Malignant neoplasm of uterus, part unspecified (C55)

The ICD-10 code C55 is used to classify a malignant tumor of the uterus when the specific part of the uterus affected is not detailed. This code covers cancers identified as originating in the uterus but without precise localization to the cervix or corpus.

This code includes conditions such as primary malignant neoplasm of uterus and synonyms like carcinosarcoma, adenosarcoma, leiomyosarcoma, and adenocarcinoma of the uterus. It also applies when the malignant tumor extends directly to nearby organs like the rectum, urinary bladder, vagina, vulva, fallopian tubes, or ovaries. Using ICD-10 code C55 helps medical coders and healthcare professionals document cases where the uterine cancer cannot be precisely located, ensuring accurate capture of cancer cases involving the uterus in cancer registries and clinical records.
