ICD-10 Code C81.96 – Hodgkin lymphoma, unspecified, intrapelvic lymph nodes (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code C81.96 – Hodgkin lymphoma, unspecified, intrapelvic lymph nodes
What it is
C81.96 identifies Hodgkin lymphoma when the record specifies intrapelvic lymph node involvement but does not name a subtype. Use it for a malignant lymphoid cancer affecting pelvic nodes.
Clinical signs
Clinical features vary; refer to documentation. Commonly documented findings include enlarged pelvic lymph nodes on imaging or pathology, and lymphoma-related symptoms such as unexplained weight loss, fever, or night sweats.
When to use this code
Use this code when the provider documents Hodgkin lymphoma involving intrapelvic lymph nodes and does not specify a histologic subtype. It also fits cases where the diagnosis is confirmed, but the pelvic nodal site is the only location documented. If laterality or a more specific subtype is recorded, code the more specific option instead.
Do not use for
Do not use this code for non-Hodgkin lymphoma, other lymph node regions, or Hodgkin lymphoma with a specified subtype that has its own code. Check documentation if the site is unclear.
Coding tip
Confirm both the Hodgkin lymphoma diagnosis and the intrapelvic node site in the provider note before assigning C81.96.
