Prescription costs

MORx: help with drug costs in Missouri

Missouri's drug program, MORx (the Missouri Rx Plan), is only for people who have both Medicare and MO HealthNet, including people whose only MO HealthNet help is paying their Medicare Part B premium.

It pays half of your share of the cost of drugs your Part D plan covers. If you have Medicare but not MO HealthNet, you may qualify for Extra Help, the federal program that lowers drug costs.
