Question:
Date Therapy Initiated/Reason no treatment--Lymphoma: Is the date of the lymph node biopsy used as the date of treatment if the lymph node biopsy is the first treatment or the only treatment performed? Is the reason for no surgery coded to 0 [Surgery of the primary site was performed]?
Discussion:
Answer:
For cases diagnosed prior to January 1, 2008, enter the date of the lymph node biopsy (excisional biopsy or biopsy NOS) as the Date Therapy Initiated for a lymphoma when the biopsy is the first or only therapy performed.
Code Reason for No Surgery of Primary Site as 0 [Surgery of the primary site was performed] and the biopsy of a lymph node is coded to 25 in Surgery to Primary Site.
Do not code a fine needle aspiration or core needle biopsy in Surgery of Primary Site.
