Nodular sclerosis Hodgkin lymphoma, intrapelvic lymph nodes

This code identifies a specific subtype of Hodgkin lymphoma, nodular sclerosis, affecting lymph nodes located within the pelvic cavity. Nodular sclerosis is the most common histological subtype of Hodgkin lymphoma, characterized by collagen bands forming nodules and lacunar cells. The intrapelvic location specifies the anatomical site of involvement.

Use this code when documentation clearly states a diagnosis of nodular sclerosis Hodgkin lymphoma with confirmed involvement of lymph nodes within the pelvis. This diagnosis is typically established through biopsy and histopathological examination. Supporting documentation will include pathology reports and physician notes detailing the lymphoma subtype and anatomical location.

• Ensure the pathology report specifically identifies "nodular sclerosis" as the subtype and "intrapelvic lymph nodes" as the site of involvement.
• Do not use this code if the lymphoma is described as another subtype (e.g., mixed cellularity) or if the pelvic involvement is not explicitly stated.
• Sequence this code as the primary diagnosis when it is the reason for the encounter, followed by any associated signs, symptoms, or complications.
