Lymphoblastic lymphoma, nodes of ing region and lower limb

This code signifies a diagnosis of lymphoblastic lymphoma, a highly aggressive non-Hodgkin lymphoma, specifically affecting the lymph nodes located in the inguinal region (groin) and/or the lower extremities. This malignancy originates from immature lymphoid cells and can rapidly progress.

Apply this code when documentation confirms a pathological diagnosis of lymphoblastic lymphoma with primary or metastatic involvement of lymph nodes in the groin or leg. Supporting documentation will include pathology reports detailing the specific lymphoma subtype and imaging or physical exam findings indicating affected lymph node sites.

• Ensure the pathology report explicitly states "lymphoblastic lymphoma" and not another subtype of non-Hodgkin lymphoma.
• Verify that the affected anatomical sites are specifically the inguinal lymph nodes or those of the lower limb.
• Sequence this code as the primary diagnosis when it is the reason for the encounter, followed by any associated signs or symptoms.
