SIOUX FALLS, S.D. -

Avera Health facilities and physicians in South Dakota won't accept insurance plans offered by Sanford Health starting Jan. 1.
    
Avera announced the decision Friday.
    
Aside from medical services, both health systems offer insurance plans. Avera's move comes after Sanford announced this summer that its physicians and facilities would stop accepting Avera's insurance plans.
    
Some exceptions will apply to Avera's change, including situations when women are in their second or third trimester of pregnancy, or people who are under complex care plans like those for cancer treatment.
    
Avera on Friday acknowledged that Sanford's decision was the "catalyst for Avera to reconsider the same for participation in their network."
    
Dr. Tad Jacobs is the chief medical officer for Avera Medical Group. He says the decision will make Avera's system "stronger."
