Challenging Anthem's Medical Necessity in Nevada

Nevada's external review process provides an independent physician review that overrides Anthem's internal IndiGO determination. When building your appeal, focus on the specific Clinical Policy Bulletin criteria Anthem applied. Obtain the bulletin, identify where your claim allegedly fails the criteria, and build a clinical argument — backed by your physician and peer-reviewed guidelines — showing either that your case satisfies the criteria or that the criteria conflict with current medical standards. For mental health denials in Nevada, invoke the state parity law alongside MHPAEA for maximum regulatory pressure.
