Surgical Margins (CoC) Residual Primary Tumor Following Cancer-Directed Surgery (pre-96 CoC)	1320	1	CoC	1574-1574

Description
Codes describe the final status of surgical margins after resection of the primary tumor. See also RX Summ--Surg Prim Site [1290].

Rationale
This item serves as a quality measure for pathology reports, is used for staging, and may be a prognostic factor in recurrence. This item is not limited to cases that have been staged. It applies to all cases that have a surgical procedure of the primary site.

Codes (Refer to the most recent version of FORDS for additional instructions.)

0	No residual tumor
1	Residual tumor, NOS
2	Microscopic residual tumor
3	Macroscopic residual tumor
7	Margins not evaluable
8	No primary site surgery
9	Unknown or not applicable

Note: Codes were site specific (1998-2002), and have been changed to be generic across all disease sites.
