The “short-term” health plans the Trump administration is promoting as low-cost alternatives to Obamacare aren’t bound by the Affordable Care Act’s requirement to spend a substantial majority of their premium revenues on medical care. UnitedHealth is the largest seller of short-term plans, according to Axios, which provided this interesting detail on just how profitable this type of insurance can be: “United’s short-term plans paid out 44% of their premium revenues last year for medical care. ACA plans have to pay out at least 80%.”
