What should be verified before resubmitting a denied claim using the CMS-1500?

• A. The patient’s previous treatment dates
• B. The reason for the denial
• C. The insurance company's office hours
• D. The severity of the medical condition

Answer: (B)

Verifying the reason for the denial is crucial before resubmitting a claim using the CMS-1500 form. Understanding why the initial claim was denied allows the healthcare provider or biller to address the specific issue, whether it was due to lack of information, incorrect coding, or coverage issues. By identifying the denial reason, the resubmission can be accurately adjusted to provide the necessary documentation or correct any errors that led to the previous denial. This step increases the likelihood of an approved claim upon resubmission, ultimately improving the cash flow for the practice.

In contrast, although knowing the patient’s previous treatment dates, the insurance company's office hours, or the severity of the medical condition might be useful in specific contexts, they do not directly address the core issue of why the claim was denied. Hence, those factors do not provide the necessary insights needed for a successful resubmission.
