CS Site-Specific Factor 1

Measured Thickness (Depth)

Notes

**Note 1**: Code measured thickness (depth) of tumor, not size. Depth for Merkel cell carcinoma of skin is similar to Breslow tumor depth in melanoma of the skin. Record the actual measurement in tenths of millimeters (mm) from the pathology report. **Note 2**: If tumor depth is noted on multiple specimens (two or more), record the greatest vertical or depth measurement noted on a single specimen; do not add measurements together. Record in CS Site-Specific Factor 19 that the tumor was transected. **Note 3**: If tumor is in situ (CS Extension code 000), code measured thickness as 999.
