HealthCare.gov's definition: a POS plan charges less for in-network providers and requires a referral from your primary care doctor to see a specialist.
It is the hybrid: HMO-style primary care gatekeeping plus PPO-style out-of-network coverage at a higher price. The daily realities: nominate a primary doctor and go through them, never book a specialist without the referral, emergencies are covered anywhere, and in-network care is where the value sits. It suits people who want one doctor coordinating care and lower premiums than a PPO, with out-of-network as a backup rather than a habit.

What is a POS plan?
POS stands for point of service, and it is the hybrid of the plan alphabet. HealthCare.gov defines it: a type of plan where you pay less if you use doctors, hospitals, and other health care providers that belong to the plan's network, and POS plans require you to get a referral from your primary care doctor in order to see a specialist. That makes it a blend: HMO-style, you pick a primary care physician who gates specialist visits with referrals; PPO-style, you can go outside the network at a meaningfully higher cost. The practical consequences: nominate a primary care doctor and use them as your front door; a specialist visit without the referral can be denied or billed at out-of-network rates; emergencies are covered anywhere; and in-network care is where the value sits. Who it suits: people who like having one doctor quarterback their care, want lower premiums than a PPO, but want the theoretical option of out-of-network care that an HMO does not give. When comparing plans, check whether your current doctors are in-network and how referrals actually work, because the referral requirement is the daily-life difference you will feel most.
