ICD-10-CM Code I45.5
Other specified heart block
Billable Code
Billable codes are sufficient justification for admission to an acute care hospital when used a principal diagnosis.I45.5 is a billable ICD code used to specify a diagnosis of other specified heart block. A 'billable code' is detailed enough to be used to specify a medical diagnosis.
The ICD code I455 is used to code Sinoatrial block
The initial impulse in a heart is usually formed in the Sinoatrial (SA) node and carried through the atria, down the internodal atrial pathways, and to the Atrioventricular (AV) node. In normal conduction, the impulse would travel across the “bundle of His” (AV bundle), down the bundle branches, and into the Purkinje fibers. This would depolarize the ventricles and cause them to contract.

Sinus rhythm (rate = 65/min) with Type II S-A (exit) block, (see laddergram). Note that the long cycles (191) are nearly identical to twice the short cycles (190).

Equivalent ICD-9 Code GENERAL EQUIVALENCE MAPPINGS (GEM)
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 426.6 was previously used, I45.5 is the appropriate modern ICD10 code.
