Mature B-cell leukemia Burkitt-type, in relapse

This code represents a specific type of mature B-cell leukemia, characterized by its Burkitt-type morphology, that has recurred after a period of remission. It signifies a relapse of this aggressive hematologic malignancy, which originates from B-lymphocytes.

Use this code when documentation clearly indicates a diagnosis of Burkitt-type mature B-cell leukemia and specifies that the disease is currently in relapse. This typically follows initial treatment and a period of disease-free status, with subsequent evidence of disease recurrence.

• Ensure documentation explicitly states "Burkitt-type" and "in relapse" for accurate code assignment.
• Do not confuse with initial diagnosis or remission codes for this condition.
• Sequence as the primary diagnosis when it is the reason for the encounter.
