Emergency Care


Emergency services include: medical services and medically necessary ancillary services furnished in the hospital emergency department that are required to evaluate, treat, and stabilize an individual's emergency condition, medical or accidental, as directed or ordered by a physician in accordance with hospital protocol.

Hospitals providing emergency care are required to provide an appropriate medical screening examination. Triage is not an equivalent of a medical screening examination. The decision to treat the individual is made by the examining physician(s) or other qualified medical person actually caring for the individual at the treating facility, not the managed care plan.

An emergency condition is defined by a "prudent layperson", who possesses an average knowledge of health and medicine, as a medical condition that develops itself by symptoms of sufficient severity, including severe pain. Failure to provide such treatment could reasonably be expected to result in:


BlueCross BlueShield of Tennessee recognizes the need for access to emergency care. Emergency care is medically necessary if the individual has one or more of the attached medical diagnoses. (See Medical Appropriateness below.)

Treatment of a chronic condition in which subacute symptoms have existed over a period of time is not medically necessary for emergency care unless symptoms suddenly become severe enough to require immediate medical assistance regardless of the hour of the day or night.


If the “principal” diagnosis (discharge/final diagnosis; CMS 1450 [UB-04] form locator 67) is not on the diagnosis list, then the “admitting” diagnosis (presenting symptoms; CMS 1450 form locator 69) must be considered when determining medical necessity of an emergency.
