Hodgkin lymphoma, unspecified, intrapelvic lymph nodes

This code signifies a diagnosis of Hodgkin lymphoma where the specific subtype is not documented, and the disease is located within the lymph nodes of the pelvic region. It indicates a primary malignancy affecting the lymphatic system, specifically within the pelvis, without further pathological classification.

This code is appropriate when documentation confirms Hodgkin lymphoma affecting intrapelvic lymph nodes, but the pathologist has not yet specified the histological subtype (e.g., nodular sclerosis, mixed cellularity). It should be used when the physician's diagnosis explicitly states "Hodgkin lymphoma, unspecified" with involvement of pelvic lymph nodes.

• Ensure documentation clearly specifies "intrapelvic lymph nodes" as the site of involvement.
• Avoid using this code if a more specific histological subtype of Hodgkin lymphoma is identified; instead, use the appropriate subcategory.
• Always sequence this code as a primary diagnosis when it is the reason for the encounter, or as a secondary diagnosis if the patient is being treated for complications or other related conditions.
