What is the ICD-10 code for cardiorespiratory arrest?

The ICD-10 code for cardiorespiratory arrest is I46.9 for unspecified cardiac arrest. Use I46.2 if due to a cardiac condition, or I46.8 if due to a non-cardiac cause.

How should cardiorespiratory arrest be documented?

Document the time of arrest, witness status, initial rhythm, interventions, and ROSC time. Use templates to ensure completeness.

Compare key differences between these codes to ensure accurate selection

Code	Description	When to Use	Key Documentation
I46.9	Cardiac arrest, unspecified	Use when the cause of cardiac arrest is unknown after a thorough workup.	Non-perfusing rhythm confirmed by ECG or defibrillator Absence of pulse and respiration
I46.2	Cardiac arrest due to underlying cardiac condition	Use when cardiac arrest is directly linked to a cardiac condition like myocardial infarction.	ECG showing ST elevation Troponin levels indicating myocardial infarction
I46.8	Cardiac arrest due to other underlying condition	Use when cardiac arrest is due to a non-cardiac cause.	Documentation of non-cardiac cause such as drowning or electrolyte imbalance

Documentation & Coding Risks

Avoid these common issues when documenting Cardiorespiratory Arrest.

Omitting witness status in documentation

Impact

Clinical: Impacts understanding of arrest circumstances., Regulatory: Non-compliance with documentation standards., Financial: Potential claim denials due to incomplete records.

Mitigation

Ensure witness status is always documented., Use templates to guide documentation.

Using Z86.74 during active treatment

Impact

Reimbursement: Incorrect coding can lead to denied claims., Compliance: Non-compliance with coding guidelines., Data Quality: Inaccurate patient records and statistics.

Mitigation

Use I46.x codes until the acute phase resolves.

Coding R57.0 with I46.x

Impact

Reimbursement: Incorrect DRG assignment affecting reimbursement., Compliance: Violation of ICD-10 coding rules., Data Quality: Misleading clinical data.

Mitigation

Do not code R57.0 with I46.x due to Excludes2 note.

Incorrect sequencing of codes

Impact

Failure to sequence underlying conditions before cardiac arrest codes.

Mitigation

Educate coders on proper sequencing rules.
