HCFA-1500 Box 9c - Reserved For NUCC Use

On the current HCFA-1500 form (version 02/12), box 9c is marked as Reserved for NUCC Use. In earlier versions of the form, this box was used to collect the employer’s name or school name of the other insured, especially when the insurance coverage was provided through employment or a student plan.

However, with the adoption of the updated form and electronic claim standards, this data element has been deprecated. Employer or school information is no longer required in professional claims and is 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 9c should be left blank.

In our example below, box 9c 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 9c 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.
