Code Description

ICD-10 C79.6 is a billable code used to indicate a diagnosis of secondary malignant neoplasm of ovary.

Key Diagnostic Point:

C79.6 refers to secondary malignant neoplasms of the ovary, indicating that the cancer has metastasized to the ovarian tissue from a primary site elsewhere in the body. This condition is often associated with advanced stages of cancer, where the primary tumor may be unknown or previously diagnosed. Common primary sites include breast, colon, and gastrointestinal cancers. The clinical presentation may vary, but symptoms can include abdominal pain, bloating, and changes in menstrual cycles. Diagnosis typically involves imaging studies such as ultrasound, CT scans, or MRI, alongside histopathological examination of ovarian tissue. Staging of metastatic ovarian cancer is crucial for treatment planning and prognosis, often classified using the FIGO system. Palliative care considerations are essential, focusing on symptom management and quality of life, especially in cases where curative treatment is not feasible. Understanding the metastatic nature of this condition is vital for appropriate coding and treatment pathways.

Code Complexity Analysis

Complexity Rating: High

High Complexity

Complexity Factors

  • Determining the primary site of cancer can be challenging.
  • Need for accurate staging information.
  • Differentiating between primary ovarian cancer and secondary neoplasms.
  • Documentation of metastatic disease requires comprehensive clinical details.

Audit Risk Factors

  • Inadequate documentation of the primary cancer site.
  • Failure to document staging information.
  • Misclassification of primary versus secondary neoplasms.
  • Lack of clarity in treatment intent (curative vs. palliative).
