Hemangioma of other sites

This code signifies a benign vascular tumor characterized by an abnormal proliferation of blood vessels, occurring in anatomical locations other than those specifically classified elsewhere (e.g., skin, intraocular, intracranial, or gastrointestinal). These lesions are typically congenital or appear shortly after birth, growing rapidly before often involuting spontaneously.

Apply this code when documentation specifies a hemangioma located in an unspecified or less common site, such as muscle, bone, or internal organs not covered by more specific D18.0x codes. Supporting documentation should clearly identify the diagnosis as a hemangioma and specify its anatomical location, confirming it's not a lymphatic malformation or other vascular anomaly.

• Ensure the documentation explicitly states "hemangioma" and not another vascular malformation (e.g., lymphangioma, arteriovenous malformation), as these have different codes.
• Always review the medical record for a more specific D18.0x code if the site is clearly defined (e.g., D18.01 for skin, D18.02 for intracranial).
• This code is for benign neoplasms; if the lesion is malignant, a code from the C49 category (Malignant neoplasm of other connective and soft tissue) or other appropriate malignant neoplasm code should be used.
