Assume the denominator is 5 square mm if not specified. * Low: 5 or fewer mitoses per 5 square mm (L) * High: Over 5 mitoses per 5 square mm (H) **Note 5:** Code 9 when * Grade from primary site is not documented * Clinical workup is not done (for example, cancer is an incidental finding during surgery for another condition) * Grade checked “not applicable” on CAP Protocol (if available) and no other grade information is available **Note 6:** If there is only one grade available and it cannot be determined if it is clinical, pathological, or after neo-adjuvant therapy, assign as a clinical grade and code unknown (9) for pathological grade, and blank for post-therapy grade. **Note 7:** If you are assigning an AJCC 8th edition stage group * Grade is required to assign stage group * Codes A-D are treated as an unknown grade when assigning AJCC stage group * An unknown grade may result in an unknown stage groupDefault
