Extrnod mrgnl B-cell lymph mucosa-assoc lym tiss, in remis

This code signifies a history of extranodal marginal zone B-cell lymphoma, specifically of the mucosa-associated lymphoid tissue (MALT lymphoma), where the disease is currently in a state of remission. This means the patient previously had this type of low-grade non-Hodgkin lymphoma originating from mucosal sites, but there is no current evidence of active disease.

Apply this code when documentation confirms a past diagnosis of MALT lymphoma and the patient is currently free of disease, as evidenced by clinical, radiological, or pathological findings. This code is appropriate for follow-up encounters, surveillance, or when the patient is being treated for unrelated conditions but their MALT lymphoma history in remission is relevant to their overall health status.

• Ensure documentation explicitly states "in remission" or "history of" with no evidence of active disease.
• Do not use this code if there is any indication of active MALT lymphoma; instead, code the active disease.
• Consider sequencing this code after any active conditions being treated during the encounter, unless the remission status is the primary reason for the visit.
