ICD-10 Code C81.93 – Hodgkin lymphoma, unspecified, intra-abdominal lymph nodes (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code C81.93 – Hodgkin lymphoma, unspecified, intra-abdominal lymph nodes
What it is
This code identifies Hodgkin lymphoma when the site is intra-abdominal lymph nodes and the subtype is not specified. It tells you the disease is in abdominal nodes, but the exact Hodgkin type is not documented.
Clinical signs
Clinical features vary; refer to documentation. Common findings may include enlarged abdominal lymph nodes on imaging, abdominal discomfort, or systemic “B” symptoms, but you should code only what is documented.
When to use this code
Use C81.93 when the record clearly states Hodgkin lymphoma involving intra-abdominal lymph nodes and no more specific subtype is given. It is also appropriate when the clinician documents “unspecified Hodgkin lymphoma” with abdominal nodal involvement. If the site or histology is more specific, choose the documented code instead.
Do not use for
Do not use this code for non-Hodgkin lymphoma, other lymphoma sites, or Hodgkin lymphoma with a documented specific subtype. Check documentation if the chart only mentions abdominal mass or generalized lymphadenopathy.
Coding tip
Code the exact nodal site and lymphoma type separately in your review, and default to the most specific documented option available.
