Hospital Insurance Flex: What Does It Mean?

1. What is a hospital Flex insurance?

A hospital Flex insurance is a hospital supplementary insurance that usually is based on the general ward and allows an upgrade to semi-private or private at hospital entry. It counts among the cheapest level of supplementary insurance in the hospital area.

The term comes from the flexible choice: Flex insured persons decide only at the inpatient stay about the hospital ward. Without upgrade, the basic insurance of Swiss insurers applies with multi-bed room in the general ward. With upgrade to semi-private or private, an own share applies.

At conclusion, the insurer examines the health condition. The health questionnaire decides on admission and conditions. With existing illnesses, policy restrictions or rejection are possible.

2. Which benefits does the Flex insurance cover?

The benefits of a Flex insurance differ between insurer and tariff. Usually, you are insured in the general ward of your canton of residence hospital without additional costs. At hospital entry, you decide on an upgrade to semi-private with twin room or private with single room.

With upgrade, Switzerland-wide hospital choice (provided a tariff contract with the insurer exists), free choice of doctor with treatment by senior physician or chief physician, and rooming-in with the child take effect. Some tariffs additionally limit the cumulated own share per family.
