Chronic lymphocytic leukemia of B-cell type in remission

This code signifies a chronic B-cell lymphoproliferative disorder characterized by an accumulation of mature-appearing lymphocytes, currently in a state of remission. It indicates that the patient previously had active chronic lymphocytic leukemia (CLL) of the B-cell type, but the disease is no longer clinically detectable or active.

Apply this code when documentation explicitly states a diagnosis of chronic lymphocytic leukemia, B-cell type, and specifies that the disease is currently in remission. This typically follows successful treatment, such as chemotherapy or immunotherapy, where the patient no longer exhibits signs or symptoms of active disease.

• Always confirm the specific cell type (B-cell) and the remission status from the physician's documentation.
• Do not use this code for active disease or for other types of leukemia.
• Consider sequencing this code after any codes for complications or ongoing treatment related to the patient's history of CLL.
