Cerebral infarction due to thrombosis of left cereblr artery

This diagnosis code signifies a stroke resulting from a blockage (thrombosis) within an artery supplying the left cerebellum. This interruption of blood flow leads to tissue death (infarction) in the left cerebellar region of the brain. Patients typically present with symptoms such as ataxia, nystagmus, and vertigo localized to the left side.

Use this code when documentation clearly indicates an acute or subacute cerebral infarction specifically attributed to a thrombotic occlusion of an artery supplying the left cerebellum. This diagnosis requires physician documentation specifying both the etiology (thrombosis) and the precise anatomical location (left cerebellar artery).

• Ensure documentation differentiates between embolism and thrombosis as the cause of infarction.
• Verify the laterality (left) of the cerebellar artery involvement.
• Do not use this code for transient ischemic attacks (TIAs) or for infarctions due to hemorrhage.
