Additional Info

• This code is for cerebral ischemia/stroke due to thrombosis of a cerebral artery (not embolic).

Includes

• Lacunar infarcts on old imaging or documentation

• If the ischemic stroke due to thrombosis spontaneously "transforms" and bleeds, then COMBINE it with the appropriate code for the hemorrhage (see below).
• If the hemorrhage after an ischemic stroke was NOT spontaneous, but followed anticoagulation, then the hemorrhage should be coded as Hemorrhage, due to anticoagulant or thrombolytic drug as a complication of treatment Iatrogenic, complication of medical or surgical care NOS not a complication of the stroke per se.

Excludes

• If the ischemic stroke is embolic (including cardioembolic), use Cerebral infarction/stroke due to embolism.
• If a stroke is not specified as hemorrhagic, embolic or ishemic, use Stroke, NOS.

Comorbid Rule exception

Regular comorbid rules exception: Strokes (of any sort, ischemic or hemorrhagic) -- code even resolved strokes with no current sequelae as comorbid diagnoses. If a patient has a past history of stroke, use the regular stroke codes to identify this, even if the patient does not have any residual deficits we will now capture ANY past history of stroke. This is contrary to the usual rules about Comorbid_Diagnosis#When_not_to_code_a_dx_at_all.

Alternate ICD10s to consider coding instead or in addition

• Stroke, NOS
• Hemorrhage, subarachnoid or ruptured cerebral aneurysm
• Hemorrhage, intracerebral/intracranial, nontraumatic (ICH, hemorrhagic stroke)
• Subdural or epidural hematoma/hemorrhage, nontraumatic
