Site-Specific Factor 12
High Risk Features
Notes
**Note 1:** For TNM 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 (C442) OR skin of lip (hair-bearing, also called non-glabrous lip) (C440) **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.Default
