UnitedHealthcare sells 492 Medicare Advantage plans in four types that differ on network rules and referrals. HMO-POS (305 plans) and PPO (179) make up 484 of them, and every state UnitedHealthcare serves, plus Washington, D.C., has one or both.
- HMO (Health Maintenance Organization): Stay in the plan's network except in emergencies, with a primary care doctor's referral for specialists. Five UnitedHealthcare plans, all in Florida, with a $3,233 average MOOP that's $2,426 below UnitedHealthcare's HMO-POS average.
- HMO-POS (HMO with Point-of-Service): Works like an HMO but also covers some out-of-network care at a higher cost. UnitedHealthcare's most common type, with 305 plans in 40 states, and the main network option for buyers outside Florida.
- PPO (Preferred Provider Organization): See in-network or out-of-network doctors without a referral, though out-of-network care costs more. 179 UnitedHealthcare plans in 44 states and Washington, D.C. They average $37 a month, $22 more than HMO-POS, and suit buyers who keep out-of-network doctors.
- PFFS (Private Fee-for-Service): See any Medicare-approved doctor or hospital that accepts the plan's payment terms, with no referrals. Three UnitedHealthcare plans, one each in Kansas, Montana and Wyoming. They average $118 a month, $81 more than UnitedHealthcare's PPO average, and PPO plans are also sold in all three states.
