Classification of Nontraumatic Intracerebral Hemorrhage (I61)
Category I61, Nontraumatic intracerebral hemorrhage, also classifies the specific site of the intracerebral hemorrhage.
There are nine codes within this category with the fourth character classifying the site of the hemorrhage:
I61.0 ______ I61.1 ______ I61.2 ______ I61.3 _____ I61.4 ______ I61.5 ______ I61.6 _____ I61.8 ______ I61.9 _____
a. Nontraumatic intracerebral hemorrhage, intraventricular
b. Nontraumatic intracerebral hemorrhage in the brain stem
c. Other nontraumatic intracerebral hemorrhages.
d. Nontraumatic intracerebral hemorrhage in hemisphere, unspecified
e. Nontraumatic intracerebral hemorrhage, unspecified
f. Nontraumatic intracerebral hemorrhage in hemisphere, subcortical
g. Nontraumatic intracerebral hemorrhage, multiple localized
h. Nontraumatic intracerebral hemorrhage in hemisphere, cortical
i. Nontraumatic intracerebral hemorrhage in the cerebellum
Anatomy Note: The brain consists of three main structures: cerebrum, cerebellum and brain stem. The cerebrum is divided into two hemispheres (right and left) with each hemisphere consisting of four lobes (frontal, parietal, occipital and temporal) The outer portion of the cerebrum is the cerebral cortical area (gray matter) and the subcortical area is the internal structure located under or below the cerebral cortex.
