ICD-10 Code C82.88 – Other types of follicular lymphoma, lymph nodes of multiple sites (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code C82.88 – Other types of follicular lymphoma, lymph nodes of multiple sites
What it is
C82.88 identifies follicular lymphoma involving lymph nodes at multiple sites when the subtype is documented as other than the more specific listed categories. Use it for a confirmed diagnosis, not for suspected lymphoma.
Clinical signs
Clinical features vary; refer to documentation. Common findings may include painless enlarged lymph nodes, fatigue, or incidental detection on imaging or biopsy, with pathology confirming follicular lymphoma.
When to use this code
Use this code when the record states other types of follicular lymphoma and clearly documents lymph node involvement at multiple sites. It is appropriate after pathology, oncology, or discharge documentation confirms the diagnosis. Check documentation if the site is not clearly multiple or the subtype is unspecified.
Do not use for
Do not use C82.88 for follicular lymphoma limited to one lymph node region or for a different lymphoma subtype. Do not use it when the diagnosis is only suspected or pending confirmation.
Coding tip
Verify both the lymphoma subtype and the multiple-site nodal involvement before assigning C82.88.
