Welcome to Optum Rx

As a MESSA member, you have access to a large network of pharmacies across Michigan. You can use the Find a network pharmacy search tool to locate a pharmacy that accepts your MESSA prescription plan.

If you need to verify which plan you have, log in to your MyMESSA account and select Benefits.

For members with plans that require home delivery of 90-day prescriptions, you can enroll in OptumRx home delivery. To get started, log in to your MyMESSA account and select Rx home delivery or call OptumRx at 1-800-788-4863, TTY 711.

You can search for a specific drug to compare prices at in-network pharmacies. You’ll also find detailed information about the medication, including common uses, possible side effects and lower cost options, if available. Start your search.

For more in-depth information on your medication, you can search the prescription drug list by a drug’s name, therapeutic class and status tier. You’ll find information on dosage, coverage, exclusions, whether a prior authorization is required and more.

For details about your MESSA prescription plan, including copayments and deductible information, log in to your MyMESSA account.
