Cerebral cysts

This code signifies the presence of abnormal, fluid-filled sacs within the brain tissue. These cysts can be congenital or acquired and may or may not cause neurological symptoms depending on their size and location.

Assign this code for documented cerebral cysts, such as arachnoid cysts, porencephalic cysts, or other non-neoplastic intracranial cysts. Documentation should clearly identify the lesion as a cyst within the cerebrum, often confirmed by imaging studies like MRI or CT scans.

• Differentiate from neoplastic lesions (e.g., brain tumors), which have distinct coding.
• If the cyst is causing specific neurological symptoms, code those symptoms additionally.
• Do not use for cysts of the pituitary gland or other non-cerebral intracranial locations.
