CS Site-Specific Factor 1
Separate Tumor Nodules - Ipsilateral Lung

Note 1: Separate tumor nodules in the ipsilateral lung are coded separately from CS Extension. Separate tumor nodules in the contralateral lung are coded in CS Mets at DX.
Note 2: Separate tumor nodules can be defined clinically (by imaging) and/or pathologically.
Note 3: If separate tumor nodules are not mentioned in imaging and/or pathological reports, use code 000.
Note 4: For in situ tumors, code CS Site-Factor 1 to 000.
