Emergency cover in Catonsville, explained
One practice in Catonsville offers emergency services, though none post 24-hour hours, so cover depends on when your emergency happens. Phone before you set off in every case. Hospitals divert when their ICU is full, overnight staffing changes, and posted hours are the first thing to go stale in any directory — including this one.
Before you drive: what "emergency", "24-hour" and "out-of-hours" actually mean, the symptom triage list, and what happens when you arrive.
