Grade Clinical
Notes
**Note 1:** Clinical grade must not be blank.
**Note 2:** Assign the highest grade from the primary tumor assessed during the clinical time frame.
**Note 3:** G3 includes anaplastic.
**Note 4:** 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 5:** If there is only one grade available and it cannot be determined if it is clinical or pathological, assume it is a clinical grade and code appropriately per clinical grade categories for that site, and then code unknown (9) for pathological grade, and blank for post therapy grade.
