What This Code Means

A cancerous tumor of the choroid (the blood vessel layer beneath the retina) when the specific eye is not identified.

Coding Tips

  • Query provider documentation if laterality is mentioned but not clearly specified in the diagnosis
  • Choroidal melanoma is the most common primary intraocular malignancy in adults

Clinical Significance

Choroidal melanoma is the most common primary intraocular malignancy in adults, arising from melanocytes in the uveal tract. It carries significant mortality risk due to hematogenous metastasis, particularly to the liver. This diagnosis drives substantial resource utilization including specialized imaging, radiation therapy (brachytherapy, proton beam), and long-term systemic surveillance.

Documentation Requirements

  • Pathology or characteristic clinical and imaging findings (ultrasonography showing dome-shaped or mushroom-shaped choroidal mass)
  • Laterality — query required if not documented since this is the unspecified code
  • Tumor dimensions (largest basal diameter and height)
  • AJCC staging for uveal melanoma
  • Liver imaging results for metastatic workup
