State Insurance Commissioner Mike Chaney is willing to sue the federal Centers for Medicare and Medicaid Services if it does not allow Mississippi to create a state-based health insurance exchange because of Republican Gov. Tate Reeves’ potential opposition. Federal officials, who must approve of a state implementing its own health insurance exchange, want a letter of approval from a state’s governor before they allow a state to implement the program, according to Chaney.   “I don’t know what the governor’s going to do,” Chaney told Mississippi Today. “I think he’ll probably wait until after the election to make a decision. But I’m willing to sue CMS if that’s what it takes.”  The five-term commissioner, a Republican, said his requests to Reeves, also a Republican, to discuss the policy have gone unanswered. The governor’s office did not respond to a request to comment on this story.  Earlier this year, the Legislature passed a law authorizing Chaney’s agency to create a Mississippi-based exchange to replace the federal exchange that currently is used by Mississippians to obtain health insurance. The bill became law without the governor’s signature. States that operate their own exchanges can typically attract more companies to write health insurance policies and offer people policies at lower costs, and it would likely save the state millions of dollars in payments to the federal government. Chaney also said he’s been consulting with former Republican Gov. Haley Barbour, who also supported some version of a state-based exchange while in office, about implementing a state-based program.  Currently, 21 states plus the District of Columbia have state-based exchanges, though three still operate from the federal platform. Should he follow through and sue the federal government, Chaney said he would use outside counsel and several other states told him they would join the lawsuit.
