Which two healthcare plans typically require patients to see a primary care physician?

POS: POS stands for "Point of Service." POS plans combine elements of both HMO and PPO plans. As a member of a POS plan, you may be required to choose a primary care physician who will then make referrals to specialists in the health insurance company's network of preferred providers. Care rendered by non-network providers will typically cost you more out of pocket, and may not be covered at all.
