Preferred Drug List

for CCHP Members

Search Online Formulary

The Formulary or Preferred Drug List (PDL) is only a listing of preferred medications; if your provider has clinical reasons to choose a second line agent, they will need to complete a prior authorization form and contact the health plan. For Medi-Cal members, your provider should contact Medi-Cal Rx. For our other members please refer to your "Evidence of Coverage" (EOC) for information about co-pays and exclusions to coverage for your specific situation. Most over-the-counter (OTC) medication is not covered, except where specified, and medical supplies and devices are not included in the PDL.
