A recent analysis by the Kaiser Family Foundation (KFF) has revealed alarming statistics regarding health insurance claim denials through the federal HealthCare.gov marketplace. In 2023, nearly one-fifth of claims for in-network services were rejected, while the rejection rate for out-of-network services was even higher at 37%. This study delves into publicly available data on claim denials and appeals for individual-market plans, highlighting significant discrepancies among insurers.

The KFF analysis underscores a wide disparity in denial rates across various insurers within the HealthCare.gov platform. Some states saw in-network denial rates as low as 1%, while others experienced peaks up to 54%. Notably, several major insurers exhibited notably high denial rates. For instance, Blue Cross Blue Shield of Alabama recorded a 35% denial rate for its plans, while UnitedHealth Group stood at 33% across multiple states. Other prominent insurers with elevated denial percentages include Health Care Service Corporation, Molina Healthcare, and Elevance Health.

Insight into the reasons behind these denials reveals that the most frequent cause was attributed to an unspecified "other" category, accounting for 34% of cases. Excluded services represented 16% of denials, while issues related to lack of prior authorization or referral made up 9%. Administrative problems and exceeding benefit limits also contributed significantly to the denials.

In response to denied claims, only about 1% of consumers opted to appeal the decision in 2023. However, insurers upheld their initial rejections in more than half of these appeals. Fewer individuals proceeded to file external appeals, indicating a reluctance or lack of awareness regarding further recourse options.

This comprehensive examination of 425 million claims submitted to 175 insurers provides valuable insights into the challenges faced by healthcare consumers in navigating insurance coverage. The findings call for greater transparency and accountability from insurers to ensure fair treatment of policyholders' claims.
