As a service to readers, The Weekly, has compiled a guide to emergency facilities near your home and -- since emergencies can occur when you're on the road or at work -- throughout the metropolitan area.

The guide includes addresses and telephone numbers, basic fees and estimated waiting times. In some cases, where facilities have special services, you will find that information under Of Note.

All emergency rooms have at least one physician on duty 24 hours a day, and specialists on call. At some hospitals the physician may be a resident -- that is, a doctor who has earned a medical degree and served internship, and is training in a specialty, such as surgery.

Emergency-room physicians are not available for follow-up care, but the emergency department will notify your private physician and will send your records to your doctor. If you do not have a private physician, the emergency department will refer you to a doctor affiliated with the hospital who specializes in the kind of care you need. For example, if you come to the emergency room with a broken ankle, you may be referred to an orthopedist for follow-up care. Several hospitals offer follow-up care at one of their clinics. Where this service is available, it is noted in the guide.

Administrators of all emergency rooms say immediate attention is given patients whose lives are in danger. Those whose problems are less urgent may have to wait longer to be treated. Waiting times at each facility vary, depending on the time of day and the patient load at the time. This information is noted in the guide.

The fees at most facilities are broken down into two major categories -- a fee charged by the emergency room and a fee charged by the physician. In addition, patients can expect to pay extra for X-rays, cast, medication, consultation with a specialist and similar services. Fees for public ambulance services, which range from no charge to $35 depending on jurisdiction, are charged separately.

All information on fees, busy hours and special services or facilities was provided by hospital administrators. District of Columbia

Capitol Hill Hospital, 700 Constitution Ave. NE; 269-7573.

Problems in the hospital's emergency room last year caused Capitol Hill to have its license reduced to "provisional." Since then, a new emergency department team has been hired and other equipment and staffing changes have been made. Earlier this year, the hospital, including its emergency department, was fully accredited.

Peak times, according to Dr. Jeffrey A. Weisberg, director of the emergency department, vary but often begin early, 7 a.m. or 8 a.m. Early afternoon through midnight is the busiest time.

Basic fees in the emergency room are $20 for routine care, $30 for intermediate care and $50 for complicated care. Physicians' fees begin at $20 and increase on a similar sliding scale. "If a visit is super simple -- a patient comes in for a tetanus shot -- the fee will be even less, probably $10," Weisberg said.
