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

• It was decided at TASK on May 22, 2024, that this diagnosis no longer has to be the Primary Admit Diagnosis, it can be but may not always be the Primary Admit Diagnosis

• Also code Targeted Temperature Management (TTM) if applicable.
• Do NOT code this as a Comorbid Diagnosis
