| 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. |
|
| I46.8 | Cardiac arrest due to non-cardiac causes | Use when cardiac arrest is due to non-cardiac causes. |
|
| I46.9 | Cardiac arrest, unspecified | Use when no specific cause of cardiac arrest is documented. |
|
| Z86.74 | Personal history of sudden cardiac arrest | Use for patients with a documented history of cardiac arrest. |

Clinical Decision Support
Always review the patient's clinical documentation thoroughly. When in doubt, choose the more specific code and ensure documentation supports it.

Essential facts and insights about Cardiopulmonary Arrest
Primary ICD-10-CM Codes for cardiopulmonary arrest
Decision Criteria
clinical Criteria
- Presence of cardiac etiology like MI or heart failure
Applicable To
- Cardiac arrest due to myocardial infarction
- Cardiac arrest due to heart failure
Excludes
- Cardiogenic shock (R57.0)
Clinical Validation Requirements
- ECG showing VT/VF
- Elevated troponin (>0.4 ng/mL)
Code-Specific Risks
- Misidentifying the underlying cardiac condition
Coding Notes
- Ensure the underlying cardiac condition is documented and coded first.
I46.8 - Cardiac arrest due to non-cardiac causes
Use when cardiac arrest is due to non-cardiac causes.
Applicable To
- Cardiac arrest due to sepsis
- Cardiac arrest due to hypoxia
Excludes
- Cardiogenic shock (R57.0)
Clinical Validation Requirements
- ABG with pH <7.2, lactate >4 mmol/L
- Documented sepsis or respiratory failure
Coding Notes
Ensure the non-cardiac cause is documented and coded first.
I46.9 - Cardiac arrest, unspecified
Use when no specific cause of cardiac arrest is documented.
Applicable To
- Cardiac arrest NOS
Excludes
- Cardiogenic shock (R57.0)
Clinical Validation Requirements
- Absence of identifiable cause after workup
Coding Notes
Use only when no specific cause is documented.
Z86.74 - Personal history of sudden cardiac arrest
Use for patients with a documented history of cardiac arrest.
Applicable To
- History of cardiac arrest
Clinical Validation Requirements
- Documented history of prior cardiac arrest
Coding Notes
Use as a secondary code to indicate history.
Ancillary Codes
Additional codes that should be used in conjunction with the main diagnosis codes when applicable.
Differential Codes
Alternative codes to consider when ruling out similar conditions to the primary diagnosis.
Documentation & Coding Risks
Avoid these common documentation and coding issues when documenting Cardiopulmonary Arrest to ensure proper reimbursement, maintain compliance, and reduce audit risk. These guidelines are particularly important when using ICD-10 code I46.2.
Impact
Clinical: Inaccurate patient records, Regulatory: Non-compliance with documentation standards, Financial: Potential reimbursement issues
Mitigation Strategy
Use detailed templates for documentation., Train staff on documentation requirements.
Impact
Reimbursement: Potential underpayment due to unspecified coding, Compliance: Non-compliance with coding guidelines, Data Quality: Decreased accuracy in clinical data
Mitigation Strategy
Use I46.2 or I46.8 based on the documented cause.
Impact
Reimbursement: Incorrect DRG assignment, Compliance: Violation of coding rules, Data Quality: Inaccurate clinical representation
Mitigation Strategy
Always code the underlying condition first.
Impact
Incorrect sequencing of cardiac arrest and underlying conditions.
Mitigation Strategy
Ensure training on proper sequencing rules.
Documentation errors, coding pitfalls, and audit risks are interconnected aspects of medical coding and billing. Addressing all three areas helps ensure accurate coding, optimal reimbursement, and regulatory compliance.
