What is the ICD-10 code for cardiopulmonary arrest?

The ICD-10 code for unspecified cardiopulmonary arrest is I46.9. For cardiac causes, use I46.2, and for non-cardiac causes, use I46.8.

How do you document a cardiopulmonary arrest?

Document the time of arrest, witnessed status, initial rhythm, interventions like CPR and defibrillation, and ROSC time using a standardized template.

Code Comparison: When to Use Each Code

Compare key differences between these codes to ensure accurate selection

Code	Description	When to Use	Key Documentation
I46.2	Cardiac arrest due to underlying cardiac condition	Use when cardiac arrest is due to a documented cardiac condition.	ECG showing VT/VF Elevated troponin (>0.4 ng/mL)
I46.8	Cardiac arrest due to non-cardiac causes	Use when cardiac arrest is due to non-cardiac causes.	ABG with pH <7.2 lactate >4 mmol/L Documented sepsis or respiratory failure
I46.9	Cardiac arrest, unspecified	Use when no specific cause of cardiac arrest is documented.	Absence of identifiable cause after workup
Z86.74	Personal history of sudden cardiac arrest	Use for patients with a documented history of cardiac arrest.	Documented history of prior cardiac arrest

Documentation & Coding Risks

Avoid these common issues when documenting Cardiopulmonary Arrest.

Incomplete documentation of arrest events

Impact

Clinical: Inaccurate patient records, Regulatory: Non-compliance with documentation standards, Financial: Potential reimbursement issues

Mitigation

Use detailed templates for documentation., Train staff on documentation requirements.

Coding I46.9 when a specific cause is documented

Impact

Reimbursement: Potential underpayment due to unspecified coding, Compliance: Non-compliance with coding guidelines, Data Quality: Decreased accuracy in clinical data

Mitigation

Use I46.2 or I46.8 based on the documented cause.

Incorrect sequencing of codes

Impact

Reimbursement: Incorrect DRG assignment, Compliance: Violation of coding rules, Data Quality: Inaccurate clinical representation

Mitigation

Always code the underlying condition first.

Code Sequencing

Impact

Incorrect sequencing of cardiac arrest and underlying conditions.

Mitigation

Ensure training on proper sequencing rules.
