what are the differences between hmo ppo epo and pos?
With an HMO, your physician network is local. ... An EPO (or “exclusive provider organization”) is a bit like a hybrid of an HMO and a PPO. EPOs generally offer a little more flexibility than an HMO and are generally a bit less pricey than a PPO. Like a PPO, you do not need a referral to get care from a specialist.
