ICD-10 Code C82.97 – Follicular lymphoma, unspecified, spleen (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code C82.97 – Follicular lymphoma, unspecified, spleen
What it is
C82.97 identifies follicular lymphoma involving the spleen, without a more specific subtype. Use it when documentation names splenic follicular lymphoma but does not specify grade or other details.
Clinical signs
Clinical features vary; refer to documentation. Commonly, records may note splenic enlargement, incidental imaging findings, or lymphoma confirmed by pathology, biopsy, or oncology assessment.
When to use this code
Use this code when the provider documents follicular lymphoma of the spleen and no further histologic detail is available. It also fits cases where the spleen is the documented involved site in a confirmed follicular lymphoma diagnosis. Check documentation if the record describes multiple sites or a different lymphoma type.
Do not use for
Do not use it for follicular lymphoma with a specified grade or for lymphoma involving other organs only. If the spleen is not clearly documented as involved, check documentation.
Coding tip
Match the code to the exact lymphoma type and site documented; unspecified codes should be used only when the record lacks greater detail.
