What does 'ed' mean? [closed]

Solution 1:

ER and ED are the same thing when considered as a place to receive emergency medical care. Of course the Emergency Department at a hospital is likely to have a number of individual Emergency Rooms or Bays.

emergency room

North American
The department of a hospital that provides immediate treatment for acute illnesses and trauma. Lexico

emergency department

North American
A casualty department; = "emergency room"; abbreviated ED. Lexico

My health insurance card lists "in-network member responsibilities" (fees) for:

Urgent Care facilities are usually separate facilities, buildings, etc. often in several locations in a community. Urgent in this case means the patient thinks the problem requires immediate attention but is not serious enough to require an ED/ER or hospital admission. However, someone might need to be transported from an Urgent Care facility to an ER/ED for treatment and/or admitted to a hospital.

Urgent Care Centers

An urgent care center is a walk-in clinic focused on the delivery of medical care for minor illnesses and injuries in an ambulatory medical facility outside of a traditional hospital-based or freestanding emergency department. Other names for similar types of facilities include, but are not limited to: after hours walk-in clinics, minute clinics, quick care clinics, minor emergency centers, and minor care clinics.
