Qualified entities contact the MO HealthNet Service Center for DCNs. MO HealthNet Service Center staff must carefully screen the applicant and provide a DCN if known, or assign a DCN if the applicant is not known to FSD. MO HealthNet Service Center staff must also review IPAR and MXIX or IXIX screens for persons with DCNs to determine if the PE applicant received PE in the past 12 months. PE may only be granted one time in a 12 month period. If the applicant received PE in the past 12 months, the MO HealthNet Service Center staff informs the provider that this applicant is not PE eligible, as he or she received PE in the past 12 months. PE for Children is indicated by Case ID or type of assistance (TOA) code of PC (Presumptive Eligibility for Children) on IPAR, MXIX and IXIX. The IPAR screen shows a case status of active or closed along with a closing date. The MXIX and IXIX screens show the case status as well as start and stop dates. If the PE case has been active in the 12 months prior to the screening date, the applicant is not eligible for presumptive eligibility.
