ICD-10 Code C83.88 – Other non-follicular lymphoma, lymph nodes of multiple sites (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code C83.88 – Other non-follicular lymphoma, lymph nodes of multiple sites
What it is
This code identifies a non-follicular lymphoma involving lymph nodes at more than one site. Use it when the record specifies this lymphoma type but does not name a more exact subtype.
Clinical signs
Clinical features vary; refer to documentation. Common lymphoma findings may include enlarged lymph nodes, constitutional “B” symptoms, or other signs of nodal disease, but the exact pattern depends on the confirmed diagnosis.
When to use this code
Use C83.88 when the provider documents other non-follicular lymphoma and states that multiple lymph node sites are involved. It is appropriate when the chart supports nodal involvement at several locations and a more specific lymphoma code is not available.
If the pathology or oncology note names a more specific non-follicular lymphoma subtype, code that diagnosis instead. Check documentation when the site is unclear or when only one nodal region is confirmed.
Do not use for
Do not use this code for follicular lymphoma, Hodgkin lymphoma, or lymphoma limited to a single lymph node site. Check documentation if the record describes extranodal disease or a different subtype.
Coding tip
Verify both the lymphoma subtype and the number of involved nodal sites before assigning C83.88.
