Malignant neoplasm of fallopian tube

This code signifies the presence of a cancerous tumor originating in the fallopian tube, which are the ducts that transport ova from the ovary to the uterus. This is a rare gynecologic malignancy that can be primary or metastatic.

Use this code when documentation confirms a primary malignant neoplasm of the fallopian tube. This diagnosis is typically established through biopsy and histopathological examination. It should be used for initial diagnosis and subsequent treatment encounters related to this specific cancer.

• Differentiate between primary fallopian tube cancer and metastatic disease to the fallopian tube; this code is for primary only.
• Ensure documentation specifies "malignant" to avoid confusion with benign or uncertain neoplasms.
• Consider sequencing with codes for any associated symptoms or complications, such as ascites or pain.
