Leukemia, unspecified not having achieved remission

This code signifies a diagnosis of leukemia where the specific type (e.g., acute myeloid, chronic lymphocytic) has not been documented or determined. Importantly, it indicates that the patient has not achieved remission from their leukemia. This represents an active, undifferentiated form of the disease.

This code is appropriate when the medical record clearly states a diagnosis of "leukemia, unspecified" and explicitly notes that the patient is not in remission. It is used for initial diagnoses of leukemia where further classification is pending, or when the physician has not specified the type of leukemia. Documentation should confirm the presence of leukemia and the absence of remission.

• Do not use this code if a more specific type of leukemia (e.g., C92.00 for acute myeloid leukemia) is documented.
• Ensure documentation explicitly states "not in remission"; otherwise, consider codes for unspecified leukemia in remission (C95.91) or without mention of remission status (C95.90, but this code specifically states "not having achieved remission").
• Always query the provider for a more specific leukemia type if possible, as this code is less specific and may impact reimbursement or data analysis.
