ICD-10 Code C82.8 – Other types of follicular lymphoma (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code C82.8 – Other types of follicular lymphoma
What it is
C82.8 identifies follicular lymphoma that does not fit the more specific follicular lymphoma categories in ICD-10-CM. Use it when the record clearly states another follicular lymphoma type, but not a subclassified one.
Clinical signs
Clinical features vary; refer to documentation. Follicular lymphoma often presents as painless enlarged lymph nodes and may be found on biopsy with an indolent course.
When to use this code
Use C82.8 when the provider documents follicular lymphoma and specifies a type that is not separately indexed or described elsewhere in the follicular lymphoma category. It is also appropriate when pathology confirms follicular lymphoma but the subtype is recorded only as “other.”
Check the full report if the note includes grade, site, or transformation details, because those elements may require a different code. Do not assume C82.8 if the documentation names a more specific follicular lymphoma code.
Do not use for
Do not use this code for diffuse non-follicular lymphoma, unspecified lymphoma, or a separately coded follicular lymphoma subtype. Check documentation when the diagnosis is incomplete or unclear.
Coding tip
Code from the exact lymphoma wording in the pathology or oncology note, and query the provider if “other” follicular lymphoma is not clearly supported.
