Although designed to help employers by routing their workers to higher-quality, lower-cost health care providers, Uber Health’s latest partnership may expose the companies to certain risks and liabilities, legal experts said.

Last week, the ride-hailing giant’s growing health arm announced it has teamed up with health tech startup Grand Rounds, which works with large, self-insured employers to provide employees with a platform that helps them with everything from getting a second opinion to scheduling appointments with appropriate physicians. Now that also includes employees’ Uber rides to medical appointments at the expense of the employers and their health plans.
