What Is The Icd 10 Code For Trifascicular Block?

The ICD-10 code for Trifascicular heart block is I45.3, a specific alphanumeric code used for the classification of medical conditions. This code falls under the broader category of “Diseases of the circulatory system,” as established by the World Health Organization (WHO). Trifascicular heart block is a cardiac condition characterized by abnormal electrical conduction within the heart, and ICD-10 codes like I45.3 serve as standardized identifiers to facilitate accurate medical recordkeeping, billing, and research in the field of cardiology.

A Trifascicular block, also referred to as a complete heart block, is a cardiac conduction disorder characterized by signal disruptions in the right bundle branch and both of the left fascicles that compose the left bundle branch. In this condition, the electrical signals responsible for coordinating heartbeats encounter obstacles in multiple pathways, leading to impaired heart function. It’s important to note that if blockages occur in the right bundle branch and only one of the two left fascicles, it is known as a bifascicular block. These distinctions help clinicians diagnose and manage various cardiac conduction abnormalities. This information was last updated on June 14, 2022.

Trifascicular block, often referred to as trifascicular conduction, is a cardiac conduction disorder characterized by the simultaneous presence of three distinct abnormalities in the heart’s electrical system. These abnormalities include a right bundle branch block, either a left anterior or posterior fascicular block, and a first-degree atrioventricular (AV) block, which is identified by a prolonged PR interval on an electrocardiogram (ECG).

The term “trifascicular block” can be somewhat misleading, as it implies that all three affected components are fascicles. However, the atrioventricular (AV) node itself is not a fascicle but is still involved in this condition. This combination of conduction abnormalities can lead to various clinical implications and may require careful monitoring and management by healthcare professionals to ensure proper cardiac function.
