Abstractor Notes
This NOS histology is a generic disease description. DCO cases or path report only cases may stay in this classification. In most cases, an NOS histology is only the working diagnosis; the physician will run further diagnostic procedures and look for various clinical presentations to identify a more specific disease. Further review of the medical record should be done to look for the tests listed as definitive diagnosis. When a more specific diagnosis is identified, the histology should be changed to the more specific neoplasm name and code. For 9590/3 malignant lymphoma, NOS, non-Hodgkin lymphoma, classical Hodkin lymphoma, and any specific Hodgkin and non-Hodgkin lymphomas would be a more specific histology.

See the histology tables for more information on NOS and more specific histologies.
