        Description
            "Separate tumor nodules" refers to what is conceptually a single tumor with intrapulmonary metastasis in the ipsilateral (same) lung. Their presence in the same or different lobes of lung from the primary tumor affects the T and M categories.
        Rationale
                This data item was previously collected for Lung, SSF# 1 and at least one standard setter is continuing to collect it.
            Codes
                | 0 | No separate tumor nodules; single tumor only Separate tumor nodules of same histologic type not identified/not present Intrapulmonary metastasis not identified/not present Multiple nodules described as multiple foci of adenocarcinoma in situ or minimally invasive adenocarcinoma | 
| 1 | Separate tumor nodules of same histologic type in ipsilateral lung, same lobe | 
| 2 | Separate tumor nodules of same histologic type in ipsilateral lung, different lobe | 
| 3 | Separate tumor nodules of same histologic type in ipsilateral lung, same AND different lobes | 
| 4 | Separate tumor nodules of same histologic type in ipsilateral lung, unknown if same or different lobe(s) | 
| 7 | Multiple nodules or foci of tumor present, not classifiable based on notes 3 and 4 | 
| 8 | Not applicable: Information not collected for this case (If this item is required by your standard setter, use of code 8 will result in an edit error.) | 
| 9 | Not documented in medical record Primary tumor is in situ Separate Tumor Nodules not assessed or unknown if assessed | 
Code Notes
                Each Site-Specific Data Item (SSDI) applies only to selected primary sites, histologies, and years of diagnosis. Depending on applicability and standard-setter requirements, SSDIs may be left blank.
