ICD-10 Code C81.33 – Lymphocyte depleted Hodgkin lymphoma, intra-abdominal lymph nodes (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code C81.33 – Lymphocyte depleted Hodgkin lymphoma, intra-abdominal lymph nodes
What it is
C81.33 identifies lymphocyte-depleted Hodgkin lymphoma involving the intra-abdominal lymph nodes. Use it when the record specifies this Hodgkin lymphoma subtype and nodal site.
Clinical signs
Clinical features vary; refer to documentation. Commonly, Hodgkin lymphoma presents with enlarged lymph nodes, constitutional symptoms, or imaging and biopsy findings confirming the subtype.
When to use this code
Use this code when the provider documents lymphocyte-depleted Hodgkin lymphoma and names intra-abdominal lymph node involvement. It may appear on pathology, oncology, or discharge records. If the subtype or nodal site is unclear, check documentation before coding.
Do not use for
Do not use it for other Hodgkin lymphoma subtypes or for lymphoma limited to a different lymph node region. Do not assign it when the chart only says “Hodgkin lymphoma” without the required specificity.
Coding tip
Match both the histologic subtype and the anatomic site exactly as documented before selecting C81.33.
