Prolymphocytic leukemia of B-cell type, in remission

This code signifies a B-cell prolymphocytic leukemia (B-PLL) that is currently in a state of remission. B-PLL is a rare and aggressive mature B-cell neoplasm characterized by the proliferation of prolymphocytes in the peripheral blood, bone marrow, and often the spleen and lymph nodes. Remission indicates a significant reduction or absence of disease signs and symptoms following treatment.

Apply this code when documentation explicitly states a diagnosis of B-cell prolymphocytic leukemia and confirms the patient is currently in remission. This typically follows a course of chemotherapy, immunotherapy, or other definitive treatment. Supporting documentation would include hematology reports, bone marrow biopsies, and physician notes indicating the current disease status as "in remission."

• Always confirm the specific cell type (B-cell) and the remission status. Do not use for T-cell prolymphocytic leukemia or if the disease is active or in relapse.
• Ensure the documentation clearly distinguishes between partial and complete remission if such detail is provided, though this code does not differentiate.
• Sequence this code as a secondary diagnosis if the patient is receiving ongoing treatment for a complication or sequela related to the past leukemia.
