I63.9 is a billable ICD code used to specify a diagnosis of cerebral infarction, unspecified. A 'billable code' is detailed enough to be used to specify a medical diagnosis.


The ICD code I63 is used to code Cerebral infarction

A cerebral infarction is a type of ischemic stroke resulting from a blockage in the blood vessels supplying blood to the brain. It can be atherothrombotic or embolic. Stroke caused by cerebral infarction should be distinguished from two other kinds of stroke: cerebral hemorrhage and subarachnoid hemorrhage. A cerebral infarction occurs when a blood vessel that supplies a part of the brain becomes blocked or leakage occurs outside the vessel walls. This loss of blood supply results in the death of tissue in that area. Cerebral infarctions vary in their severity with one third of the cases resulting in death.

Equivalent ICD-9 Code GENERAL EQUIVALENCE MAPPINGS (GEM)

Cerebral artery occlusion, unspecified with cerebral infarction (approximate match)

This is the official approximate match mapping between ICD9 and ICD10, as provided by the General Equivalency mapping crosswalk. This means that while there is no exact mapping between this ICD10 code I63.9 and a single ICD9 code, 434.91 is an approximate match for comparison and conversion purposes.
