Inquiry Details
References:
SEER*Rx
Question:
First course treatment/Chemotherapy: Can a drug be coded as treatment for primary sites or histologies not listed for that drug in the SEER*Rx Database? See Discussion.
Discussion:
The patient was diagnosed with chronic myelogenous leukemia in 2008 followed by a diagnosis of chronic lymphocytic leukemia in 2011. Per the physician statement, the patient started nilotinib in 10/2011 for CML.
The SEER*Rx Database lists CML and GIST as the only primary site/histology combinations treated using nilotinib. Can nilotinib also be coded as treatment for the CLL primary?
Answer:
SEER*Rx lists the approved sites/histologies for each drug. However, if you have a physician statement that indicates the drug was given for another site/histology, code the agent as treatment for that site/histology.
