Code Description

ICD-10 C57.12 is a billable code used to indicate a diagnosis of malignant neoplasm of left broad ligament.

Key Diagnostic Point:

C57.12 refers to a malignant neoplasm located in the left broad ligament, which is a peritoneal fold that extends from the sides of the uterus to the pelvic walls. This type of cancer is classified under gynecologic malignancies and can arise from various cell types, including epithelial, stromal, or germ cell origins. The broad ligament supports the uterus and contains blood vessels, nerves, and lymphatics, making it a critical area for gynecological health. Symptoms may include pelvic pain, abnormal bleeding, or a palpable mass. Diagnosis typically involves imaging studies such as ultrasound or MRI, followed by biopsy for histological confirmation. Staging of the tumor is crucial for determining the extent of disease and guiding treatment, which may include surgery, chemotherapy, or radiation therapy. The CA-125 blood test may be utilized as a tumor marker, particularly in monitoring treatment response or recurrence. Accurate coding for C57.12 requires thorough documentation of the tumor's characteristics, staging, and treatment plan.

Code Complexity Analysis

Complexity Rating: Medium

Medium Complexity

Complexity Factors

  • Requires precise documentation of tumor location and type.
  • Staging information must be accurately captured.
  • Differentiation from benign conditions is necessary.
  • Potential for multiple treatment modalities complicates coding.

Audit Risk Factors

  • Inadequate documentation of tumor staging.
  • Failure to specify the laterality of the neoplasm.
  • Lack of supporting pathology reports.
  • Misclassification of tumor type or grade.

Frequently Asked Questions

What is the significance of CA-125 in relation to C57.12?

CA-125 is a tumor marker that can be elevated in cases of ovarian and related malignancies, including those affecting the broad ligament. It is often used to monitor treatment response and detect recurrence.
