| Code | Description | When to Use | Key Documentation |
|---|---|---|---|
| I46.9 | Cardiac arrest, unspecified | Use when the cause of cardiac arrest is not specified in the documentation. |
|
| I46.2 | Cardiac arrest due to cardiac condition | Use when cardiac arrest is directly linked to a cardiac condition. |

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 Cardiac Arrest
Primary ICD-10-CM Codes for cardiac arrest
Decision Criteria
clinical Criteria
- Absence of specific cause for cardiac arrest
Applicable To
- Unspecified cardiac arrest
Excludes
- Cardiogenic shock (R57.0)
Clinical Validation Requirements
- Documentation of cardiac arrest without a specified cause
Code-Specific Risks
- Risk of undercoding if specific cause is documented elsewhere
Coding Notes
- Ensure documentation supports the use of this code by confirming the absence of a specified cause.
I46.2 - Cardiac arrest due to cardiac condition
Use when cardiac arrest is directly linked to a cardiac condition.
Applicable To
- Cardiac arrest due to myocardial infarction
Excludes
- Cardiogenic shock (R57.0)
Clinical Validation Requirements
- Documentation linking cardiac arrest to a cardiac condition such as myocardial infarction
Coding Notes
Ensure the documentation clearly links the cardiac arrest to a specific cardiac condition.
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 Cardiac Arrest to ensure proper reimbursement, maintain compliance, and reduce audit risk. These guidelines are particularly important when using ICD-10 code I46.9.
Impact
Clinical: Leads to incomplete clinical records., Regulatory: Non-compliance with coding standards., Financial: Potential loss of reimbursement for services rendered.
Mitigation Strategy
Ensure all cases of cardiac arrest are coded, regardless of outcome., Educate staff on the importance of coding cardiac arrest in death cases.
Impact
Reimbursement: Incorrect coding can lead to improper DRG assignment affecting reimbursement., Compliance: Non-compliance with coding guidelines can result in audit issues., Data Quality: Impacts the accuracy of clinical data and patient records.
Mitigation Strategy
Use I46.x for cardiac arrest and avoid R57.0 unless shock is present without arrest.
Impact
Risk of incorrect coding due to lack of specificity or improper sequencing.
Mitigation Strategy
Regular training and audits to ensure compliance with coding guidelines.
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.
