Short term medical plans are temporary insurance options, not long-term health insurance needs. The monthly premium cost may be lower because these plans do not offer as many benefits and are not subject to ACA requirements. For example, they provide less coverage, like comprehensive preventive care benefits. STM plans are designed to provide limited benefits to help with medical treatments resulting from unexpected illnesses and injuries.
