"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 category.\n\n**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.\n\n* Poorly differentiated/Undifferentiated (grade 3 or 4)\n* Depth greater than 2 millimeters (mm) thickness\n* Clark level IV or V\n* Perineural invasion\n\n**Note 3**: Use codes 991, 992, and 993 only if no specific information is available about the high risk features, but the record contains a general statement about the presence of high risk features. \n\n**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.",
