Question:

First course treatment/Histology--Lymphoma: What treatment, if any, is coded for a patient with methotrexate induced lymphoma when the treatment plan is to take the patient off methotrexate? Also, is there a specific histology for drug induced lymphoma? See Discussion.

Discussion:

Diffuse Large B-cell Lymphoma of soft palate & nasal septum, methotrexate induced, in 5/07. Patient was taken off methotrexate with complete resolution of disease. No other treatment was given. Patient was on methotrexate for treatment of rheumatoid arthritis.

Answer:

For cases diagnosed prior to 1/1/2010:Treatment: Code the treatment fields to 00 [not done] in this case.

Document the discontinuation of methotrexate for rheumatoid arthritis in a text field.

Histology: Assign code 9680/36 [Malignant lymphoma, large B-cell, diffuse, NOS]. There is no specific histology code for therapy-related lymphoma.

For cases diagnosed 1/1/10 and later, refer to the Hematopoietic and Lymphoid Neoplasm Case Reportability and Coding Manual and the Hematopoietic Database (Hematopoietic DB) provided by SEER on its website to research your question. If those resources do not adequately address your issue, submit a new question to SINQ.
