Cardiac Arrest Prior to Hospitalization
A 67-year-old patient went into cardiac arrest at home. The patient was resuscitated by emergency medical services (EMS) and was awake and oriented upon arrival at the emergency department (ED). In the ED, the patient was placed on a cardiac monitor and pulse oximetry. An EKG was performed and confirmed a complete heart block. The patient was subsequently admitted to undergo an emergency pacemaker placement in the cardiac catheterization laboratory. Is it appropriate to assign a code from category I46, Cardiac arrest, or should code Z86.74, Personal history of sudden cardiac arrest, be assigned when a patient has a cardiac arrest outside of the hospital and is resuscitated prior to admission? ...

Article Overview
This coding article discusses an emergency and inpatient coding scenario involving cardiac arrest that occurred before hospitalization, subsequent resuscitation, and evaluation in the emergency department. It is intended for coders, billers, CDI staff, and clinical documentation teams who need to understand the relevant diagnosis coding considerations for acute and historical cardiac arrest-related reporting. The article focuses on the distinction between current-event and history-related reporting in a pre-hospital resuscitation context.
Why This Topic Matters
Pre-hospital cardiac arrest cases can affect diagnosis reporting and downstream data quality, so understanding the article helps support consistent coding for emergency department and inpatient records.
