Which box must specifically indicate the number(s) that point to the diagnosis code(s) for charges?

The box that must specifically indicate the number(s) that point to the diagnosis code(s) for charges is Box 24E. This box is part of the CMS-1500 claim form used for submitting medical claims for reimbursement.

In Box 24E, the provider needs to enter the specific reference numbers that correlate with the diagnosis codes listed in Box 21. This clearly links the services provided to the relevant diagnoses, ensuring that the claims are processed accurately.

Providing the appropriate numbers in Box 24E is essential for the insurance company to understand the connection between the services billed and the diagnoses made, thereby facilitating proper reimbursement. This precise documentation helps to prevent delays and denials in payment due to discrepancies or missing information.
