2025 ICD-10-CM code I45.6
(Active) Effective Date: N/A Revision Date: N/A Deletion Date: N/A Diseases of the circulatory system - Other forms of heart disease Diseases of the circulatory system (I00-I99) Feed
Pre-excitation syndrome, characterized by premature ventricular contractions due to an accessory atrioventricular conduction pathway.
Modifiers may be applicable depending on the specific circumstances of the encounter. Consult the current CPT and ICD-10-CM coding guidelines for accurate modifier application.
Medical necessity for coding I45.6 is established through the presence of symptoms (e.g., palpitations, dizziness, syncope) and/or objective findings (ECG abnormalities confirming pre-excitation). The severity of symptoms and risk of complications will determine the necessity of further investigation and treatment.

In simple words: Pre-excitation syndrome means your heart's electrical signals take a shortcut, causing it to beat too fast sometimes.This can lead to a rapid or irregular heartbeat, which might cause symptoms like palpitations.
Pre-excitation syndrome (I45.6) is a cardiac condition where an accessory pathway (e.g., Bundle of Kent) creates abnormal electrical communication between the atria and ventricles. This leads to premature ventricular contractions, manifesting as a shortened PR interval and a widened QRS complex with a delta wave on electrocardiogram (ECG).Commonly associated with Wolff-Parkinson-White syndrome, it can cause palpitations, tachycardia, and potentially life-threatening arrhythmias.
Example 1: A 25-year-old presents with palpitations and occasional dizziness.ECG reveals a short PR interval, a widened QRS complex with a delta wave, consistent with Wolff-Parkinson-White syndrome (a type of pre-excitation syndrome)., A 50-year-old with a history of pre-excitation syndrome experiences a rapid, irregular heartbeat (tachycardia).This necessitates further investigation and potential treatment to prevent complications., A 60-year-old patient undergoes an electrophysiology study that confirms the presence of an accessory pathway causing pre-excitation syndrome.This leads to the recommendation of a catheter ablation procedure.
Detailed patient history, including symptoms and duration;ECG findings showing characteristic changes (shortened PR interval, widened QRS with delta wave);results of any electrophysiology studies;treatment plan and response to treatment.
** This code is used for diagnosis only.Additional codes are necessary for procedural interventions or treatments for pre-excitation syndrome.Always refer to the latest ICD-10-CM guidelines for accurate coding.
