How to Handle Denied Claims Using Coding Knowledge
Denied claims are a common challenge in medical billing and can lead to delayed payments or revenue loss for healthcare providers. However, with strong medical coding knowledge, these denials can be understood, corrected, and resubmitted effectively. This blog explains how to use coding expertise to handle denied claims in a structured and efficient way.
Understanding Denied Claims
A denied claim is one that has been processed by a payer but marked as unpayable due to issues like incorrect codes, missing information, or coverage limitations. These denials differ from rejected claims, which are not processed at all due to format errors.
Common reasons for claim denials include:
Invalid or mismatched ICD-10, CPT, or HCPCS codes
Lack of medical necessity
Coding not matching documentation
Billing for services not covered by insurance
Steps to Handle Denied Claims Using Coding Knowledge
1. Review the Denial Code and Explanation
Start by reviewing the Explanation of Benefits (EOB) or Remittance Advice (RA) provided by the payer. Identify the denial reason code and read the detailed message to understand why the claim was denied.
2. Compare Coding with Documentation
Go back to the patient's medical record and verify whether the services provided are correctly documented. Ensure that the diagnosis (ICD-10) and procedure (CPT/HCPCS) codes accurately reflect the care rendered.
3. Identify and Correct Coding Errors
Use your coding knowledge to spot and fix:
Incorrect modifiers
Incompatible code combinations
Upcoding or undercoding
Missing linkage between diagnosis and procedure
Correct the claim according to the payer’s guidelines.
4. Submit an Appeal or Corrected Claim
If the denial was in error or if corrections are needed:
Prepare a corrected claim with proper documentation
Include a cover letter or appeal form if necessary
Submit within the payer’s deadline for appeals or resubmissions
Tips for Reducing Future Denials
Stay updated with coding guidelines and payer-specific policies
Perform regular coding audits
Use coding tools and software to validate codes before submission
Collaborate with clinical staff to improve documentation quality
Conclusion
Handling denied claims requires a keen eye for detail and strong coding knowledge. By carefully reviewing, correcting, and resubmitting claims, coders can help recover lost revenue and improve billing efficiency. A proactive approach to coding not only reduces denials but also ensures smoother reimbursement processes for healthcare providers.
