FIGO Stage Ovary, Fallopian Tube, and Primary Peritoneal Carcinoma
Notes
**Note 1:** There must be a statement about FIGO stage from the managing physician in order to code this data item * Do **not** code FIGO stage based on the pathology report * Do **not** code FIGO stage based only on T, N, M * If "FIGO" is not included with a stated stage, then do **not** assume it is a FIGO stage **Note 2:** FIGO stage is not the same thing as FIGO grade. Only code FIGO stage in this field, do not code FIGO grade. * Code FIGO grade in the grade fields **Note 3:** If there is more than one FIGO stage provided from the clinical and pathological work up, code the most extensive FIGO stage. **Note 4:** For High-grade serous carcinoma (HGSC) or serous tubal intraepithelial carcinoma (STIC) (8441/2), assign the FIGO stage based on the managing physician's documentation of FIGO. (See Note 1) * If FIGO stage for HGSC or STIC is not documented by the managing physician, code unknown (code 99) * Do not code 97 (in situ) for HGSC or STIC since FIGO does not have a Stage 0 * If diagnosis is low grade serous intraepithelial carcinoma (LGSC) (8441/2) or serous intraepithelial carcinoma (no grade stated) (8441/2), code 97 **Note 5:** Code 97 for any remaining in situ histologies (/2) since the FIGO stage definitions do not include Stage 0.| Code | Description |
