What This Code Means

A rare lymphoma of the intestines caused by abnormal T-cells that is currently in remission.

Coding Tips

• •Document the specific intestinal location if available
• •Confirm remission status is explicitly stated in clinical notes

Clinical Significance

Enteropathy-type intestinal T-cell lymphoma in remission represents a rare but meaningful clinical outcome in a disease with typically poor prognosis. Remission may be achieved through aggressive chemotherapy, potentially combined with surgical resection. These patients require ongoing surveillance for both lymphoma relapse and management of underlying celiac disease or other enteropathy.

Documentation Requirements

• ✓Remission must be explicitly documented by the provider with supporting evidence from imaging and endoscopic surveillance.
• ✓The underlying enteropathy (typically celiac disease) should be documented along with adherence to dietary restrictions.
• ✓Surveillance schedule and monitoring for treatment-related complications must be recorded.
