Denials are usually discovered after adjudication. However, the revenue loss often begins much earlier.
Roughly 15% of claims are initially denied, and hospitals spend nearly $19.7 billion each year appealing them — with only about half of those denials ultimately overturned. For revenue cycle leaders, the more productive question is no longer how quickly a team can work a denial after it occurs. It is where the risk entered the revenue cycle in the first place.
For most organizations, the answer is somewhere upstream.
The Financial Risk Starts Before the Claim
A registration error at intake can create an eligibility problem at billing. An authorization that does not match the service delivered creates another point of exposure. Documentation that lacks the specificity needed to support coding can compromise a claim before anyone in billing ever sees it.
In 2025, 68% of revenue cycle leaders identified inaccurate or incomplete patient data at intake as a driver of denials.
When that information isn’t corrected where it enters the workflow, the work doesn’t disappear—it moves downstream. Staff end up researching payer requirements, correcting account information, rebuilding claims, and preparing appeals for issues that could have been addressed much earlier. By then, several small gaps have compounded into a much larger reimbursement problem.
Denial prevention changes where that work happens.
Retrospective Reporting Is Not Enough
Traditional denial analytics tell leaders what has already gone wrong. A monthly report can identify which payer is generating the most denials or show where a denial category is trending upward — but by the time that pattern appears on a dashboard, the affected claims have already gone to the payer.
Nearly half of healthcare executives now identify the revenue cycle as their top area for IT investment, with growing attention to automation, artificial intelligence, and predictive analytics. The opportunity is to move from retrospective visibility to in-flight intervention — seeing a problem sooner, at a point when something can still be done about it.
Earlier Signals Give Teams More Options
The sooner a potential denial surfaces, the more choices a team has for addressing it. An eligibility discrepancy can be resolved during intake rather than after billing. Authorization mismatches can be flagged while a case is still active. On the clinical side, documentation gaps can be routed for review before they become coding or billing problems.
Claims can also be evaluated for denial risk before submission, helping staff focus closer attention on accounts that warrant it instead of applying the same level of effort across every claim.
Payer intelligence matters here too. Requirements change, documentation expectations vary, and actual payer behavior does not always mirror the written rule. A 2026 federal review of Medicare Advantage skilled nursing facility authorizations found that 97% of appealed denials issued by one major authorization contractor were ultimately overturned — a finding that underscores the importance of understanding how payer requirements play out in practice, not just on paper.
Denials Should Make the Process Better
Some denials are unavoidable. Repeating the same preventable denial is a different problem.
When a denial occurs, organizations should be able to trace it back to the workflow, decision, or data element that contributed to it. If the same authorization issue keeps appearing, getting better at appealing it is not the answer. The underlying process needs to change.
In 2025, final denials and uncompensated care contributed to a loss of more than $48 billion in net revenue across more than 2,300 hospitals — a 25% increase from the prior year. Even a modest reduction in avoidable denials can meaningfully reduce rework, support more predictable reimbursement, and preserve staff capacity for the exceptions and decisions that genuinely require judgment.
What This Means for Healthcare Organizations
Strong denial management will remain necessary. But it should not be the first line of defense. The shift toward upstream prevention requires revenue cycle teams to look beyond denial rates and appeals workflows and examine the registration, authorization, documentation, and coding processes that feed claims in the first place.
For practices and health systems looking to reduce denial volume, the starting point is identifying where risk enters the revenue cycle — and building the workflows, payer intelligence, and technology infrastructure to catch it before it becomes a denied claim.
