ICD-10 Code I63.19 – Cerebral infarction due to embolism of other precerebral artery (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code I63.19 – Cerebral infarction due to embolism of other precerebral artery
What it is
This code identifies an ischemic stroke caused by an embolus blocking a precerebral artery other than the carotid or vertebral arteries. Use it when documentation specifies cerebral infarction due to embolism in another named precerebral vessel.
Clinical signs
Typical findings are sudden focal neurologic deficits consistent with acute cerebral ischemia, such as weakness, speech difficulty, facial droop, or visual changes. Clinical features vary; refer to documentation and imaging support when available.
When to use this code
Use I63.19 when the provider documents a cerebral infarction from embolism in an other precerebral artery and does not name the vessel as carotid or vertebral. Apply it for confirmed ischemic stroke cases with an embolic cause tied to that vessel.
If the record only says stroke, cerebral infarction, or embolism without vessel detail, check documentation before assigning this code. You should code the most specific documented cause and artery site available.
Do not use for
Do not use this code for hemorrhagic stroke, transient ischemic attack, or infarction from thrombosis or unspecified occlusion. Do not use it when the affected artery is documented as carotid or vertebral.
Coding tip
Look for both the infarction and the embolic precerebral artery source in the provider note before coding I63.19.
