HMO and POS plans both require a primary care physician who coordinates your care and specialist referrals for in-network visits. The difference that actually changes your bills is out-of-network access. POS plans cover out-of-network care at higher cost. HMO plans cover emergency visits only when you leave the network, under federal law.
That out-of-network access gap changes your provider choices, your paperwork and your financial exposure when care falls outside your contracted network.
