Code Description

ICD-10 C79.82 is a billable code used to indicate a diagnosis of secondary malignant neoplasm of genital organs.

Key Diagnostic Point:

C79.82 refers to secondary malignant neoplasms that have metastasized to the genital organs from a primary site elsewhere in the body. This condition indicates that cancer cells have spread to the genital organs, which may include the ovaries, uterus, vagina, penis, or testicles. The primary tumor may be of unknown origin, complicating diagnosis and treatment. Metastatic disease in the genital organs can lead to various symptoms, including pain, abnormal bleeding, and changes in urinary or sexual function. Staging of the disease is crucial for determining the extent of metastasis and guiding treatment options. Palliative care considerations are essential for managing symptoms and improving the quality of life for patients with advanced disease. Treatment may involve chemotherapy, radiation therapy, or surgical interventions, depending on the primary cancer type and the extent of metastasis. Accurate coding is vital for appropriate reimbursement and tracking of cancer treatment outcomes.

Complexity Factors

  • Determining the primary site of cancer when it is unknown.
  • Differentiating between primary and secondary malignancies.
  • Staging considerations that may vary based on the primary cancer type.
  • Documentation requirements for metastatic disease.

Audit Risk Factors

  • Inadequate documentation of the primary cancer site.
  • Failure to document staging information.
  • Misclassification of primary versus secondary malignancies.
  • Lack of clarity in treatment plans related to palliative care.
