Mature B-cell leukemia Burkitt-type not achieve remission

This code signifies a diagnosis of mature B-cell leukemia, specifically of the Burkitt-type, where the disease has not yet responded to treatment and remains active. It indicates a primary, aggressive hematologic malignancy originating from B-lymphocytes, characterized by rapid proliferation.

Apply this code when documentation explicitly states a diagnosis of Burkitt-type leukemia that has not achieved remission. This is typically used for initial diagnoses or during active treatment phases where remission has not been attained. Supporting documentation includes pathology reports confirming Burkitt-type morphology and clinical notes indicating ongoing disease activity.

• Ensure documentation specifies "Burkitt-type" and "not having achieved remission" to use this code.
• Distinguish from other mature B-cell leukemias or lymphomas; this code is specific to the Burkitt-type.
• Do not use if the patient is in remission, even partial; a different code would be appropriate for those scenarios.
