    • You may receive a 72-hour (3-day) emergency supply of a prescribed drug if a medication is needed without delay and prior authorization (PA) is not available. This applies to all drugs requiring a PA, either because they are non-preferred drugs on the Preferred Drug List or because they are subject to clinical edits. The pharmacist at your pharmacy will ultimately decide if they want to dispense the 3-day supply or not. The choice is up to the pharmacist.
    • The 72-hour emergency supply should be dispensed any time a PA cannot be fixed within 24 hours for a medication on the Vendor Drug Program formulary that is appropriate for the member’s medical condition. If the prescribing provider cannot be reached or is unable to ask for a PA, the drug store should submit an emergency 72-hour prescription.

    Medicaid Lock-In Program FAQs

    • The Lock-In Program is designed to both manage the inappropriate use of medical services and to promote safety. You may be put in the Lock-in Program if you do not follow Medicaid rules. It checks how you use Medicaid drug store services. This can include activity that can be considered dangerous, excessive, or potentially fraudulent.
    • If you are selected for the lock-in program, you must get all of your medications from a single drug store. You will get a letter from the Office of Inspector General notifying you of the drug store you are locked into and the start date. Lock-ins may range from 36 to 60 months.
    • Your Medicaid benefits will remain the same. Changing to a different health plan will not change the Lock-In status.
    • If you are locked into a drug store but have an urgent/immediate medication need that the locked-in drug store cannot meet, please contact Member Services immediately. We will review your request on a case-by-case basis.
    • Pick one drugstore at one location to use all the time.
    • Be sure your main doctor, main dentist, or the specialists they refer you to are the only doctors that give you prescriptions.
    • Do not get the same type of medicine from different doctors.
    • To learn more, call Member Services toll-free at 1-866-959-6555 (CHIP) or 1-866-959-2555 (STAR), or 1-800-659-5764 (STAR Kids) and ask to speak to a pharmacist about the Medicaid Lock-In Program.

    Additional FAQs for STAR / STAR Kids

Medicare will pay first up to the limits of its coverage. Medicaid will cover the remaining costs if within the limits of its coverage. Medicines covered under Medicare-Medicaid dual coverage may not be the same as typical Medicaid only benefits.

    If you are in a Nursing facility, they will provide you with medications.

    Additional FAQs for CHIP

    Coverage does not include contraceptive medications prescribed only for the purpose of preventing a pregnancy and medications for weight loss or gain. You may have to pay a copayment for each prescription filled depending on your income. There are no copayments for CHIP Perinate Members.

    The pharmacy cannot give you or your child birth control pills to prevent pregnancy. You or your child can only get birth control pills if they are needed to treat a medical condition.
