ICD-10-CM Code For Atrioventricular And Left Bundle-Branch Block: Group Overview
The International Classification of Diseases, Tenth Revision, Clinical Modification (ICD-10-CM) code group I44 includes atrioventricular conduction disorders and left bundle-branch block, covering first-, second-, and third-degree atrioventricular block as well as bundle-branch conduction delays and blocks. These ICD-10-CM diagnosis codes are used to document conduction system abnormalities that affect cardiac rhythm, capture conduction severity and laterality, and reflect the need for monitoring or device therapy. Accurate coding within the ICD-10-CM I44 group supports proper claim adjudication and complete clinical documentation and appropriate reimbursement.

ICD-10-CM I44: Atrioventricular And Left Bundle-Branch Block Overview
This group includes conduction disorders affecting the atrioventricular node and the left bundle branch of the heart, which disrupt normal electrical impulse transmission and can lead to bradycardia or syncope. These diagnoses target the cardiac conduction system and are important for documenting rhythm disturbances and associated symptoms. Accurate coding matters for reimbursement because it links clinical documentation to the specific conduction abnormality treated or monitored.
