Indiana prior authorization resources

Humana Healthy Horizons® in Indiana members may see any participating network provider, including specialists, and receive services at inpatient hospitals. Humana Healthy Horizons does not require referrals from primary care providers to see participating specialists; however, prior authorization must be obtained to see nonparticipating providers in most situations (please review the provider manual for a few exceptions).
