A Point-of-Service (POS) health plan is best described as:

Why A is correct

A POS plan blends HMO and PPO features: members select a primary care physician who acts as a gatekeeper for referrals, yet members may go outside the network at the point of service and receive care at a higher cost share. Care coordinated within the network is covered more generously, while out-of-network care involves higher deductibles or coinsurance. The California A&H objectives list POS among the group care-plan delivery models (HMO, POS, PPO, EPO).

Why the other options are wrong

• B) POS refers to a managed care delivery model with in-network and out-of-network tiers, not to employer on-site clinics.
• C) A POS plan has a network and a gatekeeper; pure fee-for-service plans have no managed network at all.
• D) The defining feature of POS is that it does allow out-of-network care at the point of service, unlike a pure HMO or EPO.

Memory hook

POS = pick a gatekeeper, but the door to out-of-network stays open; you just pay more to walk through it.

Why A is correct

A POS plan is a hybrid managed care product. In-network, it works like an HMO: the member selects a primary care physician, and in-network care requires a referral or is coordinated through the plan. However, unlike a pure HMO, a POS plan permits members to go outside the network for care, usually paying higher deductibles, coinsurance, or copayments and often without the same level of plan coordination. The decision is made at the point of service, which is where the plan gets its name. This flexibility is the key feature that distinguishes a POS plan from a standard HMO.

Why the other options are wrong

• B) A POS plan does have a network and a primary care structure; a plan with no network that pays any charge is a traditional indemnity or fee-for-service plan.
• C) POS plans cover the full range of medical services, not only emergency hospital care.
• D) Premium payment is a policy funding condition, not a defining feature of any plan type, and POS plans do not operate that way.

Memory hook

POS = HMO gatekeeping inside, out-of-network option outside, chosen at the point of service.
