Compression of brain

This code represents a non-traumatic compression of the brain, indicating pressure on brain tissue from various internal causes. This pressure can lead to neurological dysfunction due to impaired blood flow or direct tissue damage. It describes a condition where the brain is being squeezed or pressed upon by something other than an external injury.

Use this code for conditions such as brain herniation due to tumor, hydrocephalus, or cerebral edema not caused by trauma. Documentation should clearly state "compression of brain" and specify a non-traumatic etiology, such as a mass effect from a neoplasm or increased intracranial pressure from a non-injurious event.

• Always confirm the etiology is non-traumatic; if traumatic, refer to the S06.A- series.
• Code the underlying cause of the compression (e.g., brain tumor, hydrocephalus) first, followed by this code as a manifestation.
• Ensure documentation differentiates between generalized cerebral edema and specific brain compression.
