What acronyms does not represent a managed care plan?

Acronyms that do not represent a managed care plan include FFS (Fee-for-Service), which is a payment model where providers are paid for each service rendered. Another example is PPO (Preferred Provider Organization), which is a type of managed care but operates differently from stricter models like HMO (Health Maintenance Organization). Additionally, terms like EAP (Employee Assistance Program) are related to employee benefits but do not represent managed care plans.
