This isn't new news, but in early May, four individuals were convicted in federal court of either leaking or using confidential CMS policy information prior to its release, with resulting financial gains.
The convictions were announced for David Blaszczak, a policy consultant, Christopher Worrall, a then-current CMS employee, and two staff at Deerfield Management hedge fund, Theodore Huber and Robert Olan.

During the trial, Bloomberg had run an article about the strongly conveyed testimony of former CMS deputy director Jonathan Blum, on how stringently he tried to convey confidentiality rules (here).
