Other lymphoid leukemia, in relapse

This code signifies a diagnosis of other specified types of lymphoid leukemia that has recurred or progressed after a period of remission or successful treatment. It indicates that the patient's disease, which is not otherwise classified as acute or chronic lymphocytic leukemia, is currently active again.

Apply this code when documentation explicitly states "other lymphoid leukemia in relapse" or similar phrasing indicating recurrence of a non-specific lymphoid leukemia. This code is appropriate when the patient is undergoing treatment for a relapse of a previously diagnosed, but not precisely specified, lymphoid leukemia.

• Ensure documentation clearly specifies "relapse" or "recurrent" for the "other lymphoid leukemia."
• Do not use this code for initial diagnoses or for lymphoid leukemias explicitly classified as acute or chronic lymphocytic leukemia (CLL/ALL).
• Always sequence this code after any codes for current manifestations or complications of the relapse.
