Lymphoid leukemia, unspecified not having achieved remission

This code signifies a diagnosis of lymphoid leukemia where the specific type (e.g., acute, chronic, B-cell, T-cell) is not documented, and the patient has not yet achieved remission. It indicates an active, undifferentiated lymphoid malignancy.

Use this code when the medical record clearly states lymphoid leukemia but lacks further specification regarding its type or stage of remission. This applies to initial diagnoses or follow-up encounters where remission has not been achieved or is not documented. Documentation should explicitly state "lymphoid leukemia, unspecified" and confirm the absence of remission.

• Do not use if a more specific type of lymphoid leukemia (e.g., acute lymphoblastic leukemia) is documented.
• Always sequence as the primary diagnosis if it is the reason for the encounter.
• Ensure documentation explicitly states "not having achieved remission" or implies active disease without remission.
