Additional Info

  • Use this code for widespread or diffuse oral mucus membrane ulcerative lesions -- as may occur with chemotherapy, radiation
  • Do not use it for localized oral lesions or involvement in just a part of the oral mucosa. In such a case code the specific cause if known, and otherwise use Disorder of oral mucosa (mouth, lips, tongue), NOS.
