In most cases, your prescription drugs are filled at Memorial Hermann Advantage's network of pharmacies. A network pharmacy is a pharmacy that has a contract with the plan to provide your covered Medicare Part D prescription drugs. In most cases, your prescriptions are covered under your plan only if they are filled at a network pharmacy or through the Costco Mail Order pharmacy service. You may switch to any network pharmacy to fill your prescriptions. Prescriptions can be filled at non-network pharmacies under certain circumstances as described in your Evidence of Coverage (EOC). The pharmacy network may change at any time and in some circumstances, you may be notified. To verify if a pharmacy is part of our network, please contact Customer Service at (844) 860-6750 (TTY 711). You can also download a copy of our Pharmacy Directory or visit our website's online pharmacy search tool.

Please note that due to possible changes that can occur after our Pharmacy Directory is updated, inclusion of a pharmacy in this directory does not guarantee the pharmacy is still in the network at the time of use. It also does not guarantee that the pharmacy is open or is at the same location as listed in the directory. Please reach out to your pharmacy for the most up-to-date information on their location and hours of operations. You may also contact our Customer Service for additional assistance.

Generally, we cover drugs filled at an out-of-network pharmacy only when you are not able to use a network pharmacy. To ensure that Memorial Hermann Advantage will allow an out-of-network pharmacy before you fill your prescription, call Customer Service to see if there is a network pharmacy in your area where you can fill your prescription.
If you go to an out-of-network pharmacy due to a health emergency, you may have to pay the full cost (rather than paying just your co-pay) when you fill your prescription. In the event of using an out-of-network pharmacy for an emergency, you can ask us to reimburse you for our share of the cost by submitting a paper claim form called a Direct Member Reimbursement (DMR), Spanish DMR form is available here.
However, even after we reimburse you for our share of the cost, you may pay more for a drug purchased at an out-of-network pharmacy because the out-of-network pharmacy’s price may be higher than a network pharmacy’s. Regardless of the amount, we can only reimburse you the amount that we would have paid if you had the prescription filled at a network pharmacy. Even though you may not receive the full amount you paid in reimbursement, the amount that you paid may still be counted toward your required out-of-pocket costs in reaching the catastrophic stage.
