2026 ICD-10-CM Diagnosis Code C57.02 – Malignant neoplasm of left fallopian tube
What it is
This code identifies a malignant tumor arising in the left fallopian tube. Use it when documentation specifically states primary cancer of the left tube.
Clinical signs
Clinical features vary; refer to documentation. Patients may have pelvic pain, abnormal vaginal bleeding, or a pelvic mass, but diagnosis is based on confirmed malignancy and site.
When to use this code
Use C57.02 when the provider documents primary malignant neoplasm of the left fallopian tube. It also applies when pathology or imaging supports left tubal origin and the left side is clearly specified. If laterality is unclear, check the record before coding.
Do not use for
Do not use this code for benign tubal tumors, metastatic disease to the fallopian tube, or cancer of an unspecified or different gynecologic site. Check documentation if the primary site is not clearly stated.
Coding tip
Verify laterality and primary site in the pathology or operative note before assigning C57.02.
