ICD-10 code for thrombotic paralysis

The ICD-10-CM code for thrombotic paralysis is I63.3 (Cerebral infarction due to thrombosis of cerebral arteries).

Within I63 (cerebral infarction), I63.3 is specifically for cerebral infarction due to thrombosis of cerebral arteries. Related codes cover due to thrombosis of precerebral arteries (I63.0), due to embolism of precerebral arteries (I63.1), due to unspecified occlusion or stenosis of precerebral arteries (I63.2), due to embolism of cerebral arteries (I63.4), due to unspecified occlusion or stenosis of cerebral arteries (I63.5), due to cerebral venous thrombosis, nonpyogenic (I63.6), other cerebral infarction (I63.8) and unspecified (I63.9).

To report this condition, pick the subcode that matches the documentation: I63.30 (artery), I63.31 (artery), I63.32 (artery), I63.33 (artery), I63.34 (artery) and I63.39 (artery).

Use an additional code, if applicable, to identify status post administration of tPA (rtPA) in a different facility within the last 24 hours prior to admission to current facility (Z92.82). Use an additional code, if known, to indicate National Institutes of Health Stroke Scale (NIHSS) score (R29.7-).
