Inquiry Details
References:
Heme & Lymph Manual & DB
Question:
Primary site--Heme & Lymphoid Neoplasms: Does Rule PH27 apply meaning that primary site is coded to C809 or would it be more appropriate to code to C269 GI Tract NOS since all disease involves the GI tract and this is more specific?
Extranodal lymphoma first diagnosed in the stomach (fundus and antrum) which upon further investigation also involved the small bowel (MALT Lymphoma) in the absence of lymph node findings. MD staged this IIE. Initial thought was Gastric, but PET/CT indicated abnormal uptake involving loop of distended small bowel in the pelvis.
Discussion:
Answer:
Assign C269 for Gastrointestinal tract, NOS. Apply Rule PH24, code to the organ when only an organ is involved. This rule can be used for NOS sites such as GI tract, NOS.
Based on the information provided, this lymphoma is confined to the GI tract -- stomach and small bowel.
