Which of the following statements is true regarding HMO insurance plans?

The statement that pertains to HMO (Health Maintenance Organization) insurance plans indicates that they often have lower premiums and out-of-pocket costs. This is true because HMO plans typically utilize a network of doctors and hospitals which allows them to negotiate lower rates. The cost-sharing structure in HMO plans tends to favor lower copayments and deductibles, making them generally more affordable for enrollees compared to plans that allow broader flexibility, such as PPOs (Preferred Provider Organizations).

In HMO plans, the focus on preventative care and the requirement for members to choose a primary care physician who coordinates their care generally helps reduce overall health care spending. This managed care approach helps keep costs down, translating into the lower premiums and out-of-pocket expenses noted in the correct statement.

In contrast, the other options reflect characteristics that are not typical of HMO plans. They often do not cover any physician regardless of network status, usually require referrals for specialty care, and involve the necessity of having a primary care physician to manage medical needs.
