are anticipated to surpass those for traditional Medicare, the need for oversight and accountability in prior authorization practices is stressed. The Senators have requested specific data from the insurers to assess their practices in covering post-acute care for seniors, aiming to clarify the extent of prior authorization denials and ensure alignment with patient needs and regulatory compliance.
