Located above Safeway and across from Prince George's Plaza Metro Station, MedStar Health Urgent Care in Hyattsville is open 7 days a week. Walk-in visits are welcome, but online check-in is recommended. We offer care to people of all ages with laboratory services on-site, providing care that is beyond the scope or availability of the typical primary care practice or clinic. PARKING DIRECTIONS: Please drive to the second level of the garage to park on the top deck near our front door.
