You’ll Never Guess Which Company Is Reinventing Health Benefits

It’s hard to think of a company that seems less likely to transform health care.

It isn’t headquartered in Silicon Valley, with all the venture-backed start-ups. It’s not among the corporate giants — Amazon, Berkshire Hathaway and JPMorgan Chase — that recently announced, with much fanfare, a plan to overhaul the medical-industrial complex for their employees.

And it is among the most hated companies in the United States, according to many surveys on customer satisfaction.

It’s Comcast. The nation’s largest cable company — the $169 billionPhiladelphia-based behemoth that also controls Universal Parks & Resorts, “Sunday Night Football” and MSNBC — is among a handful of employers declaring progress in reaching a much-desired goal. In the last five years, the company says, its health care costs have stayed nearly flat. They are increasing by about 1 percent a year, well under the 3 percent average of other large employers and below general inflation.
