Bifascicular block
ICD-10 I45.2 is a billable code used to indicate a diagnosis of bifascicular block.
Bifascicular block is a type of intraventricular conduction delay characterized by the simultaneous blockage of two of the three major fascicles of the heart's conduction system, specifically the right bundle branch and one of the left bundle branches (either the left anterior or left posterior fascicle). Clinically, patients may present with symptoms such as syncope, palpitations, or fatigue, although some may be asymptomatic. The anatomy involved includes the conduction pathways that facilitate the electrical impulses necessary for coordinated heart contractions. Disease progression can lead to more severe conduction disturbances, including complete heart block, and may increase the risk of arrhythmias. Diagnostic considerations include electrocardiogram (ECG) findings that reveal a widened QRS complex and specific patterns indicative of bifascicular block. It is essential to differentiate this condition from other types of heart block and conduction abnormalities to ensure appropriate management and treatment.

I45.2 specifically covers bifascicular block, which includes right bundle branch block in conjunction with either left anterior or left posterior fascicular block. It is important to note that this code does not cover trifascicular block or isolated fascicular blocks.
I45.2 should be used when there is evidence of bifascicular block on an ECG. It is crucial to differentiate it from other conduction blocks, such as I45.1 or I45.3, based on the specific fascicles involved and the clinical presentation.
Documentation should include an ECG report showing the characteristic patterns of bifascicular block, clinical notes detailing the patient's symptoms, and any relevant history of cardiovascular disease or previous conduction abnormalities.
