Hemangioma unspecified site

This code represents a benign vascular tumor characterized by an abnormal proliferation of blood vessels. Hemangiomas are typically present at birth or appear shortly thereafter, often growing rapidly before regressing spontaneously. They can occur on or within any organ system.

Use this code when the medical record documents a hemangioma without specifying its anatomical location. This is appropriate for initial diagnoses where the exact site is not yet determined or when the physician explicitly states "unspecified site." Documentation should clearly indicate the presence of a hemangioma.

• Avoid using this code if a more specific anatomical site (e.g., skin, liver, brain) is documented; look for D18.01-D18.09.
• Do not confuse hemangiomas with vascular malformations, which are distinct entities and coded differently.
• If the hemangioma is complicated by hemorrhage or ulceration, additional codes may be necessary to capture these secondary conditions.
