ICD-10 Code D18.09 – Hemangioma of other sites (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code D18.09 – Hemangioma of other sites
What it is
D18.09 identifies a hemangioma located in a site not named by a more specific ICD-10-CM code. Use it for a benign vascular tumor when the record documents an “other site” location.
Clinical signs
Clinical features vary; refer to documentation. Hemangiomas are often described as a localized vascular mass, skin lesion, or soft-tissue growth, sometimes noted on imaging or physical exam.
When to use this code
Use D18.09 when the clinician documents hemangioma and the anatomic site does not match a more specific hemangioma code. It also fits when the note states “other site” or gives a location not separately indexed. Check documentation if the lesion type or site is unclear.
Do not use for
Do not use this code for hemangiomas with a more specific site code, or when the lesion is documented as another vascular or nonvascular tumor. If the diagnosis is uncertain, check documentation.
Coding tip
Confirm the exact site in the record before assigning D18.09, because a more specific code may apply.
