CS Site-Specific Factor 20
Assessment of Positive Distant Metastases

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.

010	Physical examination or laboratory tests only
020	Radiography,imaging: Ultrasound (US) Computed tomography scan (CT) Magnetic resonance imaging (MRI) Positron emission tomography scan (PET)

040	Excisional biopsy or resection with microscopic confirmation
988	Not applicable: Information not collected for this case (If this information is required by your standard setter, use of code 988 may result in an edit error.)
