Which type of plans does UHC not offer?

United Healthcare does not offer PFFS (Private Fee-for-Service) plans. PFFS plans are a type of Medicare Advantage plan that allows beneficiaries to see any doctor or use any hospital that accepts Medicare, without the need for a network. While UHC offers various Medicare Advantage options, they focus more on plans like PPO, HMO, and POS, which utilize network structures to manage care and costs.

The other options represent common types of managed care plans that United Healthcare actively provides. PPO plans are characterized by greater flexibility in choosing healthcare providers, HMO plans typically require members to select a primary care physician and get referrals for specialist care, and POS plans offer a combination of HMO and PPO features, allowing members to choose between in-network and out-of-network providers. Given UHC's portfolio and strategy, PFFS plans do not align with their approach to healthcare services compared to the other plan types mentioned.
