Atrioventricular and left bundle-branch block
ICD-10 I44 is a used to indicate a diagnosis of atrioventricular and left bundle-branch block.
Atrioventricular (AV) block and left bundle-branch block (LBBB) are types of conduction disturbances in the heart's electrical system. AV block occurs when the electrical signals between the atria and ventricles are impaired, leading to a delay or complete block in conduction. This can result in symptoms such as palpitations, syncope, or even heart failure in severe cases. LBBB, on the other hand, occurs when there is a delay or blockage in the left bundle branch of the heart's conduction system, affecting the timing of ventricular contraction. Clinically, patients may present with symptoms of heart failure, fatigue, or may be asymptomatic. The anatomy involved includes the heart's electrical conduction pathways, specifically the atrioventricular node and the left bundle branch. Disease progression can vary; while some patients may remain stable, others may experience worsening symptoms or progression to more severe heart block. Diagnostic considerations include electrocardiograms (ECGs) that reveal characteristic patterns of AV block or LBBB, and further evaluation may include echocardiography or Holter monitoring to assess for underlying structural heart disease or arrhythmias.

I44 covers various degrees of atrioventricular block (first-degree, second-degree, and third-degree) as well as left bundle-branch block. Each condition has specific diagnostic criteria based on ECG findings, such as PR interval prolongation for AV block and QRS duration for LBBB.
I44 should be used when the clinical presentation specifically indicates atrioventricular or left bundle-branch block. If the condition is related to other conduction disorders without AV involvement, codes like I45 may be more appropriate.
Documentation should include ECG results showing the specific type of block, clinical symptoms experienced by the patient, and any relevant history of heart disease or prior interventions. Detailed notes on the patient's functional status and treatment plan are also essential.
