TWO-DIGIT QUALIFIERS
The shaded fields in boxes 17a, 24I, 24J, 32b and 33b should be used to report provider numbers other than the NPI as needed. Fields 17a and 24I include a separate space for a two-digit qualifier that describes the type of identifier entered. (See “Two-digit qualifiers” for a list.) Fields 32b and 33b do not have a separate area for the qualifiers, but the qualifier should still be the first two digits entered.
These two-digit qualifiers should be used as appropriate in fields 17a, 24I, 32b and 33b of the revised 1500 claim form.
