Treatment requests are classified into broad categories and subcategories; specific detail is found in the Final Determination Letter.

  • Uphold – the IMRO decided that the disputed service was not medically necessary and appropriate.
  • Overturn – the IMRO decided that the disputed service is medically necessary and appropriate.
