ICD-10 Code C83.8 – Other non-follicular lymphoma (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code C83.8 – Other non-follicular lymphoma
What it is
C83.8 identifies a non-follicular lymphoma that does not fit a more specific subtype. Use it when the record confirms lymphoma but the exact non-follicular histology is not named.
Clinical signs
Findings depend on the lymphoma subtype, but documentation often notes lymphadenopathy, B symptoms, or extranodal involvement. Clinical features vary; refer to documentation.
When to use this code
Use C83.8 when pathology, oncology, or discharge documentation states “other non-follicular lymphoma” or gives a non-follicular lymphoma diagnosis that is not indexed to a more specific code. It also fits when the subtype is confirmed as non-follicular but the exact category is not available in the chart. Check documentation if the report names a specific lymphoma subtype.
Do not use for
Do not use this code for follicular lymphoma or when the record supports a more specific non-follicular lymphoma code. If the diagnosis is uncertain or only “lymphoma” is documented, check documentation.
Coding tip
Code the most specific lymphoma type documented; default to C83.8 only when the record clearly supports a non-follicular lymphoma but not a narrower code.
