Malignant neoplasm of exocervix

This code signifies a cancerous tumor originating from the outer portion of the cervix, which is covered by squamous epithelial cells. It represents a primary malignancy of the exocervix, distinct from tumors arising in the endocervix.

Apply this code when documentation clearly specifies a malignant neoplasm located on the exocervix. This is typically supported by pathology reports confirming squamous cell carcinoma or adenocarcinoma originating from the ectocervix.

• Differentiate carefully between exocervical and endocervical involvement; the site specificity is crucial for accurate coding.
• Ensure the pathology report confirms malignancy and the specific cervical location.
• Sequence this code as the primary diagnosis when the exocervical malignancy is the reason for the encounter.
