Mental Health Drug Carve Out List

OHA updates this list quarterly. It lists all “mental health drugs”, as defined in OAR 410-141-3855, that are carved out of CCO pharmacy benefits and are reimbursed directly by OHA on a fee-for-service basis. This list does not determine coverage and is subject to change at any time as new drugs come to market, are discontinued, or in rare instances, are reclassified.
