About the C51–C58 Code Range
ICD-10 codes C51-C58 specifically classify malignant neoplasms affecting the female genital organs, including the vulva, vagina, cervix, uterus, ovaries, and related structures. These codes are essential for identifying and coding various primary cancers and their specific locations within the female reproductive system.
The range covers cancers such as vulvar malignancies (C51), including tumors of the labium majus or minus and clitoris; vaginal cancers (C52); cervical cancers, differentiated by endocervix and exocervix sites (C53); malignant neoplasms of the uterus, including the corpus, endometrium, and myometrium (C54-C55); ovarian cancers, including unilateral or bilateral presentations (C56); and malignancies of other female genital organs such as fallopian tubes, broad and round ligaments, and parametrium (C57). Each code also relates to numerous synonyms like "Primary carcinoma of Bartholin gland" for C51.0 or "Endometrioid carcinoma of endometrium" under C54.1. The inclusion of placenta malignancies under C58, including choriocarcinoma and gestational trophoblastic disease, highlights the comprehensive scope. These codes guide precise clinical documentation and facilitate accurate cancer type identification in female reproductive health.
