Other noninfective disorders of lymphatic vessels and lymph nodes (I89) ICD-10-CM
The I89 code range covers other noninfective disorders of lymphatic vessels and lymph nodes with 5 ICD-10-CM diagnosis codes. 4 of them are billable and valid for claim submission in fiscal year 2026, and the category headers group them but cannot themselves be billed.
Type 1 Excludes
A type 1 excludes note is a pure excludes note. It means "NOT CODED HERE!" An Excludes1 note indicates that the code excluded should never be used at the same time as the code above the Excludes1 note. An Excludes1 is used when two conditions cannot occur together, such as a congenital form versus an acquired form of the same condition.

Clinical Terms in This Code Range
Definitions from the National Library of Medicine for conditions coded in the I89 range.
Breast Cancer Lymphedema
Abnormal accumulation of lymph in the arm, shoulder and breast area associated with surgical treatment (e.g., MASTECTOMY) or radiation treatment of breast cancer.
Chylous Ascites
Presence of milky lymph (CHYLE) in the PERITONEAL CAVITY, with or without infection.
Lipedema
Disorder of adipose tissue characterized by symmetric and bilateral enlargement of the lower extremities due to abnormal deposition of SUBCUTANEOUS FAT often in obese women. It is associated with HEMATOMA, pain and may progress to secondary LYMPHEDEMA which is known as lipolymphedema.
Lymphangitis
A lymphatic disease characterized by INFLAMMATION of LYMPHATIC VESSELS.
Lymphedema
Edema due to obstruction of lymph vessels or disorders of the lymph nodes.
Lymphocele
Cystic mass containing lymph from diseased lymphatic channels or following surgical trauma or other injury.
Mastectomy
Surgical procedure to remove one or both breasts.
Mesenteric Cyst
A rare intra-abdominal tumor in the MESENTERY. Mesenteric cysts are usually benign and can be very large fluid-filled (2000 mL) lesions.
Non-Filarial Lymphedema
A form of elephantiasis caused by soil particles which penetrate the skin of the foot. It is limited to tropical regions with soils of high volcanic content.
Yellow Nail Syndrome
A rare condition characterized by the presence of yellow nails, LYMPHEDEMA, and/or PLEURAL EFFUSION with respiratory tract involvement. Abnormal lymphatic network may play a role in its etiology. Occasionally inherited, yellow nail syndrome mostly is sporadic without apparent family history.
About the I89 Code Range
The ICD-10 code I89 and its subcategories classify other noninfective disorders specifically affecting the lymphatic vessels and lymph nodes. These codes are essential for identifying conditions related to lymphatic system dysfunctions that are not caused by infections.
This section includes codes such as I89.0, used for various forms of lymphedema, a swelling caused by lymph fluid buildup, which covers conditions commonly referred to as lipo-lymphedema, primary lymphedema, and secondary causes such as postsurgical or radiation-induced lymphedema. The code I89.1 covers lymphangitis, an inflammation of lymphatic vessels often associated with localized skin infections and conditions like ascending lymphangitis. The category I89.8 captures other specified noninfective lymphatic disorders, including lymphoceles (postprocedural lymph fluid collections), chylous cysts, lymph node infarctions, and fistulas. Finally, I89.9 is for unspecified noninfective lymphatic disorders, used when specific diagnosis details are lacking. Understanding the ICD-10 code for these lymphatic conditions helps medical professionals accurately document and manage a variety of lymphatic vessel and lymph node pathologies documented under terms like chronic lymphatic disease, lymphostasis, and lymphatic vessel disorders.
