About the C53 Code Range

The ICD-10 code C53 and its subcategories are used specifically for coding malignant neoplasms of the cervix uteri, which means cancers originating in the cervix. These codes allow precise identification of cancer location within the cervix, aiding proper diagnosis and treatment documentation.

The ICD-10 code for malignant neoplasm of cervix uteri C53 encompasses several specific sites: C53.0 refers to cancer of the endocervix, also known as endocervical adenocarcinoma or primary carcinoma of the cervix. C53.1 denotes malignancy in the exocervix, including primary carcinoma or carcinoma of the cervix’s outer portion. The code C53.8 covers overlapping tumors involving multiple adjacent cervical sites, such as the squamocolumnar junction. When the cancer location is not precisely specified, C53.9 is used, capturing various forms including squamous cell carcinoma, adenosquamous carcinoma, and rare types like adenoid cystic carcinoma or primitive neuroectodermal tumors. Understanding these synonyms and precise ICD-10 codes ensures correct coding for different cervical cancer presentations.
