HCFA-1500 Box 9b - Reserved For NUCC Use

On the current HCFA-1500 form (version 02/12), box 9b is marked as Reserved for NUCC Use. In earlier versions of the form, this box was used to collect the other insured’s date of birth and sex, typically when the patient was covered under a secondary health insurance policy through a spouse or parent.

However, with the adoption of the updated form and electronic claim standards, this data element has been deprecated. The other insured’s date of birth and sex are no longer required in professional claims and are not included in the X12 837P transaction format.

Tip: If box 9 is populated, you must still mark box 11d ("Is there another health benefit plan?") and complete the other related fields — 9, 9a, and 9d — but box 9b should be left blank.

In our example below, box 9b is shown with the placeholder label "Reserved for NUCC Use", which should remain untouched during claim submission unless specifically directed otherwise by a payer or trading partner.

Note: HCFA Box 9b is reserved for NUCC use and should not be completed. It does not map to any element in the X12 837P format, including both 4010 and 5010 versions, and including data may result in claim delays or errors.
