Rupture of blood vessel in brain
432: Other and unspecified intracranial hemorrhage
433: Occlusion and stenosis of precerebral arteries
The following fifth-digit subclassification is for use with category 433:
0 without mention of cerebral infarction
1 with cerebral infarction
Includes:
embolism of basilar, carotid, and vertebral arteries
narrowing of basilar, carotid, and vertebral arteries
obstruction of basilar, carotid, and vertebral arteries

to current facility (V45.88)
Excludes:
insufficiency NOS of precerebral arteries (435.0-435.9)
434: Occlusion of cerebral arteries
The following fifth-digit subclassification is for use with category 434:
0 without mention of cerebral infarction
1 with cerebral infarction
Use 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 (V45.88)
435: Transient cerebral ischemia
Includes:
cerebrovascular insufficiency (acute) with transient focal neurological signs and symptoms
insufficiency of basilar, carotid, and vertebral arteries
spasm of cerebral arteries
Excludes:
acute cerebrovascular insufficiency NOS (437.1)
that due to any condition classifiable to 433 (433.0-433.9)
436: Acute, but ill-defined, cerebrovascular disease

thrombotic (434.01)
437: Other and ill-defined cerebrovascular disease
438: Late effects of cerebrovascular disease
Note:
This category is to be used to indicate conditions in 430-437 as the cause of late effects. The "late effects" include conditions specified as such, or as sequelae, which may occur at any time after the onset of the causal condition.
Excludes:
personal history of:
cerebral infarction without residual deficits (V12.54)
PRIND (Prolonged reversible ischemic neurologic deficit) (V12.54)
RIND (Reversible ischemic neurological deficit) (V12.54)
transient ischemic attack (TIA) (V12.54)
