1 Maintenance medications are typically those drugs you take on a regular basis for a chronic or long-term condition.

You are not required to use OptumRx to obtain a 90-day supply of your maintenance medications, but you may pay more out-of-pocket compared to using OptumRx, your plan’s Preferred Mail Service Pharmacy. Prescription orders sent directly to OptumRx from your doctor must have your approval before OptumRx can send your medications.  This includes new prescriptions and prescription refills.  OptumRx will contact you, by phone, to get your approval.  At that time you may also tell OptumRx to automatically fill any future prescriptions they receive directly from your doctor(s) for up to one year. If OptumRx is unable to reach you for approval your prescription will not be sent to you.  Refunds may be available for prescriptions you did not approve and did not want. You may request a refund or cancel your approval by calling OptumRx at 1-800-791-7658, TTY 711, 8 a.m .8 p.m. CT, Monday – Friday.  New prescriptions should arrive within ten business days from the date the completed order is received by the Mail Service Pharmacy. Completed refill orders should arrive in about seven business days. OptumRx will contact you if there will be an extended delay in the delivery of your medications.
