Cancer that starts in the left fallopian tube, which is part of the female reproductive system that carries eggs from the ovary to the uterus.
Coding Tips
Clinical Significance
Malignant neoplasm of the left fallopian tube carries the same clinical significance as right-sided disease. Fallopian tube cancer is associated with hereditary breast-ovarian cancer syndrome (BRCA1/BRCA2 mutations), and prophylactic bilateral salpingectomy is now recommended for risk reduction even in average-risk women undergoing hysterectomy. Accurate laterality coding supports cancer surveillance and genetic counseling efforts.
Documentation Requirements
- ✓Laterality confirmed as left fallopian tube
- ✓Histological type and grade
- ✓FIGO staging
- ✓Pathological confirmation of tubal origin
- ✓Peritoneal involvement and cytology
- ✓BRCA and hereditary cancer panel results
- ✓Tumor markers (CA-125)
- ✓Surgical debulking status and residual disease assessment
Commonly Confused Codes
C57.01 — Right fallopian tube; laterality reversal errorC57.00 — Unspecified fallopian tube; use only when laterality is truly unknownC56.2 — Left ovary; distinguish tubal from ovarian primary siteC48.1 — Specified parts of peritoneum; primary peritoneal carcinoma is staged differently despite similar histology
