Why Insurers Deny Claims (The Reality)

Stated Reasons:
  • Protecting members from ineffective treatments
  • Following evidence-based medicine guidelines
  • Ensuring appropriate use of healthcare resources
  • Adhering to plan terms and coverage limits
Financial Reality:
  • Denied claims improve profitability and stock prices
  • Most patients don't appeal (only 1 in 10 appeal)
  • AI systems auto-deny based on cost, not medicine
  • Bonus structures reward claim reviewers for denials

Key Insight: Studies show that 50-80% of insurance denials are overturned on appeal, revealing that many initial denials lack legitimate medical justification.
