Lymphoblastic (diffuse) lymphoma, intra-abd lymph nodes

This code signifies a diagnosis of lymphoblastic lymphoma, a highly aggressive non-Hodgkin lymphoma characterized by the proliferation of immature lymphoid cells. Specifically, it indicates that the disease is located within the intra-abdominal lymph nodes, which are lymph nodes situated within the abdominal cavity.

Utilize this code when documentation confirms a pathological diagnosis of lymphoblastic lymphoma with primary or secondary involvement of lymph nodes within the abdomen. This includes findings from biopsy reports, imaging studies (e.g., CT, MRI) detailing intra-abdominal lymphadenopathy, and physician notes explicitly stating this specific anatomical involvement.

• Ensure the pathology report definitively identifies the lymphoma as "lymphoblastic" and not another subtype.
• Verify that the documentation clearly specifies intra-abdominal lymph node involvement, differentiating it from other anatomical sites.
• Code any associated signs, symptoms, or complications (e.g., abdominal pain, organ compression) as secondary diagnoses.
