  • ICD-10-AM Codes: I44, I45.0, I45.1, I45.2, I45.3, I45.4, I45.9

This is a cardiac condition where disease or injury has interfered with (delayed) the conduction of electrical impulses along the normal electric conduction pathway through the heart being the atrioventricular node, bundle of His, the left and right bundle branches and the anterior and posterior fascicles.

Is specific diagnostic evidence required to apply the SOP?No.

However, this is a complicated diagnosis usually requiring a cardiologist opinion with recourse to electrocardiography.

Are there sub-factors that require specific information? – No.
