ICD-10 Code D18.02 – Hemangioma of intracranial structures (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code D18.02 – Hemangioma of intracranial structures
What it is
D18.02 identifies a benign vascular lesion made of blood vessels located within the skull or brain. Use it when documentation specifically states a hemangioma of intracranial structures.
Clinical signs
Clinical features vary; refer to documentation. Intracranial vascular lesions may be found on imaging or during evaluation for neurologic symptoms, but the record should clearly identify a hemangioma.
When to use this code
Use D18.02 when the provider documents a hemangioma involving intracranial structures, such as the brain or other structures inside the skull. It is appropriate when imaging, pathology, or specialist notes confirm the diagnosis. If the site is unclear, check documentation before coding.
Do not use for
Do not use this code for nonspecific intracranial masses, aneurysms, or other vascular malformations unless a hemangioma is documented. Check documentation if the lesion is described only as a vascular abnormality.
Coding tip
Code the exact intracranial site only when the record supports it; otherwise, query for clarification.
