Effective January 1, 2020, the Pennsylvania Department of Human Services (DHS) implemented a statewide preferred drug list (PDL). Keystone First will follow the DHS PDL for drugs and drug classes that are included on the PDL. Keystone First will also cover additional medications that are not on the DHS PDL as a part of our Supplemental Formulary.
