Hodgkin lymphoma, unspecified, spleen

This code signifies a diagnosis of Hodgkin lymphoma where the specific subtype is not documented, and the disease is localized to or primarily involves the spleen. It indicates a malignant proliferation of Reed-Sternberg cells within the splenic tissue, without further specification of the histological variant.

This code is appropriate when the physician's documentation confirms Hodgkin lymphoma affecting the spleen, but the pathology report or clinical notes do not specify the particular type (e.g., nodular sclerosis, mixed cellularity). It should be used when the spleen is identified as the primary or sole site of involvement for an unspecified Hodgkin lymphoma.

• Only use this code when the specific subtype of Hodgkin lymphoma is truly unknown or not documented.
• Always review pathology reports for definitive histological classification to avoid using an "unspecified" code when a more specific one is available.
• Sequence this code as the primary diagnosis when the Hodgkin lymphoma of the spleen is the reason for the encounter.
