Frequently Asked Questions (FAQs)

MTM provides transportation for members of Trillium Community Health Plan who reside in Multnomah, Washington, and Clackamas counties.

For routine medical appointments, we recommend calling at least 24 hours in advance. For urgent trips and hospital discharges, we will attempt to schedule based on transportation provider availability.

MTM’s customer service center is open Sunday through Saturday from 8 a.m. to 5 p.m. PT for routine scheduling.

For hospital discharges or urgent trips, we are open 24/7/365

An urgent trip is an unscheduled episodic situation in which there is no immediate threat to life or limb, but the member must be seen on the day of the request and treatment cannot be delayed until the next day. This may also include hospital discharges and pharmacy visits.

Yes, MTM can schedule recurring trips, eliminating the need to schedule each trip individually. Recurring trips can be scheduled for 3 months at a time, or indefinitely if they are for dialysis.

If a member says they are unable to utilize public transportation or mileage reimbursement, a healthcare provider will be required to fill out a Level of Need form. This form communicates the member’s actual needs to MTM for appropriate mode assignment.

If the return time for an appointment is not known at the time of the reservation, MTM will assign the return trip as a will-call trip. In this case, you will call MTM when the member is ready for their ride home. We will dispatch the trip and transportation provider will arrive within one hour. Call MTM at 1-877-583-1552 to find out the status of a transportation provider’s estimated arrival time.
