* BlueCare: This prefix is used for HMO (Health Maintenance Organization) plans, which typically provide coverage for a specific network of healthcare providers. These plans often require referrals to see specialists and may not cover out-of-network care. * BlueChoice: This prefix is used for PPO (Preferred Provider Organization) plans, which offer more flexibility in choosing healthcare providers. These plans typically have a larger network of providers to choose from and may cover some out-of-network care. * BlueAdvantage: This prefix is used for POS (Point of Service) plans, which offer a combination of HMO and PPO features. These plans allow members to see out-of-network providers, but may require referrals and may have higher out-of-pocket costs. * BlueAccess: This prefix is used for EPO (Exclusive Provider Organization) plans, which are similar to HMO plans but do not require referrals to see specialists. These plans typically have a smaller network of providers than PPO plans. * BlueSolutions: This prefix is used for high-deductible health plans (HDHPs) that are designed to be used with health savings accounts (HSAs). These plans typically have lower monthly premiums but higher out-of-pocket costs. It is important to note that not all BCBS companies use the same prefixes, and some companies may use different prefixes to indicate the same type of coverage. Additionally, some BCBS companies may use additional prefixes or suffixes to indicate specific features or benefits of the plan, such as dental or vision coverage. * BlueCare: This prefix is used for HMO (Health Maintenance Organization) plans, which typically provide coverage for a specific network of healthcare providers.
