Illinois has no DPC laws at present and none are known to be planned in this current legislative session.  DPC practices are already operational within the state.  Be sure to review the Illinois Insurance Code when planning your DPC practice.  Thanks to the efforts of the Illinois AFP (in their letter dated 03/30/18) the Illinois Department of Insurance (in their letter dated 04/16/18) appears to agree that physicians operating DPC practices are not in the business of insurance.
