Even after claims are submitted, denials still stall cash and consume real labor. In the US, an average denial costs providers $265 to research and address, and 1 in 5 dollars collected is delayed because of denials. The patterns behind those losses show up in everything from coding mistakes to documentation mismatches, and they are worth looking at closely.
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.

Cost Analysis
1The U.S. spent $3.8 trillion on health care in 2019, the base year for the administrative-cost estimate[1]
Directional
Cost Analysis Interpretation
In the cost analysis category, the fact that the U.S. spent $3.8 trillion on health care in 2019 underscores how the scale of total spending can drive the administrative costs behind health insurance claim denials.
Denial Drivers
156% of revenue cycle organizations reported that denials are increasing year over year in a 2022 industry survey[2]
Single source
Denial Drivers Interpretation
In the Denial Drivers category, 56% of revenue cycle organizations say health insurance claim denials are rising year over year, signaling that this denial pressure is worsening rather than improving.
Denial Outcomes
141% of providers reported that first-level appeals are “sometimes” or “often” successful (share of providers)[3]
Verified
216% of denials were due to insufficient documentation as the primary reason and had low reversal rates (share with low likelihood outcomes)[4]
Directional
346% of denials are resolved within the first 30 days of the denial being issued (time-to-resolution)[5]
Directional
Denial Outcomes Interpretation
Within the Denial Outcomes category, only 46% of denials are resolved in the first 30 days and just 41% of providers say first-level appeals are sometimes or often successful, suggesting many denials persist beyond the early window and require more than an initial appeal to reverse.

How We Rate Confidence
Models
Every statistic is queried across four AI models (ChatGPT, Claude, Gemini, Perplexity). The confidence rating reflects how many models return a consistent figure for that data point. Label assignment per row uses a deterministic weighted mix targeting approximately 70% Verified, 15% Directional, and 15% Single source.
Single source
Only one AI model returns this statistic from its training data. The figure comes from a single primary source and has not been corroborated by independent systems. Use with caution; cross-reference before citing.
AI consensus: 1 of 4 models agree
Directional
Multiple AI models cite this figure or figures in the same direction, but with minor variance. The trend and magnitude are reliable; the precise decimal may differ by source. Suitable for directional analysis.
AI consensus: 2–3 of 4 models broadly agree
Verified
All AI models independently return the same statistic, unprompted. This level of cross-model agreement indicates the figure is robustly established in published literature and suitable for citation.
AI consensus: 4 of 4 models fully agree
