ICD-10 Code C54 – Malignant neoplasm of corpus uteri (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code C54 – Malignant neoplasm of corpus uteri
What it is
C54 identifies a malignant tumor arising in the body of the uterus, also called the corpus uteri. Use it when documentation states cancer of the uterine body and does not specify a more exact subsite.
Clinical signs
Common findings include abnormal uterine bleeding, especially after menopause, pelvic pain, or an enlarged uterus. Clinical features vary; refer to documentation and confirmed pathology when available.
When to use this code
Use C54 when the record documents primary malignancy of the corpus uteri, including uterine body cancer without a more specific site. It may also apply when the provider notes endometrial or uterine corpus cancer and no other code is selected by the documentation. Check documentation for laterality or histology details; they do not change the base code.
Do not use for
Do not use C54 for malignant neoplasm of the cervix uteri or for benign uterine conditions. If the cancer is documented in another uterine site or the record is unclear, check documentation.
Coding tip
Verify that the malignancy is primary and located in the corpus uteri before assigning C54.
