PUF Data Item Name: 
LATERALITY
NAACCR Item #: 
410
length: 
1
Allowable values: 
0 - 5, 9
Description: 
Identifies the side of a paired organ or the side of the body on which the reportable tumor originated. This applies to the primary site only.
Registry Coding Instructions: 
  • Code laterality for all paired sites (see Analytic Note).
  • Code all nonpaired sites 0 (see Analytic Note).
  • Record laterality for unknown primary site (C80.9) as 0 (not a paired site).
  • Do not code metastatic sites as bilateral involvement.
  • Code midline lesions 5 (see Analytic Note).
Analytic Note: 

Beginning with cases diagnosed in 2010, the code 5 is used for midline of paired sites. This code is applicable for very few sites, because it requires that the two lateral portions be contiguous (laterality of the skin of most parts of the body has a midline; laterality of the breast does not). For cases diagnosed prior to 2010, the midline was coded 9. Those cases are rare, but will be coded 9 in pre-2010 PUF cases.
