Prior authorization resources

Humana Healthy Horizons™ in Ohio members may see any participating network provider, including specialists and inpatient hospitals. Humana Healthy Horizons in Ohio does not require referrals from primary care providers (PCPs) to see participating specialists; however, prior authorization must be obtained to see nonparticipating providers. Members may self-refer to any participating provider. PCPs do not need to arrange or approve these services for members, as long as applicable benefit limits have not been exhausted.
