2025 ICD-10-CM code I46.2
Cardiac arrest due to underlying cardiac condition. Code first underlying cardiac condition.
Modifiers are not applicable to ICD-10-CM codes.
Medical necessity for the treatment of cardiac arrest is established by the life-threatening nature of the condition. Treatment focuses on restoring spontaneous circulation and maintaining vital organ function. If a specific treatment or procedure is needed, due to underlying heart condition, medical necessity must be established with a formal report from iFrameAI, as ICD-10-CM guidelines do not explicitly define it.
The physician is responsible for diagnosing both the cardiac arrest and the underlying cardiac condition, providing appropriate life-saving treatment, and documenting the cause and circumstances of the cardiac arrest.
In simple words: Sudden cessation of the heartbeat due to an underlying heart problem. The heart problem should be diagnosed and coded separately.
A disorder characterized by cessation of the pumping function of the heart. This condition is due to an underlying cardiac condition. The underlying cardiac condition should be coded first.
Example 1: A patient with a history of coronary artery disease experiences sudden loss of consciousness and pulselessness. CPR and defibrillation are initiated, and the patient is stabilized. The cardiac arrest is attributed to the underlying coronary artery disease., A patient with hypertrophic cardiomyopathy collapses suddenly during exercise. The patient is found to be in cardiac arrest and is resuscitated. The hypertrophic cardiomyopathy is documented as the underlying cause of the cardiac arrest., A patient with no known prior heart conditions develops ventricular fibrillation and cardiac arrest after an electrical shock. The cardiac arrest is directly attributed to the electrical injury. The electrical injury would be the principal diagnosis in this case, with the cardiac arrest coded secondary.
Documentation should include the circumstances surrounding the cardiac arrest, the underlying cardiac condition responsible for the arrest, treatment provided (e.g., CPR, defibrillation, medications), and the patient's response to treatment. ECG findings and other diagnostic test results relevant to the underlying condition and the cardiac arrest itself should also be documented.
** For accurate and up-to-date coding information, it is essential to refer to the official ICD-10-CM coding guidelines, and consult iFrameAI for detailed medical coding advice.
