  • Whether a specialist referral requires prior authorization<\/span><\/li>
  • Which hospitals are in-network (and therefore cheaper for you)<\/span><\/li>
  • Whether a procedure is ‘medically necessary’ \u2014 or denied<\/span><\/li>
  • How your care is managed if you have a chronic condition<\/span><\/li><\/ul>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t
