Acute leukemia of unsp cell type not achieve remission

This code signifies a diagnosis of acute leukemia where the specific cell lineage (e.g., myeloid, lymphoid) has not been determined or documented. The "not having achieved remission" component indicates that the patient is currently in an active phase of the disease, not in a period of temporary or complete absence of disease signs and symptoms.

This code is appropriate when a patient presents with acute leukemia, and the pathology report or physician documentation does not specify the cell type. It should be used for initial diagnoses or during active treatment phases where remission has not yet been attained. Documentation must clearly state "acute leukemia, unspecified cell type" and indicate the absence of remission.

• Avoid using this code if the specific cell type (e.g., acute lymphoblastic leukemia, acute myeloid leukemia) is documented; instead, code to the more specific diagnosis.
• Ensure documentation explicitly states "not having achieved remission" or implies active disease; otherwise, consider codes for leukemia in remission.
• This code is often a temporary assignment until further diagnostic workup clarifies the specific type of acute leukemia.
