ICD-10 Code C53 – Malignant neoplasm of cervix uteri (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code C53 – Malignant neoplasm of cervix uteri
What it is
C53 identifies a malignant tumor arising in the cervix uteri, the lower part of the uterus that opens into the vagina. Use it when the chart documents cervical cancer, unless a more specific site or histology is recorded.
Clinical signs
Clinical features vary; refer to documentation. Commonly recorded findings include abnormal vaginal bleeding, postcoital bleeding, pelvic pain, or an abnormal cervical exam, but diagnosis should be supported by pathology or other clinician-documented evidence.
When to use this code
Use C53 when the provider documents primary malignant neoplasm of the cervix uteri, including confirmed cervical cancer on biopsy or in the assessment. It may also apply when the record clearly identifies cervical cancer without further subsite detail. Check documentation if the note only states abnormal Pap results or dysplasia.
Do not use for
Do not use C53 for benign cervical conditions, cervical dysplasia, or abnormal screening tests alone. If the documentation describes carcinoma in situ, metastasis to the cervix, or another gynecologic site, code the documented condition instead.
Coding tip
Confirm whether the neoplasm is primary, in situ, or metastatic before assigning C53.
