ICD-10-CM Code I44.2
Atrioventricular block, complete

Billable Code
Billable codes are sufficient justification for admission to an acute care hospital when used a principal diagnosis.
| ICD-10 from 2011 - 2016

I44.2 is a billable ICD code used to specify a diagnosis of atrioventricular block, complete. A 'billable code' is detailed enough to be used to specify a medical diagnosis.

The ICD code I442 is used to code Atrioventricular block

An atrioventricular block (AV block) is a type of heart block in which the conduction between the atria and ventricles of the heart is impaired. Under normal conditions, the sinoatrial node (SA node) in the atria sets the pace for the heart, and these impulses travel down to the ventricles. In an AV block, this message does not reach the ventricles or is impaired along the way. The ventricles of the heart have their own pacing mechanisms, which can maintain a lowered heart rate in the absence of SA stimulation.

Atrioventricular block, complete (exact match)

This is the official exact match mapping between ICD9 and ICD10, as provided by the General Equivalency mapping crosswalk. This means that in all cases where the ICD9 code 426.0 was previously used, I44.2 is the appropriate modern ICD10 code.
