The Justice Department filed a complaint alleging some of the biggest Medicare insurers paid kickbacks to brokers that sell such plans, seeking to grab market share and in some cases avoid enrollees with disabilities who might come with heavy health costs.

The complaint names units of CVS Health, Elevance Health and Humana, along with broker companies eHealth, GoHealth, and SelectQuote.

The Justice Department has sued three of the largest Medicare Advantage insurers and three dominant insurance brokerages, alleging a kickbacks scheme.
