Code Description

ICD-10 C62.9 is a billable code used to indicate a diagnosis of malignant neoplasm of testis, unspecified whether descended or undescended.

Key Diagnostic Point:

C62.9 refers to a malignant neoplasm of the testis, where the specific type of testicular cancer is not specified as either descended or undescended. Testicular cancer is a relatively rare malignancy that primarily affects younger males, typically between the ages of 15 and 35. The most common types include seminomas and non-seminomas, which can arise from germ cells. Symptoms may include a painless lump in the testicle, swelling, or discomfort. Diagnosis is often confirmed through imaging studies such as ultrasound and serum tumor markers, including alpha-fetoprotein (AFP) and human chorionic gonadotropin (hCG). The staging of testicular cancer is crucial for determining treatment options and prognosis, with stages ranging from I (localized) to IV (metastatic). Fertility considerations are significant, as treatment may impact sperm production and quality. Patients are often counseled on sperm banking prior to treatment, especially if they are concerned about future fertility.

Code Complexity Analysis

Complexity Rating: Medium

Medium Complexity

Complexity Factors

  • Variability in tumor types and staging criteria
  • Need for precise documentation of clinical findings
  • Potential for misclassification of descended vs. undescended testis
  • Impact of treatment on fertility and need for pre-treatment counseling

Audit Risk Factors

  • Inadequate documentation of tumor type and staging
  • Failure to specify whether the testis is descended or undescended
  • Misalignment between clinical findings and coded diagnosis
  • Lack of documentation regarding fertility considerations

Specialty Focus
