SEER is an authoritative source of information on cancer incidence and survival in the United States. SEER currently collects and publishes cancer incidence and survival data from population-based cancer registries covering approximately 28 percent of the U.S. population.
Lymph nodes (C770-C779) are the usual primary sites; however, involvement in other sites is possible. If you have confirmation that the only involved site is something other than the lymph nodes, than code to that primary site. See Module 7.
Subtype of Hodgkin lymphomalymphocyte depletion, characterized by extremely large numbers of Hodgkin and Reed-Sternberg cells, some of which appear to be mummified. Diffuse effacement of normal lymph node structure; small lymphocytes, plasma cells, histiocytes, granulocytes are scanty. Foci of necrosis usually encountered.
Hodgkin lymphoma, lymphocyte depletion includes diffuse fibrosis and reticular Hodgkin's disease from the Lukes and Butler classification. This neoplasm is now very rarely diagnosed, and it is recognized that many cases previously diagnosed as HD (lymphocyte-depletion) are in fact examples of non-Hodgkin's lymphoma, commonly of anaplastic large cell type Anaplastic Large Cell Lymphoma. The majority of cases of show morphological features of diffuse fibrosis characterized by a hypocellular background containing bizarre H-RS cells and associated with non-collagenous fibrosis.
This code should be used only for historic cases unless no other diagnosis is available.
Preferred primary sites are listed for this disease in the primary site field; however, involvement in other sites is possible, but rare. If you have confirmation that the only involved site is something other than the preferred primary listed, then code to that primary site.
Per WHO, Hodgkin lymphomas are primarily B-cell lymphomas. If the medical record states B-cell, code 6. Since there are Hodgkin lymphomas that are not B-cell, the default grade is 9 (unknown) where the documentation does not specifically state B-cell.
