Life-Threatening Critical Care & Resuscitative Care

Life-Threatening Critical Care & Resuscitative Care
These are two types of critical care provided during emergency situations. Life-threatening critical care applies when a patient is critically ill or injured and has a serious impairment of one or more vital organs that may lead to organ failure.

Billing Codes: G521, G522, G523

Note: Up to 3 physicians can bill G521 for the same patient on the same day. If a 4th physician provides this service, they must bill G395 instead.

Resuscitative Care

Resuscitative care is provided in an emergency when the patient does not meet the criteria for life-threatening critical care but is still at risk of:

  • Loss of life
  • Loss of a limb
  • Requiring life-threatening critical care

Billing codes: G395, G391
