Enteropathy-type (intestinal) T-cell lymphoma, in remission

This code represents a rare and aggressive form of non-Hodgkin lymphoma originating from T-cells in the small intestine, specifically when the disease is no longer active and the patient is in a state of remission. It signifies that the characteristic malignant T-cells are currently undetectable or significantly reduced following treatment.

Use this code when documentation explicitly states a diagnosis of enteropathy-type T-cell lymphoma and indicates that the patient is currently in remission. This typically follows successful chemotherapy, radiation, or stem cell transplant. Supporting documentation would include pathology reports confirming the diagnosis and oncologist notes confirming the remission status.

• Ensure documentation clearly specifies "remission" for enteropathy-type T-cell lymphoma; do not use for active disease or history of.
• Do not confuse with other types of T-cell lymphomas or intestinal lymphomas; specificity is key.
• Sequence this code as a secondary diagnosis if the patient is receiving ongoing treatment for a complication or sequela related to the lymphoma or its treatment.
