A POS health plan, short for Point-of-Service, is a type of health insurance that offers a mix of HMO (Health Maintenance Organization) and PPO (Preferred Provider Organization) features.
Like with an HMO, policyholders need to designate a primary care provider (PCP) and generally require referrals to see specialists. And like PPOs, POS plans allow out-of-network care. They are usually mid-level in terms of cost — cheaper than PPOs but more expensive than HMOs.
Selecting a POS plan involves weighing the inconvenience of needing referrals against the increased flexibility of out-of-network care.
