- Strict in-network coverage
Preferred Provider Organization (PPO) Out-of-network providers allowed, but cost more. - Tends to be more expensive
- No referrals necessary (OON)
Exclusive Provider Organization (EPO) Restricted to a limited panel of physicians - Similar to HMOs, but network tends to be smaller
Point of Service (POS) Out-of-network providers allowed, but designated "in network" to reduce costs. - Requires referrals from PCP (OON)

Health care payment models


Payment Model Description Provider Risk Patient Experience Examples/Usage
Fee-for-service Payment made for each individual service provided Low risk for providers; incentivizes volume of services May lead to unnecessary services; less coordination of care Traditional insurance model; Medicare Part B
Discounted fee-for-service Payment for each individual service at a discounted rate pre-determined between providers and payers Moderate provider risk due to discounted rates Similar to fee-for-service but with potentially lower copays PPOs commonly use this model
Global payment Single payment covers all expenses for a specific episode of care Higher risk for providers if complications arise Simpler billing; transparent total cost Common for elective surgeries including pre- and post-operative care
Bundled payment Set payment amount for a service to be divided among all involved providers/facilities High risk for providers if costs exceed the bundle amount Potentially better care coordination across providers Joint replacements, cardiac procedures, maternity care
Capitation Fixed payment per patient per time period regardless of services used Highest risk for providers; may limit unnecessary care May improve preventive care; potential for undertreatment Common in HMOs; Primary care capitation models
