BREAST

C50.0–C50.9 
(Except for Non-solid tumors)
 
Codes
00      None; no surgery of primary site; autopsy ONLY
 
19      Local tumor destruction, NOS
No specimen was sent to pathology for surgical events coded 19 (principally for cases diagnosed prior to January 1, 2003).
 
20      Partial mastectomy, NOS; less than total mastectomy, NOS
         21      Partial mastectomy WITH nipple resection
         22      Lumpectomy or excisional biopsy
         23      Reexcision of the biopsy site for gross or microscopic residual disease
         24      Segmental mastectomy (including wedge resection, quadrantectomy, tylectomy)
Procedures coded 20–24 remove the gross primary tumor and some of the breast tissue (breast-conserving or preserving). There may be microscopic residual tumor.
 
30      Subcutaneous mastectomy
A subcutaneous mastectomy is the removal of breast tissue without the nipple and areolar complex or overlying skin.  It is performed to facilitate immediate breast reconstruction.  Cases coded 30 may be considered to have undergone breast reconstruction.
 
40      Total (simple) mastectomy
         41      WITHOUT removal of uninvolved contralateral breast
         43      Reconstruction NOS
                        44      Tissue
                        45      Implant
                        46      Combined (Tissue and Implant)
         42      WITH removal of uninvolved contralateral breast
         47      Reconstruction NOS
                        48      Tissue
                        49      Implant
                        75      Combined (Tissue and Implant)
A total (simple) mastectomy removes all breast tissue, the nipple, and areolar complex. An axillary dissection is not done.
For single primaries only, code removal of involved contralateral breast under the data item Surgical Procedure/Other Site (NAACCR Item #1294) or Surgical Procedure/Other Site at This Facility (NAACCR Item #674).
If contralateral breast reveals a second primary, each breast is abstracted separately. The surgical procedure is coded 41 for the first primary. The surgical code for the contralateral breast is coded to the procedure performed on that site.
Reconstruction that is planned as part of first course treatment is coded 43-49 or 75, whether it is done at the time of mastectomy or later. 
 

76      Bilateral mastectomy for a single tumor involving both breasts, as for bilateral inflammatory carcinoma
 

50      Modified radical mastectomy
         51      WITHOUT removal of uninvolved contralateral breast
         53      Reconstruction, NOS
                        54      Tissue
                        55      Implant
                        56      Combined (Tissue and Implant)
 
         52      WITH removal of uninvolved contralateral breast
                        57      Reconstruction, NOS
                        58      Tissue
                        59      Implant
                        63      Combined (Tissue and Implant)
         Removal of all breast tissue, the nipple, the areolar complex, and variable amounts of breast skin in continuity with the axilla. The specimen may or may not include a portion of the pectoralis major muscle.
If contralateral breast reveals a second primary, it is abstracted separately. The surgical procedure is coded 51 for the first primary. The surgical code for the contralateral breast is coded to the procedure performed on that site.
For single primaries only, code removal of involved contralateral breast under the data item       Surgical Procedure/Other Site (NAACCR Item #1294) or Surgical Procedure/Other Site at This Facility (NAACCR Item #674).
 
60      Radical mastectomy, NOS
         61      WITHOUT removal of uninvolved contralateral breast
                        64      Reconstruction, NOS
                        65      Tissue
                        66      Implant
                        67      Combined (Tissue and Implant)
         62      WITH removal of uninvolved contralateral breast
                        68      Reconstruction, NOS
                        69      Tissue
                        73      Implant
                        74      Combined (Tissue and Implant)
 
70      Extended radical mastectomy
         71      WITHOUT removal of uninvolved contralateral breast
         72      WITH removal of uninvolved contralateral breast
 
80      Mastectomy, NOS
 
         Specimen sent to pathology from surgical events 20–80.
 
90      Surgery, NOS
 
99         Unknown if surgery performed; death certificate ONLY
