Atrioventricular block, complete
ICD-10 I44.2 is a billable code used to indicate a diagnosis of atrioventricular block, complete.
Atrioventricular block, complete, is a serious cardiac condition characterized by a total failure of electrical conduction from the atria to the ventricles. This condition results in a dissociation between atrial and ventricular contractions, leading to bradycardia and potential hemodynamic instability. The anatomy involved includes the atrioventricular (AV) node, which is responsible for transmitting electrical impulses from the atria to the ventricles. Complete AV block can be caused by various factors, including ischemic heart disease, degenerative changes in the conduction system, or inflammatory processes such as myocarditis. Disease progression may lead to syncope, heart failure, or sudden cardiac arrest if not appropriately managed. Diagnostic considerations include an electrocardiogram (ECG) that reveals a complete dissociation between P waves and QRS complexes, along with a heart rate typically below 40 beats per minute. Patients may present with symptoms such as fatigue, dizziness, or palpitations, necessitating immediate medical evaluation and intervention.

I44.2 specifically covers complete atrioventricular block, which may arise from various etiologies including ischemic heart disease, congenital heart defects, or degenerative conduction system disease. It is characterized by the absence of conduction through the AV node, leading to a complete dissociation of atrial and ventricular activity.
I44.2 should be used when there is clear evidence of complete heart block on an ECG, characterized by a lack of relationship between P waves and QRS complexes. It is crucial to differentiate it from partial blocks (I44.1) where some conduction is still present.
Documentation for I44.2 should include an ECG report confirming complete heart block, clinical notes detailing patient symptoms, and any relevant history of cardiac conditions. Additionally, treatment plans and follow-up evaluations should be documented to support the diagnosis.
