Why 41% of Providers Now Report Denial Rates Over 10%, and What Is Actually Driving It
In recent industry surveys, 41% of providers report denial rates above 10%. That is a significant climb from the historical industry average of roughly 5% to 10%, and it represents a real change in the operating environment, not a statistical quirk.
The temptation is to blame any single cause. The reality is that three structural shifts are happening simultaneously, and each is contributing to the rise. Understanding which ones matter for your practice is the first step to addressing them.
Shift 1: Payers Are Tightening Their Edits
Payer denial behavior has changed measurably over the past few years. Medical loss ratios have climbed industry-wide, and payers are responding by tightening their adjudication. That shows up in a few specific ways:
- More aggressive medical necessity reviews, particularly for post-acute care, behavioral health, oncology, and diagnostic imaging.
- Tighter step-therapy and prior authorization requirements for higher-cost services and pharmaceuticals.
- More frequent updates to payer-specific edit rules, with shorter notice cycles for providers and clearinghouses.
- Increased use of AI and automation in claims review, which can flag patterns at scale that human reviewers would have missed (or approved).
None of these are new behaviors. What is new is the pace and scale. A payer that used to update edit rules quarterly may now be updating monthly. A practice or clearinghouse that does not keep current is behind almost immediately.
Shift 2: Coverage Volatility Is Producing More Eligibility-Related Denials
The OBBBA Medicaid changes are starting to ripple through. Work requirements for the expansion population went into effect in early 2026, and six-month redeterminations begin at the end of December 2026. The downstream effect for practices: more patients losing or changing coverage between visits, more eligibility-related denials when claims are filed against coverage that lapsed between the appointment and the date of service.
Commercial coverage is also more volatile than it used to be. Higher job-switching rates, more frequent plan changes during open enrollment, expanded use of high-deductible plans, all create more situations where the coverage on file is not the coverage in effect on the date of service.
Eligibility-related denials are largely preventable, but they require a workflow change. The practices that have updated their pre-visit verification cadence are not seeing the same climb in this category as the practices still running on the old model.
Shift 3: Prior Authorization Volume and Complexity Are Both Rising
Prior authorization remains one of the largest single sources of claim denial pressure. The volume of services requiring PA has continued to climb. Payer rules around documentation requirements have gotten more specific. The 80% appeal overturn rate documented in the recent CMS-0057-F disclosures suggests that many of the denials being issued are not even holding up to review, but the burden of appealing falls on the practice.
CMS-0057-F is starting to add structure (specificity requirements, faster decision timelines, public reporting), but the underlying volume problem has not gone away. Practices that have not yet built a payer-tier appeal strategy are absorbing more PA-driven denial activity than they need to.
What This Means for Your Operation
If your denial rate has climbed in the past 18 months, it is almost certainly some combination of the three shifts above. The first task is figuring out which ones are driving your specific climb. That requires denial-rate visibility by payer, by denial reason, and by trend over time.
A few questions to ask of your data:
- Has your denial rate climbed evenly across all payers, or is it concentrated in a few? Concentrated climbs usually point to payer-specific edit changes.
- Has your eligibility-related denial volume climbed? If yes, the workflow upstream is the lever, not the appeal queue downstream.
- Has your prior authorization denial volume climbed? If yes, the appeal strategy and PA submission workflow are the levers.
- Is your clean claim rate (first-pass acceptance) still where it was 18 months ago? If it has slipped, the scrubbing layer is behind the payer edit changes.
Where Clearinghouse Quality Shows Up
Each of the three shifts above is at least partially mitigable through stronger clearinghouse infrastructure. Tighter payer edits are countered by continuously updated edit rules in pre-submission scrubbing. Eligibility-related denials are countered by faster, more comprehensive real-time eligibility verification. PA-driven denials are countered, in part, by attachment workflows that ensure complete clinical documentation is submitted with the claim.
The clearinghouses that are keeping their clients’ denial rates flat in this environment are the ones investing in payer relationships, edit rule updates, and workflow integration at a faster pace than payers are changing their behavior.
How HSC Approaches This
Harris Secure Connect has spent 26 years building the payer-specific edit depth that is increasingly the difference between flat and climbing denial rates. Our scrubbing rules update continuously based on the payer behavior our team tracks across thousands of provider connections. If your denial rate has climbed and your current clearinghouse cannot tell you why, that is a signal worth acting on.
