These define how care is delivered and can apply to both public (e.g., Medicare Advantage) and private plans:
Health Maintenance Organization (HMO)- Details: Requires a primary care physician (PCP) for referrals to specialists. Covers only in-network providers, except emergencies. Focuses on preventive care.
- Pros: Lower costs, coordinated care.
- Cons: Limited provider choice.
Preferred Provider Organization (PPO)- Details: Wider network; no referral needed for specialists. Covers out-of-network care at a higher cost.
- Pros: More flexibility.
- Cons: Higher premiums and out-of-pocket costs.
Exclusive Provider Organization (EPO)- Details: In-network only (except emergencies), but no PCP referral required.
- Pros: Balances cost and flexibility.
- Cons: No out-of-network coverage.
Point of Service (POS)- Details: Hybrid of HMO and PPO. Requires a PCP but allows out-of-network care at higher costs.
- Pros: Some flexibility with oversight.
- Cons: Referral paperwork and higher out-of-network costs.
