Prior Authorization Rx (PARx)

PARx (Prior Authorization Rx) is a web-based electronic pharmacy​ TAR submission system. It is for pharmacy providers adjudicating claims through MedI​mpact, PHC's contracted Pharmacy Benefit Manager (PBM).

Use the prior authorization forms only if:

    • Your location is not contracted with MedImpact for claim
      adjudication (you bill PHC directly), or
    • Your location does not yet have access to PHC Electronic TAR, or
    • You are experiencing technical difficulties with internet access​​
