I44.7ICD-10-CM Code for Left bundle-branch block, unspecified I44. 7.
Left bundle branch block (LBBB) occurs when something blocks or disrupts the electrical impulse that causes your heart to beat. This block leads to an abnormal heart rhythm. A diagnosis of left bundle branch block often means that you have an underlying heart condition.
Left bundle branch block (LBBB) is an abnormal pattern seen on an electrocardiogram (ECG). More specifically, it indicates that the cardiac electrical impulse is not distributed across the heart's ventricles in the usual way.
Unspecified 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.
A simple way to diagnose a left bundle branch in an ECG with a widened QRS complex (> 120 ms) would be to look at lead V1. If the QRS complex is widened and downwardly deflected in lead V1, a left bundle branch block is present.
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.
The mortality rates were 4.5%/year for patients with LBBB, 2.5%/year for patients with RBBB, and 1.9%/year for patients without BBB (P < 0.001). Among patients with a normal SE, those with LBBB had similar mortality to those without LBBB (HR = 0.9; 95% CI: 0.4-2.2; P = 0.8).
Conditions that can cause a bundle branch block include: Congenital heart disease. Dilated cardiomyopathy. Heart attack (myocardial infarction).
LBBB has been shown to be a marker for cardiac conditions that can increase the risk of heart failure and cardiac death.

If you have bundle branch block with low heart-pumping function, you may need cardiac resynchronization therapy (biventricular pacing). This treatment is similar to having a pacemaker implanted. But you'll have a third wire connected to the left side of your heart so the device can keep both sides in proper rhythm.

Left bundle branch block is also linked to a greater risk of death after a heart attack. Some people may have left bundle branch block for many years without any problems. But a newly diagnosed left bundle branch block may mean there is some underlying heart condition that requires prompt treatment.
The mortality rates were 4.5%/year for patients with LBBB, 2.5%/year for patients with RBBB, and 1.9%/year for patients without BBB (P < 0.001). Among patients with a normal SE, those with LBBB had similar mortality to those without LBBB (HR = 0.9; 95% CI: 0.4-2.2; P = 0.8).
Unfortunately LBBB is not reversible. In your case, in the absence of any structural heart disease and symptoms, the overall risk of cardiovascular morbidity or mortality should be very low.
A left bundle branch block usually is a sign of an underlying heart disease, including dilated cardiomyopathy, hypertrophic cardiomyopathy, high blood pressure, aortic valve disease, coronary artery disease and other heart conditions. While left bundle branch block can appear in healthy people, it most often does not.
