Introduction
Claim denials are one of the largest causes of lost revenue for healthcare practices.
Even a small increase in denied claims can create cash flow issues, increase staff workload, and delay reimbursements.
Fortunately, most claim denials are preventable.
Top Reasons Claims Are Denied
1. Incorrect Patient Information
Simple demographic errors can lead to immediate claim rejection.
2. Insurance Eligibility Issues
Coverage may have expired or benefits may not include the service performed.
3. Coding Errors
Incorrect CPT, ICD-10, or HCPCS codes frequently result in denied claims.
4. Missing Documentation
Incomplete clinical documentation often leads to medical necessity denials.
5. Prior Authorization Not Obtained
Many procedures require approval before treatment.
6. Duplicate Claims
Submitting duplicate claims can trigger automatic denials.
7. Timely Filing Limits
Insurance companies require claims within specific filing deadlines.
8. Medical Necessity
Supporting documentation must justify the services provided.
9. Incorrect Modifiers
Improper modifier usage often results in payment delays.
10. Payer Policy Changes
Insurance companies regularly update billing rules.
