Short term health plans generally have more affordable premiums than major medical plans because they are not subject to ACA provisions and provide less coverage. For example, short- term medical insurance has few or no preventive care benefits.

Short term health insurance plans are designed to provide benefits that help with medical bills resulting from unexpected illnesses and injuries.

In general, the more coverage you seek, whether through an ACA plan or a short term plan, the higher the premium you will pay.
