After-Hours Clinic

After-Hours Clinic

The Memorial Medical Group (MMG) After-Hours Clinic is not urgent care but a clinic providing personalized, short-term treatment for MMG patients with injuries or illness. The After-Hours Clinic is open to patients ages two and up.

You can call the After-Hours Clinic for anything that you would normally call your physician’s office about. If you are experiencing symptoms of a heart attack, stroke or other emergent medical condition, you should call 9-1-1 and seek treatment at the nearest emergency department.

To schedule an appointment with the After-Hours Clinic, call ONE Call at (618) 767-7000. Walk-in patients will also be seen, but you may experience a longer wait because those with appointments will be treated first. 

The After-Hours Clinic costs the same as a visit to your physician’s office, which depends on your specific insurance plan.
