Short answer · Medically reviewed summary · Last updated: 2026-05-08
Lymphangiomatosis does not have a unique, dedicated ICD-10 or ICD-9 code; instead, it is typically classified under broader categories for lymphatic vessel disorders. Clinicians generally use ICD-10 code Q82.8 (Other specified congenital malformations of the skin) or I89.8 (Other specified noninfectious disorders of lymphatic vessels) to document Lymphangiomatosis in medical records. How is Lymphangiomatosis classified in medical coding? Because Lymphangiomatosis is a rare, systemic condition characterized by the widespread proliferation of lymphatic vessels, it lacks a specific, singular ICD-10 code.

How is Lymphangiomatosis classified in medical coding?
Because Lymphangiomatosis is a rare, systemic condition characterized by the widespread proliferation of lymphatic vessels, it lacks a specific, singular ICD-10 code. In the older ICD-9 system, it was often coded under 759.89 (Other specified congenital anomalies) or 457.8 (Other noninfectious disorders of lymphatic vessels). Healthcare providers must often use secondary codes to specify the organs affected, such as the lungs, bones, or spleen, to ensure accurate billing and clinical tracking for patients with Lymphangiomatosis.
What are the primary clinical features of Lymphangiomatosis?
Lymphangiomatosis is a complex disorder where abnormal lymphatic channels infiltrate multiple tissues and organs. While the clinical presentation varies significantly between patients, common manifestations include:
- Chylous effusions (fluid accumulation in the chest or abdomen).
- Lytic bone lesions, which may lead to pathological fractures.
- Splenic or hepatic involvement causing organ enlargement.
- Respiratory distress due to pulmonary lymphatic infiltration.
How is a diagnosis of Lymphangiomatosis confirmed?
Diagnosing Lymphangiomatosis is challenging due to its rarity and systemic nature. It typically requires a multidisciplinary approach involving radiology and pathology. Imaging studies, such as MRI or CT scans, are essential to visualize the extent of lymphatic involvement. A definitive diagnosis of Lymphangiomatosis often requires a tissue biopsy to confirm the presence of benign, proliferating lymphatic channels.
Next steps
- Consult with a specialist in lymphatic anomalies or a thoracic surgeon experienced in rare vascular disorders.
- Connect with the Lymphangiomatosis community at DiseaseMaps.org to share experiences with others navigating this condition.
- Request a referral to a center of excellence that specializes in complex lymphatic malformations.
- Maintain a detailed copy of your medical records and imaging, as these are vital when seeking second opinions.
