Surgery of Primary Site (SEER/CoC)
Cancer-Directed Surgery (pre-96 CoC)
1646 2 SEER/CoC 1620 - 1621
Description
Site-specific codes for the type of surgery to the primary site performed as part of the first course of treatment. This includes treatment given at all facilities as part of the first course of treatment. This field is to be used for ROADS codes after the ROADS to FORDS conversion. It is also to be used to code Surgery Primary Site at all facilities for all tumors diagnosed before January 1, 2003.
Rationale
If central registries wish to study the treatment given at particular hospitals, the hospital-level treatment fields must be used.
Codes (in addition to the site-specific codes)
00 No primary site surgery performed
99 Unknown if primary site surgery performed
Note: See the CoC ROADS Manual, 1998 Supplement, CoC Coding System [2140] code 7, and the SEER Program Code Manual, RX Coding System [1460] code 5, 1998 for site-specific codes.
