Code Description

ICD-10 C57.01 is a billable code used to indicate a diagnosis of malignant neoplasm of right fallopian tube.

Key Diagnostic Point:

Malignant neoplasm of the right fallopian tube is a rare gynecologic malignancy that arises from the epithelial cells lining the fallopian tube. This condition is often asymptomatic in its early stages, leading to late diagnosis when the tumor may have already spread to adjacent structures or metastasized. Symptoms may include abdominal pain, abnormal vaginal bleeding, and pelvic mass. Diagnosis typically involves imaging studies such as ultrasound or CT scans, and confirmation is achieved through histopathological examination following surgical intervention. The staging of fallopian tube cancer is crucial for determining treatment options and prognosis, with the FIGO staging system commonly used. Treatment often involves a combination of surgery, which may include salpingo-oophorectomy, and adjuvant chemotherapy. The tumor marker CA-125 is frequently elevated in patients with fallopian tube malignancies and can be used for monitoring treatment response and disease recurrence.

Code Complexity Analysis

Complexity Rating: Medium

Medium Complexity

Complexity Factors

  • Rarity of the condition leading to potential misdiagnosis.
  • Need for precise staging and documentation of tumor size and spread.
  • Variability in clinical presentation and symptoms.
  • Potential for concurrent gynecologic malignancies.

Audit Risk Factors

  • Inadequate documentation of staging and tumor characteristics.
  • Failure to link the diagnosis with appropriate surgical procedures.
  • Misinterpretation of pathology reports.
  • Inconsistent use of CA-125 levels in treatment monitoring.
