ICD-10 Code C85.96 – Non-Hodgkin lymphoma, unspecified, intrapelvic lymph nodes (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code C85.96 – Non-Hodgkin lymphoma, unspecified, intrapelvic lymph nodes
What it is
C85.96 identifies non-Hodgkin lymphoma when the site is the intrapelvic lymph nodes and the specific lymphoma type is not further specified. Use it for malignant lymphoid disease documented in pelvic nodes without a more precise code.
Clinical signs
Clinical features vary; refer to documentation. Common findings may include enlarged pelvic lymph nodes on imaging, but diagnosis usually depends on pathology or oncology documentation rather than symptoms alone.
When to use this code
Use this code when the record clearly states non-Hodgkin lymphoma involving intrapelvic lymph nodes and does not identify a more specific subtype. It also fits when the provider documents lymphoma in pelvic nodes but the exact histology is unspecified. Check documentation if the site is reported differently or if another lymphoma code is more specific.
Do not use for
Do not use it for Hodgkin lymphoma, lymphoma in nonpelvic nodes, or a fully specified non-Hodgkin subtype with a more exact code. Do not assign it when the documentation only says lymphadenopathy without confirmed lymphoma.
Coding tip
Confirm both the lymphoma type and the anatomic site; if either is missing, query the provider before coding.
