ICD-10 Code C82.87 – Other types of follicular lymphoma, spleen (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code C82.87 – Other types of follicular lymphoma, spleen
What it is
This code identifies follicular lymphoma involving the spleen when the subtype is not otherwise specified by another more exact follicular lymphoma code. It tells you the malignancy is documented as affecting splenic tissue.
Clinical signs
Clinical features vary; refer to documentation. Common findings may include splenomegaly, abdominal fullness, or incidental imaging evidence of splenic involvement in a known follicular lymphoma.
When to use this code
Use this code when the record clearly documents follicular lymphoma of the spleen and no more specific follicular lymphoma code applies. It is appropriate for confirmed splenic involvement in the absence of a different site-specific or histologic detail. Check documentation if the spleen is mentioned only as part of disseminated disease.
Do not use for
Do not use it for nonspecific lymphoma, reactive splenomegaly, or splenic masses without documented follicular lymphoma. If the chart does not confirm splenic involvement, check documentation.
Coding tip
Verify both the lymphoma type and the spleen as the documented site before assigning C82.87.
