The most common claim denials are generally linked to missing, incorrect, or incomplete claim information, such as patient demographics, insurance details, subscriber information, or required claim fields. Eligibility problems, missing prior authorization, coding errors, medical necessity issues, and timely filing are also frequent causes. The exact denial pattern varies by payer and specialty.
For practices using medical billing services, identifying the reason behind a denial is only the first step. The billing team should determine why the claim failed, correct the underlying issue, and prevent the same problem from recurring.
Why Do Medical Claims Get Denied?
Common causes include:
- Incorrect or missing information: Errors in patient demographics, member IDs, provider information, or claim fields can cause a payer to reject or deny a claim.
- Eligibility and coverage issues: The patient’s coverage may have expired, changed, or excluded the service.
- Prior authorization problems: A payer may require authorization before a procedure, treatment, or service is provided.
- Medical necessity: The payer may determine that the submitted documentation or diagnosis does not support the service.
- Coding errors: Incorrect CPT, ICD-10, modifiers, units, or diagnosis-to-procedure relationships can lead to payment problems.
- Timely filing: Claims submitted after the payer’s filing deadline may be denied.
How Can Practices Prevent Common Claim Denials?
The strongest approach is to prevent errors before the claim reaches the payer. This starts with accurate eligibility verification, checking authorization requirements, reviewing documentation, and validating CPT and ICD-10 coding.
A proper claim scrubbing process can identify missing fields, coding inconsistencies, demographic errors, and other issues before submission.
A Real-World Example
Suppose an orthopedic practice schedules a procedure for a patient with a commercial insurance plan. The patient’s eligibility is active, but the procedure requires prior authorization. If the authorization is not obtained before the service, the claim can be denied even when the CPT and ICD-10 codes are otherwise correct.
An experienced billing team should identify authorization requirements during the front-end verification process rather than waiting for a denial.
What Should You Do After a Claim Is Denied?
First, review the payer’s denial reason and adjustment code. Next, determine whether the problem is related to eligibility, authorization, coding, documentation, medical necessity, or timely filing. Correct the issue when appropriate, submit supporting documentation or an appeal when necessary, and track the claim through resolution.
