High Risk Features
Notes
**Note 1**: For AJCC 7 staging, the T category is not only dependent on tumor size but also on several high risk features that can upgrade the T assignment. **Note 2**: Based on the information in the medical record, the registrar is required to count and code the number of high risk features (each feature equals 1 risk factor). If specific information is available about some but not all of the high risk features, count the number of features documented in the record. * Poorly differentiated/Undifferentiated (grade 3 or 4) * Depth greater than 2 millimeter (mm) thickness * Clark level IV or V * Perineural invasion * Primary site: skin of external ear (C44.2) OR skin of lip (hair-bearing, also called non-glabrous lip) (C44.0) **Note 3**: Use codes 991, 992, and 993 only if no specific information is available about the high risk features (other than primary site), but the record contains a general statement about the presence of high risk features. **Note 4**: The definition of high risk features was changed with the release of CSv2:V0203: Lymph-vascular invasion was removed as a high-risk feature, and tumor depth was changed from greater than or equal to 4 mm to greater than 2 mm. All cases with codes 000-004 coded in or updated to CSv2:V0202 should be reviewed and the correct number of high-risk features determined and coded.Default
