ICD-10 Code C81.03 – Nodular lymphocyte predominant Hodgkin lymphoma, intra-abdominal lymph nodes (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code C81.03 – Nodular lymphocyte predominant Hodgkin lymphoma, intra-abdominal lymph nodes
What it is
This code identifies nodular lymphocyte predominant Hodgkin lymphoma involving intra-abdominal lymph nodes. Use it when documentation specifies this lymphoma subtype and the nodal site is within the abdomen.
Clinical signs
Clinical features vary; refer to documentation. Standard references describe lymph node enlargement and lymphoma confirmed by pathology, with the nodular lymphocyte predominant subtype specifically identified.
When to use this code
Use C81.03 when the provider documents nodular lymphocyte predominant Hodgkin lymphoma affecting intra-abdominal lymph nodes. It also fits when pathology or oncology notes clearly localize the disease to abdominal nodes. Check documentation if the record only says Hodgkin lymphoma without subtype or site.
Do not use for
Do not use this code for other Hodgkin lymphoma subtypes or for unspecified nodal involvement. If the chart does not confirm intra-abdominal lymph nodes, check documentation before assigning C81.03.
Coding tip
Code the documented subtype and anatomic site together; if either is missing, query the record before coding.
