2025 ICD-10-CM code I44

Atrioventricular and left bundle-branch block.

Accurate coding requires precise identification of the type and degree of AV block or bundle branch block from the ECG.Additional codes may be required to specify associated conditions or complications.

Modifiers may be used to indicate the type of service provided (e.g., initial evaluation, subsequent evaluation). Specific modifier requirements will vary according to the situation and the payer.

Medical necessity is established by the presence of symptoms attributable to the conduction disorder (e.g., syncope, dizziness, fatigue, chest pain), or by the presence of significant electrocardiographic abnormalities that warrant monitoring or intervention.

Diagnosis and management of cardiac arrhythmias, including ECG interpretation and treatment decisions (e.g., medication, pacemaker implantation).

IMPORTANT I44.0 (Atrioventricular block, first degree) is a more specific code that falls under I44.Other related codes might include those specifying different types or degrees of AV block or bundle branch block.

In simple words: This code describes a heart problem where the electrical signals that control the heartbeat don't travel properly through the heart. This can cause the heart to beat too slowly.

I44, Atrioventricular and left bundle-branch block, represents a cardiac conduction disorder characterized by impaired transmission of electrical impulses from the atria to the ventricles, and/or the left bundle branch. This results in delayed or incomplete ventricular depolarization, potentially leading to bradycardia (slow heart rate) or other rhythm disturbances.The diagnosis requires electrocardiographic (ECG) confirmation.

Example 1: A 65-year-old male presents with dizziness and syncope. ECG reveals first-degree AV block (I44.0)., A 70-year-old female with a history of myocardial infarction is found to have a left bundle branch block (LBBB) on routine ECG monitoring.This is coded as I44., An 80-year-old patient with a pacemaker undergoes a follow-up ECG, showing persistent complete AV block, which is documented and coded as I44 (with additional clinical details as needed).

Detailed patient history, physical examination findings, electrocardiogram (ECG) tracing showing the specific type and degree of AV block or bundle branch block, and any relevant laboratory results.

** The code I44 encompasses various types of AV block and LBBB. More specific codes (e.g., I44.0, I44.1, etc.) should be used when possible to reflect the precise diagnosis.
