1 Should we be coding cardiac arrest as a comorb if they have a past history of cardiac arrest? Or is it considered resolved? Some of us are coding it as a comorb and some of us aren't. Thanks - Brynn I think Comorbid_Diagnosis#When_not_to_code_a_dx_at_all answers this, but you say some people code it differently. Could someone who codes this as a comorbid explain why they code it? I want to flag this for my meeting with Allan to address collector questions, and I think we will need to know what the reasoning is. Ttenbergen 09:30, 2020 August 26 (CDT) I have included this code for a patient with a fairly recent arrest and also to highlight the extent of their CAD and comorbs. I would also likely include it if the admitting diagnosis is cardiac related. --Mailah Damian 13:08, 2020 September 4 (CDT) AG REPLY --- cardiac arrest is a manifestation of a disease (examples include arrythmias, coronary artery disease, acute MI, etc). Thus it should NOT be coded as a comorbid disorder

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