Malignant neoplasm of exocervix

This code identifies a primary cancerous tumor originating in the exocervix, the outer portion of the cervix that projects into the vagina. This malignancy typically arises from squamous cells and is often associated with human papillomavirus (HPV) infection.

Apply this code when documentation confirms a primary malignant neoplasm specifically located in the exocervix. This diagnosis is typically established through biopsy and histopathological examination. Use for initial encounters, active treatment, or surveillance of this specific cancer site.

• Ensure documentation specifies "exocervix" rather than "endocervix" or "cervix, unspecified."
• Code any associated HPV infection separately if documented and clinically relevant.
• Properly sequence this code based on the reason for the encounter (e.g., primary diagnosis for cancer treatment, secondary for complications).
