CS Mets at DX

Notes

**Note 1**: Metastasis to adnexa, parametria, pelvic serosa, or vagina is coded in CS Extension. **Note 2**: When both Federation Internationale de Gynecologie et d'Obstetrique (FIGO) stage and metastatic detail are available, record the code with metastatic detail in preference to a statement of FIGO stage. **Note 3**: FIGO Stage IV, NOS is assigned based on tumor extension and/or metastasis. Code CS Mets at DX based on a physician's statement of FIGO Stage IV, NOS only if it is known that the stage value is assigned because of metastasis.
