ICD-10 Code C85.97 – Non-Hodgkin lymphoma, unspecified, spleen (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code C85.97 – Non-Hodgkin lymphoma, unspecified, spleen
What it is
C85.97 identifies non-Hodgkin lymphoma involving the spleen when the specific lymphoma type is not documented. Use it when the record confirms splenic involvement but does not name a more specific subtype.
Clinical signs
Clinical features vary; refer to documentation. Commonly noted findings may include splenomegaly, abdominal fullness, or incidental imaging evidence of splenic lymphoma, but the diagnosis should be supported by pathology or specialist assessment.
When to use this code
Use this code when the provider documents non-Hodgkin lymphoma in the spleen and does not specify a histologic subtype. It also fits cases where the spleen is the documented site of involvement and the chart remains nonspecific. If another site is clearly the primary focus, check documentation before assigning this code.
Do not use for
Do not use it for Hodgkin lymphoma, other specified non-Hodgkin lymphoma subtypes, or lymphoma documented only as generalized without splenic involvement. If the record is unclear about site or type, check documentation.
Coding tip
Assign C85.97 only when both non-Hodgkin lymphoma and spleen involvement are documented, and no more specific lymphoma code is available.
