ICD-10 Code G93.0 – Cerebral cysts (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code G93.0 – Cerebral cysts
What it is
Cerebral cysts are fluid-filled sacs or cavities within the brain. This code identifies a documented intracranial cystic lesion when the record uses that term.
Clinical signs
Clinical features vary; refer to documentation. Patients may be asymptomatic or have neurologic findings related to location, size, or mass effect.
When to use this code
Use G93.0 when the provider documents a cerebral or intracranial cyst and does not specify a more exact diagnosis. It may apply when imaging confirms a cystic brain lesion and the note supports coding it as a cerebral cyst. If the record names a different specific cyst type, code that diagnosis instead.
Do not use for
Do not use this code for cysts in other organs or for nonspecific abnormal imaging without a documented cerebral cyst. Check documentation if the lesion is better classified elsewhere.
Coding tip
Code only what the provider documents; if the report gives a specific cyst name, use that more precise code.
