Histology--Heme & Lymphoid Neoplasms: What histology code should I use? See discussion.
Not sure if I code this as a new primary from the NHL in 2005?
Quoted directly from history and physical: NHL (Nodular Histiocytic Lymphoma) in 2005 status post chemo. Now enlarged right axillary lymph nodes with path lymph node core biopsy confirmed B-cell Small Lymphocytic Lymphoma/Chronic Lymphocytic Leukemia flow cytometric most consistent with B-cell Chronic Lymphocytic Leukemia.
Here are the steps to follow:
Use ICD-O-3 to find the histology code for the 2005 diagnosis. The histology code for nodular histiocytic lymphoma is 9698/3. Use the 2012 heme database to find the histology code for B-cell small lymphocytic lymphoma/chronic lymphocytic leukemia, 9823/3.
Next, go to the M rules. M13 applies and you are instructed to go to the hematopoietic database. Comparing 9898/3 and 9823/3 using the multiple primaries calculator shows the small lymphocytic lymphoma/chronic lymphocytic leukemia, 9823/3, is a new primary.
