"notes" : "**Note 1:** The mitotic count, the number of mitoses per 40 high-power fields (HPF), reflects the potential aggressiveness or prognosis of uveal melanomas. This site-specific factor presumes the denominator of 40 HPF, so just the numerator (the mitotic count) is coded here. \n* For other schemas in which mitotic count is collected, the denominator may vary\n\n**Note 2:** An HPF usually has a magnification objective of 40 (a 40x field). As described in the AJCC chapter on uveal melanomas, the typical field area is 0.15 - 0.19 square millimeters (mm). (1)\n\n**Note 3:** Record mitotic count to the nearest tenth as documented in the pathology report. \n* For example, a mitotic count of 6/40 HPF would be coded 060\n\n**Note 4:** Code the specific mitotic count only per 40 HPF; assume the denominator is 40 HPF if not specified. \n* Use code 996 only if the mitotic count is expressed with a specific denominator other than 40 HPF",
