Right fascicular block
ICD-10 I45.0 is a billable code used to indicate a diagnosis of right fascicular block.
Right fascicular block, also known as right bundle branch block (RBBB), is a condition characterized by a delay or obstruction in the electrical conduction system of the heart specifically affecting the right bundle branch. This condition can lead to a variety of clinical presentations, including palpitations, syncope, or may be asymptomatic. The anatomy involved includes the right ventricle and the conduction pathways that facilitate the coordinated contraction of the heart muscle. Disease progression can vary; while some patients may remain asymptomatic, others may develop more serious cardiac conditions, such as heart failure or arrhythmias, particularly if associated with underlying heart disease. Diagnostic considerations include electrocardiogram (ECG) findings, which typically reveal a widened QRS complex and specific patterns indicative of right fascicular block. It is crucial to differentiate RBBB from other conduction abnormalities, as treatment and management strategies may differ based on the underlying cause and associated conditions.

I45.0 specifically covers right fascicular block, which may occur in isolation or in conjunction with other cardiac conditions such as ischemic heart disease, cardiomyopathy, or congenital heart defects.
I45.0 should be used when the clinical presentation and diagnostic findings specifically indicate a right fascicular block without evidence of left-sided conduction abnormalities or other types of blocks.
Documentation supporting I45.0 should include an ECG report demonstrating the characteristic findings of right bundle branch block, clinical notes detailing symptoms, and any relevant history of heart disease.
