CS Site-Specific Factor 20
Assessment of Positive Distant Metastases
Notes
**Note 1**: Code the assessment method used for determining the presence of metastasis as coded in CS Mets at DX, CS Mets at DX - Bone, CS Mets at DX - Brain, CS Mets at DX - Liver, and CS Mets at DX - Lung. If CS Mets at DX is coded as 00 (no positive metastasis), this field must be coded 000. **Note 2**: If multiple methods of assessments determined positive metastases, use the highest code that applies. See CSv2 General Rules Part I for types of tests to be included.Default
