Malignant neoplasm of endocervix

This code signifies the presence of a cancerous tumor originating in the glandular cells lining the endocervical canal, the inner part of the cervix. This malignancy is a type of cervical cancer that develops within the cervical opening leading to the uterus.

Assign this code when documentation clearly indicates a primary malignant neoplasm specifically located in the endocervix. This diagnosis is typically confirmed by biopsy and pathology reports identifying adenocarcinoma or other malignant cell types within the endocervical tissue.

• Differentiate from squamous cell carcinoma of the exocervix; this code is specific to the endocervical canal.
• Always confirm the primary site of the malignancy; do not use for metastatic disease to the endocervix.
• Ensure pathology reports explicitly state "endocervix" as the origin of the malignant neoplasm.
