I46-I46.9Primary Range
Cardiac arrest and sudden cardiac death
This range includes codes for cardiac arrest and sudden cardiac death, which are central to the diagnosis and coding of SCD.
Acute myocardial infarction
These codes are used when SCD is due to an acute myocardial infarction.

| Code | Description | When to Use | Key Documentation |
|---|---|---|---|
| I46.1 | Sudden cardiac death, so described | Use when sudden cardiac death occurs with failed resuscitation efforts. |
|
| I46.9 | Cardiac arrest, cause unspecified | Use when the cause of cardiac arrest is not specified. |

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 Sudden Cardiac Death
Primary ICD-10-CM Codes for sudden cardiac death
Decision Criteria
clinical Criteria
- Documented failed resuscitation and cardiac cause.
Applicable To
- Sudden cardiac death with failed resuscitation
Excludes
- Instantaneous death (R96.0)
Clinical Validation Requirements
- Absence of ROSC despite CPR/defibrillation
- Time from symptom onset to death ≤1 hour
Code-Specific Risks
- Incorrectly coding as R96.0 when cardiac etiology is confirmed.
Coding Notes
- Ensure documentation specifies the failed resuscitation and time frame.
I46.9 - Cardiac arrest, cause unspecified
Use when the cause of cardiac arrest is not specified.
Applicable To
- Cardiac arrest without specified cause
Excludes
- Cardiac arrest due to known cause
Clinical Validation Requirements
- Lack of specified etiology in documentation
Coding Notes
Ensure documentation attempts to identify an underlying cause.
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 Sudden Cardiac Death to ensure proper reimbursement, maintain compliance, and reduce audit risk. These guidelines are particularly important when using ICD-10 code I46.1.
Impact
Clinical: Inadequate clinical data for treatment planning., Regulatory: Potential non-compliance with coding standards., Financial: May affect reimbursement due to incorrect DRG.
Mitigation Strategy
Always attempt to identify and document the underlying cause., Use autopsy results to clarify etiology when available.
Impact
Reimbursement: Incorrect DRG assignment leading to potential underpayment., Compliance: Non-compliance with coding guidelines., Data Quality: Misrepresentation of clinical data.
Mitigation Strategy
Use I46.1 if autopsy or clinical evidence suggests a cardiac cause.
Impact
Failure to document the underlying cause of cardiac arrest can lead to audit issues.
Mitigation Strategy
Ensure comprehensive documentation of all potential causes and contributing factors.
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.
