ICD-10 Code C83.87 – Other non-follicular lymphoma, spleen (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code C83.87 – Other non-follicular lymphoma, spleen
What it is
C83.87 identifies a non-follicular lymphoma involving the spleen. Use it when the record specifies lymphoma of the spleen and the type is not otherwise classified as follicular.
Clinical signs
Clinical features vary; refer to documentation. Commonly, splenic lymphoma may be associated with splenomegaly, abdominal fullness, or findings on imaging or pathology confirming splenic involvement.
When to use this code
Use C83.87 when the provider documents other non-follicular lymphoma with primary or specific splenic involvement. It is appropriate when the diagnosis clearly identifies the spleen as the site and does not name a more specific lymphoma subtype.
If the chart only says lymphoma with generalized disease or another organ site, check documentation before coding this diagnosis. Code the documented histology and site as recorded.
Do not use for
Do not use this code for follicular lymphoma, unspecified lymphoma, or lymphoma without splenic involvement. Check documentation if the spleen is enlarged but lymphoma is not confirmed.
Coding tip
Verify both the lymphoma type and the anatomic site; the spleen must be specifically documented to support C83.87.
