Histology/Primary site--Heme & Lymphoid Neoplasms: Do I code: 9680/3 for DLBCL? Also, what topography code should I use?
A 12 year old with history of Fanconi anemia. Status post stem cell transplant x2. 5/2012 diagnosed with monomorphic B cell PTLD (post-transplant lymphoproliferative disorder) with features of diffuse large B-cell lymphoma. Sites involved: chest wall/intramuscular and right frontal lobe of brain. 2012 Hematopoietic Database states to code to lymphoma.
To assign the primary site, go to Module 7. Since there is involvement in two extranodal sites and no mention of lymph node involvement, use Rule PH37 and code to C809.
