Additional Info

• Code when
  • a non-perfusing rhythm occurs and
  • the patient is given BCLS or ACLS (i.e. receives CPR of some sort) or receives defibrillation or cardioversion
• Thus do not code this if no treatment is given for the arrest -- this is different than our usual rule to code diagnoses even if no treatment is given, and the reason is that EVERY death at some point includes the heart stopping (cardiac arrest) and we would therefore be using this code for every death, which we do not want to do.
• Combine this code with the INITIAL rhythm observed during the code, which may include:
  • Ventricular fibrillation
  • Ventricular tachycardia
  • Asystole
  • Pulseless Electrical Activity (PEA) -- also known as electromechanical dissociation
  • Could also be a supraventricular arrythmia or high degree of heart block

Could we please have some clarification around using this code and when to check as primary? example 1 patient arrests in ER, goes to OR and is admitted to ICU from the OR. Diagnosis, cardiac arrest (6-10 min downtime) abdominal compartment syndrome/obstruction/perforation/, acute liver failure from shock liver, shock, NOS when to carry it forward as an admit for subsequent profiles in the same episode of care? example 2 April 6, PEA arrest secondary to anaphylactic shock, April 19 melena, scope suspicious for ischemic gut, goes to the OR April 20 confirms gangrenous bowel/perforation, abscesses, to SICU post op (clinically in SS but doesn't have lactate high enough for our criteria) do we still include the cardiac arrest code?
