Health Insurance Claim Denial Statistics

With $265 spent internally to chase each denied claim and up to 3.2 staff hours lost per case, claim denials quietly drain health systems while 46% get resolved only after the first 30 days. You will see what is driving rework most often, how often appeals actually work, and which automation moves like eligibility verification and OCR for documentation can cut preventable denials by 33%.

Denials create direct costs long after a claim is submitted. Providers spend an average of $265 and 3.2 staff hours on each denied claim, and 1 in 5 collected dollars is delayed by denial-related rework. This breakdown shows where those denials come from, how often appeals work, and how quickly claims are resolved.

Key Takeaways

  • The U.S. spent $3.8 trillion on health care in 2019, the base year for the administrative-cost estimate
  • 56% of revenue cycle organizations reported that denials are increasing year over year in a 2022 industry survey
  • 41% of providers reported that first-level appeals are “sometimes” or “often” successful (share of providers)
  • 16% of denials were due to insufficient documentation as the primary reason and had low reversal rates (share with low likelihood outcomes)
  • 46% of denials are resolved within the first 30 days of the denial being issued (time-to-resolution)
  • $265 per denied claim is the estimated average internal administrative cost to research and address a denial (provider cost)
  • 3.2 hours per denied claim is the average time spent by staff to work a denial to resolution (hours per denial)
  • 1 in 5 dollars collected is delayed due to denials according to a provider financial workflow survey (share of cash delays)
  • 34% of denials are related to coding/billing errors (share of denials by reason)
  • 18% of denials are attributable to network contract and plan mismatch (share of denials by reason)
  • 46% of denials stem from mismatches between order entry and claim submission data (share by mismatch type)
  • 22% of organizations reported using OCR/AI to extract documentation for appeals (share using AI document extraction)
  • 26% of organizations reported using proactive claim pre-audit (share using pre-audit)
  • 18% of health systems use robotic process automation (RPA) for denial rework (share using RPA)

Denials cost providers time and money, with many preventable issues and fast but costly resolution cycles.

Denials: prevalence, appeal success, and resolution speed

More than half of organizations report increasing denials, while first-level appeals succeed only sometimes/oftentimes and many denials take multiple days to resolve.
