ICD10 code of Lymphatic Malformations and ICD9 code

Lymphatic malformations are classified under ICD-10 code Q82.8 (Other specified congenital malformations of the skin), while the legacy ICD-9 code most frequently utilized is 757.39 (Other specified congenital malformations of skin). These codes are essential for medical billing and tracking the clinical management of lymphatic malformations within healthcare systems.

What are lymphatic malformations?

Lymphatic malformations are rare, benign, fluid-filled channels or spaces that result from abnormal development of the lymphatic system. While they are present at birth, they may not become clinically apparent until later in childhood or adulthood. At DiseaseMaps.org, 11 community members have shared their experiences with lymphatic malformations, highlighting the diverse ways these lesions can present, ranging from small superficial vesicles to large, deep-seated masses that may involve muscle or bone.

How are lymphatic malformations classified for medical coding?

Accurate coding is vital for coordinating multidisciplinary care for those living with lymphatic malformations. Because these lesions are congenital vascular anomalies, they are often categorized under the broader umbrella of vascular anomalies. Key coding considerations include:

• ICD-10 Q82.8: The primary code for lymphatic malformations involving the skin.


• ICD-9 757.39: The historical primary code used for these specific congenital anomalies.


• Site-specific coding: Clinicians often append additional codes to specify the anatomical location (e.g., cervicofacial, thoracic, or abdominal) to better define the impact of the lymphatic malformations.


• Clinical documentation: Physicians should document the type (macro-cystic, micro-cystic, or combined) to assist with insurance authorization and treatment planning.

Why is early diagnosis of lymphatic malformations important?

Early diagnosis of lymphatic malformations allows for the monitoring of potential complications, such as infection, hemorrhage, or airway obstruction if the lesions are located in the head and neck. Because lymphatic malformations can be locally aggressive, specialized care from interventional radiologists, plastic surgeons, or pediatric surgeons is often required to manage the condition effectively.

Next steps

• Consult with a vascular anomaly specialist or an interventional radiologist to develop a personalized management plan.


• Join the community at DiseaseMaps.org to connect with others sharing experiences with lymphatic malformations.


• Maintain a detailed log of any changes in size or symptoms to share with your care team during follow-up visits.
