C91.Z1
ICD-10-CMThis code signifies a type of lymphoid leukemia that does not fit into more specific categories, such as acute or chronic lymphocytic leukemia, and is currently in a state of remission. Remission indicates that the signs and symptoms of the cancer have significantly decreased or disappeared, though the disease may not be completely cured. It represents a favorable response to treatment for an unspecified lymphoid leukemia.
Apply this code when documentation specifies "other lymphoid leukemia" and explicitly states that the patient is in remission. This is typically used for follow-up encounters after initial treatment, or when monitoring a patient who has achieved remission. Supporting documentation includes pathology reports confirming lymphoid leukemia and physician notes indicating the current remission status.
