C81.90
ICD-10-CMThis code signifies a diagnosis of Hodgkin lymphoma where the specific subtype (e.g., nodular sclerosis, mixed cellularity) has not been determined or documented. It also indicates that the primary site of the lymphoma is not specified in the medical record.
Use this code when the physician's documentation confirms a diagnosis of Hodgkin lymphoma but lacks further specificity regarding the histological type or the anatomical location of the primary tumor. This is typically an interim or less specific diagnosis, often used when initial pathology results are pending or incomplete.
