The eRx software is capable of receiving electronic prescriptions for non-formulary medications. If CHCS determines that an electronic prescription is for a non-formulary drug (which is determined by the formulary status in the CHCS Formulary Management (FRM) file), that prescription will be placed in the CHCS holding queue for pharmacy intervention. Commercially, civilian providers are able to select and transmit any medications within their Electronic Health Record (EHR).
