Where To File A Complaint Against A Health Insurance Company? 
All insurance companies are regulated on a state level . The first place to complain would be with the Department of Insurance of the state in which you reside . If your health coverage was purchased on either a state or federal insurance exchange -LRB- i.e. an `` Obamacare plan '' -RRB- , you may also file a complaint directly with the exchange . I would also suggest you speak with an independent insurance agent that represents the company to see if they can be of any assistance in resolving your concerns , or helping you change plans .
