The Text box is for any piece of information that the insurance carrier requires. For this patient, simply type the information into the Text box and it will be entered in Box 19 on the CMS-1500 claim form. For Medicare, this is where the subluxation level(s) is/are entered. The PART exam code letters may also be entered in this box. For Medicaid, special codes are entered here. For example, for some conditions, such as backache due to pregnancy, Medicaid requires a code in box 19 such as Y-Pregnant.
