Medicare Advantage Plan Types in South Carolina
Medicare Advantage plans in South Carolina come in several types:
- HMO (Health Maintenance Organization): Requires using in-network providers except in emergencies. Usually lower premiums. Often requires referrals to see specialists.
- PPO (Preferred Provider Organization): Allows out-of-network care at higher cost. No referrals needed for specialists. More flexibility but typically higher premiums.
- PFFS (Private Fee-for-Service): You can see any Medicare-approved provider that accepts the plan’s payment terms. Less common.

PPO plans are the most common type of Medicare Advantage plan in South Carolina.
