A witnessed or Unwitnessed Cardiac Arrest patient in ICU must also code in Cooling Protocol using BRR or XBR.

For in-hospital witnessed arrests, code as a witnessed arrest (100-2) only if event was witnessed by hospital medical staff, this does not include house keeping, maintenance or visiting family. The witnessed cardiac arrest on the wiki is speaking only of "in Hospital" arrests when it requires hospital staff to witness.

For out of hospital arrests use anyone present as a witness. The only unwitnessed arrests are if no-one is around when the person collapses and no one knows when it occurs and when CPR is delayed because no one could do it.

Coding example

The following is just one coding example. Often the rhythm that caused the arrest is the least of the patients problems. Sometimes in it is a major problem requiring pacemaker,amiodarone etc. Use normal coding instructions, the example is just that, an example.

• Example of coding arrest patient admitted to ICU from ER then sent a number of days later to a medicine ward with the following problems:
  • V. Fib. Cardiac arrest & MI, and CHF at home or in ER.
  • Admitted from ER to ICU then transferred from ICU to Med Ward.
• DX coding:
  • ICU Admit DX:

1. cardiac arrest
2. type of rhythm (if charted)
3. MI
4. CHF

• Transfer to Medicine Ward
  • Admit DX:

1. MI
2. CHF

• Primary reason to ICU was cardiac arrest. Issue resolved in ICU so arrest must not be coded as primary reason to ward when patient transferred to the ward.
• If patient is admitted directly from the ward from ER with the above admitting DX then cardiac arrest is the primary reason for admission to medicine ward from the ER.

The concept of witnessing won't be coded in ICD10

See notes under Arrest Witnessing --- Perry Grey has a different way of obtaining this info, so we no longer need to collect it.}}Has Cardiac arrest but no concept of witnessed. What should we do with this? Ttenbergen 23:24, 2017 November 13 (CST)
