Denial resolution rate: how to calculate and interpret it

Hospitals that monitor denials usually track the initial denial rate: the percentage of revenue the payer rejects on first submission. It is an important indicator, but an incomplete one. It shows the size of the problem, not the hospital’s ability to solve it. The denial resolution rate fills that gap.

What the denial resolution rate is

The denial resolution rate measures the percentage of denials received that the hospital manages to reverse through an administrative appeal. It is the indicator that answers management’s practical question: of everything the payer rejected, how much did we recover?

A hospital with a 15% initial denial rate and a 70% resolution rate recovers most of what it lost on first submission. A hospital with the same denial rate and a 20% resolution rate permanently loses most of the rejected revenue. The denial rate measures exposure; the resolution rate measures how effective the recovery process is.

How to calculate the denial resolution rate

The calculation is straightforward:

Resolution rate = (amount reversed on appeal ÷ total amount denied) × 100

To apply the formula accurately, you need to define the analysis period (monthly, quarterly or annual) and consider only completed appeals, excluding those still open. Appeals in progress distort the result because the final reversed amount is not yet known.

The calculation can be done by financial value or by the number of items denied and reversed. Calculating by value is more useful for financial management; calculating by quantity is more useful for identifying patterns by denial type.

How to interpret the result

There is no universal model for the denial resolution rate. The result depends on the profile of the denials received, the quality of clinical documentation and the structure of the appeal process.

As a practical reference: administrative denials have a higher resolution rate because they depend on objective documentation fixes. Clinical denials have a lower rate because they involve challenging medical judgment. A hospital whose denial mix is mostly administrative will naturally have a higher resolution rate, even if its appeal process is equally well structured.

The Anahp Observatory 2025 (National Association of Private Hospitals) offers a reference point: accepted denials stood at 1.96% of gross revenue from health plans in 2024, the highest in the recent historical series. Accepted denials are what remains after all appeals. The higher the accepted denials, the lower the industry’s ability to recover revenue in that period.

How to use the resolution rate in management

The value of the resolution rate lies less in the number itself and more in what it reveals when broken down by segment. Three breakdowns are especially useful, in line with the main hospital billing KPIs.

By payer

Very different rates across payers indicate that the appeal process is more effective with some payers than with others. This may reflect differences in the documentation rigor required, the quality of the relationship with the auditor or the clarity of contractual rules.

By denial type

Splitting the rate among administrative, technical and clinical denials reveals where the process is effective and where it needs to improve. A low rate on administrative denials points to a failure in the documentation appeal process. A low rate on clinical denials may point to insufficient documentation or to the attending physician’s absence from the appeal.

By period

The trend over time shows whether improvement actions are working. A rising rate indicates improved effectiveness. A stable rate alongside a growing volume of denials indicates that the appeal process has not kept pace with the growth of the problem.

Resolution rate and prevention

The resolution rate measures the ability to recover revenue after a denial. But the more strategic indicator is the accepted denial rate, which measures the permanent loss. Improving the resolution rate is necessary, but the ultimate goal is to reduce the volume of denials that reach appeal.

Hospitals that combine effective internal auditing before submission with a structured appeal process work on both fronts at once: they generate fewer denials and reverse more of the ones that do occur. A high resolution rate combined with a low initial denial rate is the result of a well-managed revenue cycle.

Revised conclusion

The resolution rate measures the ability to recover revenue after a denial. But the more strategic indicator is the accepted denial rate, which measures the permanent loss. Improving the resolution rate is necessary, but the ultimate goal is to reduce the volume of denials that reach appeal.

Rivio automatically monitors the denial resolution rate by payer and by type, identifying patterns that guide both the appeal process and preventive audit actions before submission. Rivio contractually commits to reimbursing the hospital 100% if a denial is not reversed.

FAQ: frequently asked questions about the denial resolution rate

What is the denial resolution rate?

It is the percentage of denials received that the hospital manages to reverse through administrative appeals. It measures how effective the appeal process is and complements the initial denial rate, which measures the volume of denials generated.

How do you calculate the denial resolution rate?

Resolution rate = (amount reversed on appeal ÷ total amount denied) × 100. The calculation should consider only the appeals completed in the period analyzed, excluding those still open, which distort the result.

What is a good denial resolution rate?

There is no universal benchmark. The result depends on the denial profile (administrative denials have a higher resolution rate than clinical ones) and on the quality of the appeal process. The most relevant indicator is the trend over time: a rising rate indicates an improving process, regardless of the absolute value.
