Question:

Reason no treatment/Surgery of Primary Site: Does the "Reason for No Cancer-Directed Therapy" field only relate to the "Surgery of Primary Site" field? If so, for what diagnosis years is that effective? Have SEER's coding guidelines changed over time? See discussion.

Discussion:

Whenever a surgical procedure is performed that results in a non 0 or 9 code in any one of the Surgery fields, should the Reason for No Site-Specific Surgery field be coded to 0 [Cancer-directed surgery performed]?

Answer:

For cases diagnosed 2003 and forward: The field "Reason for No Surgery of Primary Site" applies only to surgery of primary site. This is a change from the pre-2003 instructions.

History:

For cases diagnosed 1998-2002: Surgery of Primary Site, Scope of Regional Lymph Node Surgery, and Surgical Procedure of Other Site are all surgical procedures. If any of these fields have a valid procedure code, Reason for No Cancer-Directed Surgery must be coded as 0 [Cancer-directed surgery performed].
