Regulators in Colorado received similar complaints, and forced Humana to issue an apology and a corrected letter that met state standards. And in Missouri, regulators are investigating similar complaints. What about other states? Sounds to me like a good tip for further investigation.

One thing missing from Scott’s story was a bit of Humana’s past. The company has a history of aggressive marketing tactics relating to Medicare HMOs and, later, Medicare drug benefits. It got into hot water with regulators and made amends, all the while amassing huge market share that transformed the company into one of the nation’s largest health insurers. A bit of this backstory would add more context to the current events.

That aside, Scott’s article shows it’s possible to break through the insurance industry’s formidable wall of silence. Even if insurers continue to circle the wagons, there’s plenty on the public record that provides an entry point to understanding what the game is all about—competition and market share.
