Vulva

Note 1: The Federation Internationale de Gynecologie et d'Obstetrique (FIGO) stage definitions do not include Stage 0 (Tis) for vulvar cancer. Use code 987 for any case where CS Extension is coded 000.
Note 2: Code the FIGO stage as stated in the medical record. When lymph node(s) is/are clinically or pathologically positive or metastasis is present, make sure that the FIGO stage reflects the combination of T, N, and M and NOT just the T. If a stage group is stated but it does not specify that it is a FIGO stage, assume that it is a FIGO stage and code it. Do not attempt to code FIGO stage based only on T, N, and M. If you cannot make a determination of stage based on the previous information, use code 999, stage unknown.
