Campus map details: entrances, buildings, registration, imaging, chapel, and pharmacy

The official campus map helps patients understand why a single street address is not enough. The St. Mary’s campus includes the hospital plus multiple medical buildings and parking areas.

Campus item Where it appears on the map Why it matters
Main entrance First floor hospital area near lobby, patient registration, cashier, chapel, pain care, lounge, wound center, and internal medicine clinic. Use this for many scheduled visits unless your instructions say ED, same-day surgery, imaging, or another building.
Emergency entrance Near the Emergency Department and emergency parking lot, with access from the Ethel Road side. Use this for emergency room visits rather than the main lobby.
Hospital imaging Imaging, radiology reception, nuclear medicine, and SSM Health Imaging West appear around the campus map. Call Imaging at 314-768-8250 and confirm which imaging desk or building applies.
6400 Medical Building The map labels oncology, infusion center, and open MRI inside or near the 6400 Medical Building. Do not assume every appointment is inside the main hospital tower.
1035 Medical Building The map labels LabCorp and Clayton Health Services Pharmacy in the 1035 Medical Building. Helpful for pharmacy pickup or lab-related routing after a visit.
1027 Medical Building The map labels Heart & Vascular Maternal & Fetal Center, Vascular Access Center, and Behavioral Health. Maternal-fetal, vascular, and behavioral health appointments may have different parking and entrance instructions.
Same-day surgery The first-floor map shows same-day surgery registration near the emergency parking area. Follow procedure instructions closely for arrival, fasting, registration, and responsible adult driver rules.
Chapel and cashier The first-floor map labels chapel, cashier, lobby, patient registration, and medical records. Useful for families needing spiritual care, payment questions, records, or wayfinding help.
Map link: Open the official SSM Health St. Mary’s Hospital – St. Louis campus map PDF before arrival if your visit involves imaging, surgery, maternity, pharmacy, emergency care, or a medical office building.
