ICD-10 Code D18.0 – Hemangioma (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code D18.0 – Hemangioma
What it is
D18.0 identifies a hemangioma, a benign vascular tumor made up of abnormal blood vessels. Use it when the record documents a hemangioma and no more specific vascular lesion code applies.
Clinical signs
These lesions are often visible as a red, blue, or purple skin or soft-tissue mass. Clinical features vary; refer to documentation for site, size, and whether the lesion is congenital or acquired.
When to use this code
Use D18.0 when the provider documents hemangioma without a more specific anatomic or histologic description. It may appear in records for evaluation, observation, imaging follow-up, or excision of a confirmed hemangioma. Code the documented location if the chart supports it.
Do not use for
Do not use this code for other vascular malformations, lymphangiomas, or unspecified benign neoplasms. If the documentation is unclear, check documentation rather than assuming hemangioma.
Coding tip
Match the code to the provider’s exact wording and any documented site, because more specific vascular lesion codes may apply.
