What is a Point-Of-Service (POS) plan primarily characterized by?

A Point-Of-Service (POS) plan is primarily characterized as a combination of Health Maintenance Organization (HMO) and Preferred Provider Organization (PPO) plans. This hybrid structure allows members to choose how they want to receive care. Like an HMO, a POS plan requires members to choose a primary care physician (PCP) who will coordinate their healthcare. The PCP can provide referrals to specialists, and accessing in-network care usually results in lower out-of-pocket costs.

At the same time, POS plans also offer some of the flexibility that a PPO provides. If members decide to seek care outside of their network, they still have the option to do so but will typically incur higher costs, mirroring the PPO's structure. This combination is particularly appealing for individuals who want the cost control benefits of an HMO while also having the flexibility to go out of network when necessary.
