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 MedImpact, 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
