- (M-8247)
- C51.0 Labium majus
- C51.1 Labium minus
- C51.2 Clitoris
- C51.8 Overlapping lesion of vulva
- C51.9 Vulva, NOS
- Note 1: This schema is used for Merkel Cell.
- Note 2: The AJCC 7th edition stages cancer of the perineum with vulva. Cancer of the perineum can be coded to several different primary site codes each of which includes sites other than perineum. In addition, basal and squamous cell carcinomas of the skin of the perineum would be coded to C44.5 and would not be reportable. Involvement of the vulva and perineum should be assigned to vulva as the primary site in the absence of a statement that the tumor extended from the perineum to the vulva. CS only includes C51.0-C51.9 (vulva) and does not include primaries of the perineum in this schema.
