ICD-10 Code I89.8 – Other specified noninfective disorders of lymphatic vessels and lymph nodes (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code I89.8 – Other specified noninfective disorders of lymphatic vessels and lymph nodes
What it is
I89.8 identifies a noninfective disorder of the lymphatic vessels or lymph nodes that does not fit a more specific ICD-10 category. Use it when the chart describes an unusual lymphatic problem without infection.
Clinical signs
Clinical features vary; refer to documentation. Findings may include lymphatic swelling, node enlargement, or impaired lymph drainage, but the exact picture depends on the documented condition.
When to use this code
Use I89.8 when the provider documents a specified lymphatic disorder and states it is noninfective, but no more precise code is available. It also fits when the record describes an atypical lymphatic abnormality that is clearly separate from infection or malignancy. Check documentation for the exact diagnosis.
Do not use for
Do not use this code for infectious lymphadenitis, malignant lymph node disease, or lymphedema that has a more specific code. If the condition is better described elsewhere, choose that code instead.
Coding tip
Look for the provider’s exact wording and confirm the disorder is noninfective before assigning I89.8.
