Does Humana PPO require a referral to see a specialist?

Unlike an HMO, a PPO offers you the freedom to receive care from any provider—in or out of your network. This means you can see any doctor or specialist, or use any hospital. In addition, PPO plans do not require you to choose a primary care physician (PCP) and do not require referrals. Oct 1, 2017
