Claim Denial Rate: How to Measure and Reduce It

Your claim denial rate can help you spot recurring billing problems. To use it well, your practice needs a clear definition, reliable records, and a plan for addressing the causes.

A denied claim often reveals an issue that began before submission. The patient’s coverage may have changed. Staff may have missed an authorization requirement. The claim may contain incorrect details, or the record may not support the billed service.

Working the denial matters. Finding where it began matters just as much.

Start with a baseline. Then address repeated causes and check whether your changes improve results.

Start With a Clear Claim Denial Rate Definition

Before setting a target, decide what your practice will measure.

Are you counting:

Claims denied on the first payer response?
Individual denied claim lines?
Denials that remain unpaid after follow-up?

These measures answer different questions. Keep clearinghouse rejections separate from payer denials.

For a claim-level measure, decide how to count partially denied claims and repeat submissions. Then apply that method consistently.

For example, suppose your team reviews a group of 1,000 unique claims that received their first payer response. If 80 meet your agreed denial definition, the initial claim denial rate for that group is 8%.

This is an illustrative calculation, not an industry benchmark.

Use the same claim group for both parts of the calculation. Avoid comparing denials received this month with unrelated claims submitted this month.

Also track the amounts affected. A frequent, low-value denial may need a different response from a less frequent issue involving costly services.

1. Check Coverage and Benefits Before Care

Coverage checks help your team identify questions before an appointment.

Review available information for:

Coverage dates
Payer or plan changes
Benefits for the planned service
Network questions
Referral requirements

If your practice uses automated checks, assign someone to resolve exceptions.

Confirm prior authorization requirements separately. An active coverage result does not show that every planned service has approval.

Repeat checks when patients report changes and according to your practice’s workflow.

Eligibility information does not guarantee payment. Other coverage, documentation, and billing requirements still apply.

For more on tracking approvals, read our Prior Authorization Specialist Guide.

2. Keep Registration Details Current

A wrong member ID, date of birth, subscriber name, or payer selection can disrupt claim processing.

Compare the current insurance card with the practice management record. At check-in, ask about changes rather than assuming the previous visit’s details still apply.

If you use card scanning or automated data capture, review fields the system could not read clearly.

Also define who updates the account and tells the billing team about changes affecting open claims.

Correcting one claim helps that account. Updating the registration process helps prevent the same issue from reaching future claims.

3. Review Coding Before Submission

Coding questions may involve procedure codes, diagnosis codes, modifiers, units, or place of service.

Focus review on areas with repeated errors or significant financial impact. These may include:

A newly offered service
A recently added provider
A payer with recurring coding edits
Claims with unresolved documentation questions

Use the clinical record and applicable billing instructions to guide corrections.

Do not add a modifier or change a code simply to obtain payment. When the record is unclear, send the question to the appropriate clinical or coding professional.

Then update the workflow when the same issue keeps returning.

4. Check Documentation Against the Service

The clinical record should accurately describe the care provided and support the billed service.

A review before submission can identify missing information while the visit is still recent.

Templates may help clinicians record relevant details. However, they should reflect what happened during the encounter.

When a payer cites insufficient documentation, identify the specific item it says is missing. Share that finding with the clinical team.

Your providers remain responsible for clinical decisions and the accuracy of clinical records.

5. Maintain Payer Instructions Your Team Can Use

Different payers may apply different coverage, authorization, and billing requirements.

Keep a reference for the payers and services that create the most work for your practice.

For each recurring issue, record:

The payer’s stated denial reason
The relevant policy or instruction
A link to the source
The date someone checked it
The appropriate response
The workflow change your team needs

Assign someone to maintain the reference. An old instruction can create new problems.

This turns denial follow-up into shared knowledge instead of leaving useful information in one employee’s inbox.

6. Give Every Denial a Next Step

A report showing denied claims does not confirm that anyone has worked them.

Each unresolved claim should have:

A documented payer response
A next action
An assigned owner
A follow-up date
Any relevant filing or appeal deadline

Depending on the issue, the next step may involve a correction, more records, payer clarification, or an appeal.

Keep the original claim and response available for review. A short account note should help another staff member understand the work already completed.

Review Claim Denial Rate Trends and Test Your Changes

Meet regularly to review recurring causes.

For each category, ask:

Where did the problem begin?
Which team owns the correction?
What will change before the next submission?
How will we check whether the change worked?

Start with a few causes your team can address. Record each change and compare later results using the same definitions.

Track these measures separately:

Initial claim denial rate: How often claims meet your denial definition on the first payer response.
Rejections: Submission issues that need correction.
Corrected or appealed claims: Work completed after an adverse response.
Final unpaid amounts: Balances that remain unresolved.
Time to payment: How long affected claims take to resolve.
Staff rework: Time spent correcting claims and following up.

A lower rate is useful, but also check payment results and workload.

Changes in payer mix, services, claim volume, or reporting methods may affect the comparison. Review those differences before attributing every improvement to one workflow change.

Set a Target That Fits Your Practice

Choose a target after reviewing your baseline and recurring causes.

If your practice chooses a claim denial rate below 5% as an internal goal, explain the measure, timeframe, and work needed to pursue it.

A target is not a promised outcome. Payer decisions and your practice’s claim mix also affect results.

Focus on progress your team can verify: fewer repeated errors, timely follow-up, clearer ownership, and less unresolved work.

Make Denial Prevention a Shared Responsibility

Denials involve more than the billing team.

Registration, authorization tracking, clinical documentation, coding, and submission all contribute to the result.

The billing team should share recurring findings with the people closest to the cause. Those teams can then improve the earlier step.

Leadership should review whether the change reduced repeat issues and whether staff need more support.

This gives each team a practical role in improving the claim denial rate.
