ICD-10 Code C85.86 – Other specified types of non-Hodgkin lymphoma, intrapelvic lymph nodes (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code C85.86 – Other specified types of non-Hodgkin lymphoma, intrapelvic lymph nodes
What it is
This code identifies a non-Hodgkin lymphoma involving intrapelvic lymph nodes when the specific subtype is documented as other specified. It applies to malignant lymphoid disease located in pelvic nodal tissue.
Clinical signs
Clinical features vary; refer to documentation. Patients may have pelvic lymph node enlargement, pain, or mass effect, but the record should confirm lymphoma and the intrapelvic nodal site.
When to use this code
Use this code when the provider documents other specified non-Hodgkin lymphoma affecting intrapelvic lymph nodes and no more specific lymphoma type is named. It is appropriate for pathology, oncology, or imaging documentation that clearly localizes disease to pelvic nodes. Check documentation if the site or subtype is unclear.
Do not use for
Do not use it for unspecified non-Hodgkin lymphoma, other lymph node regions, or Hodgkin lymphoma. If the record names a different anatomic site or a more specific lymphoma subtype, code that instead.
Coding tip
Confirm both the lymphoma subtype and the intrapelvic nodal location before assigning C85.86.
