What is a common feature of major medical insurance plans?

Major medical insurance plans are designed to provide comprehensive coverage for a wide range of medical expenses beyond what basic health insurance typically covers. They often include coverage for hospital stays, surgeries, and other significant medical services, which leads to substantial financial protection for insured individuals.

The reason that having a limit that applies to the entire treatment is a common feature of these plans is that major medical plans typically set an annual or lifetime maximum limit on benefits. This means that while these plans cover a significant portion of medical costs, there is a cap on how much they will pay for treatment over a specified period. This approach helps insurers manage risk and costs while still offering substantial coverage to policyholders for major health issues.

The other options do not accurately represent the characteristics of major medical insurance. Major medical plans certainly do not cover all expenses without limits, as they inherently have caps. They are not limited solely to catastrophic events; they are intended to cover a broader range of medical services. Additionally, major medical plans do often include coverage for outpatient services, contrary to the notion that they do not. Therefore, the presence of a limit that applies to the entire treatment aligns well with the concept of managing both individual health needs and overall insurance risk.
