Percentage of Non-Endometrioid Cell Type in Mixed Histology Tumors

Notes

**Note 1:** Adenocarcinomas with mixed histology are graded according to the percentage of non-squamous or non-morular solid growth pattern. Morular growth pattern refers to well-defined, circumscribed, solid round nests of cells that fill and expand endometrial glands. **Note 2:** Code based on the percentage of non-endometrioid cell type as stated on the pathology report. Only use a statement of Grade 1, Grade 2, or Grade 3 if it is based on the growth pattern. * If grade based on growth pattern is not specified, use code 999
