A Point-of-Service (POS) plan combines features of an HMO and a PPO. Like an HMO, you choose a primary care physician who coordinates your care and provides referrals. Like a PPO, you have the option to see out-of-network providers — though at a significantly higher cost share.
How a POS plan works in practice:
POS plans are less common on the ACA Marketplace than HMOs, PPOs, and EPOs. When available, they offer a middle ground: more provider flexibility than an HMO with more structure than a PPO. The premium typically falls between the two.
A POS requires a PCP and referrals, like an HMO. An EPO also restricts you to the network but does not require a PCP or referrals. If network access matters and you want direct specialist access without referrals, an EPO is more flexible. If you want the option to occasionally go out-of-network with a referral, a POS provides that while still offering in-network cost control.
On a POS plan, you can see out-of-network providers, but you’ll typically need a referral from your PCP first, and you’ll pay significantly more — higher coinsurance, a separate out-of-network deductible, and possibly a higher out-of-pocket maximum. Without a referral for out-of-network care, coverage may be denied entirely depending on the plan.
