I44.4 is a valid billable ICD-10 diagnosis code for Left anterior fascicular block . It is found in the 2021 version of the ICD-10 Clinical Modification (CM) and can be used in all HIPAA-covered transactions from Oct 01, 2020 - Sep 30, 2021 .
Bifascicular block means the heart shows impaired conduction in two fascicles of the right and left bundles. ICD-9 coding rules: Your choice between 426.51 and 426.52 depends on whether the patient has a left posterior or left anterior fascicular block in addition to right bundle branch block (RBBB).
An electrocardiographic finding comprising right bundle branch block and left anterior fascicular block, or right bundle branch block and left posterior fascicular block. Defects occuring in two of the three divisions of the conduction system of the heart are considered bifascicular blocks.

Bundle branch block is partial or complete interruption of impulse conduction in a bundle branch; fascicular block is similar interruption in a hemifascicle of the bundle. The 2 disorders often coexist. There are usually no symptoms, but presence of either suggests a heart disorder.
I45.10ICD-10 code I45. 10 for Unspecified right bundle-branch block is a medical classification as listed by WHO under the range - Diseases of the circulatory system .
Clinically, bifascicular block presents with one of two ECG patterns: Right bundle branch block (RBBB) with left anterior fascicular block (LAFB), manifested as left axis deviation (LAD) RBBB and left posterior fascicular block (LPFB), manifested as right axis deviation (RAD) in the absence of other causes.
Left anterior fascicular block (LAFB) is considered a failure or delay of conduction in the left anterior fascicle. 1. Despite the fact that little is known about the long-term prognosis associated with LAFB, it has generally been thought of as a benign electrocardiographic (ECG) finding. 2.
A left anterior fascicular block (LAFB) also known as a left anterior hemiblock (LAHB) occurs when the anterior fascicle of the left bundle branch is no longer able to conduct action potentials. The criteria to diagnose a LAFB is as follows: Left axis deviation of at least -450.
I45.10Unspecified right bundle-branch block I45. 10 is a billable/specific ICD-10-CM code that can be used to indicate a diagnosis for reimbursement purposes. The 2022 edition of ICD-10-CM I45. 10 became effective on October 1, 2021.
Right bundle branch block (RBBB) is an electrocardiogram finding that occurs when the physiologic electrical conduction system of the heart, specifically in the His-Purkinje system, is altered or interrupted resulting in a widened QRS and electrocardiographic vector changes.
Bundle branch block is a condition in which there's a delay or blockage along the pathway that electrical impulses travel to make the heart beat. It sometimes makes it harder for the heart to pump blood to the rest of the body.
When we have right bundle branch block with either left anterior fascicular block (common) or left posterior fascicular block (less common) we call it a bifascicular block. The problem with bifascicular block is that the heart's electrical conduction system is down to one fascicle.
Is it LBBB or RBBB? Once you have identified that your QRS is wide go to lead V1. If the “terminal force” of the QRS is above the baseline (big R wave) you have a RBBB. If the “terminal force” of the QRS is below the baseline (big S wave) you have a LBBB.
Fascicular block involves the anterior or posterior fascicle of the left bundle branch. Interruption of the left anterior fascicle causes left anterior hemiblock characterized by modest QRS prolongation (< 120 millisecond) and a frontal plane QRS axis more negative than −30° (left axis deviation).
