To be eligible for a 90 day supply, Medicaid recipients must first establish compliance and tolerability of the medication. To qualify, a Medicaid recipient must have filled the prescription for the same drug and strength for three 30 day supplies within the previous 100 days.
South Dakota Medicaid has made a list of drugs available for 90 day fills on their website. The list is subject to change; South Dakota Medicaid encourages providers to review the list frequently.
