Lasso Healthcare Insurance Co., which offers a novel implementation of the Medical Savings Account (MSA) concept in the Medicare Advantage market, has been acquired by Zing Health Enterprises, a Chicago-based physician-founded and managed provider of Medicare Advantage health insurance. “We look to offer greater financial control to those insured and provide an alternative to seniors that is comparable to the growing popularity of high-deductible health plans,” said Craig Ritter, CEO of Lasso Healthcare.
