2025 ICD-10-CM code I89
Other noninfective disorders of lymphatic vessels and lymph nodes.
Medical necessity for services related to I89 is determined by the specific condition being treated. For example, lymphedema treatment might be deemed medically necessary if it significantly impacts the patient's function or quality of life. Documentation should clearly establish the severity of the condition and the rationale for the chosen treatment.
Diagnosis and management of non-infectious lymphatic disorders falls under various specialties depending on the specific condition and its etiology. This may include vascular surgeons, interventional radiologists, lymphologists (if available), dermatologists, oncologists, and primary care physicians.
- Diseases of the circulatory system (I00-I99)
- Diseases of veins, lymphatic vessels and lymph nodes, not elsewhere classified (I80-I89)
In simple words: This code covers other conditions affecting the lymph vessels and nodes that are not caused by infection, such as lymphedema (swelling due to lymph fluid buildup) or other non-infectious lymphatic disorders.
Other noninfective disorders of lymphatic vessels and lymph nodes. Excludes1: chylocele, tunica vaginalis (nonfilarial) NOS (N50.89), enlarged lymph nodes NOS (R59.-), filarial chylocele (B74.-) hereditary lymphedema (Q82.0)
Example 1: A patient presents with chronic swelling in their left leg, diagnosed as lymphedema secondary to previous cancer treatment.The appropriate code is I89, potentially with a more specific 5th character if applicable (e.g., I89.0 for lymphedema, unspecified)., A patient is found to have lymphangiectasia, a condition characterized by dilated lymphatic vessels. In the absence of a more specific code, I89 would be used., A patient experiences persistent swelling in the arm following a mastectomy and lymph node removal. After ruling out infection and other causes, the swelling is determined to be lymphedema. I89 is the appropriate code to represent this non-infectious lymphatic disorder.
Thorough documentation should include the type and location of the lymphatic disorder, the stage (if applicable, such as in lymphedema), the underlying cause (if known), associated symptoms, and any treatments provided.
** For accurate coding, always refer to the current ICD-10-CM coding guidelines and seek expert advice when necessary. iFrameAI is useful tool for the accurate clinical coding and billing.
