Costco does not accept insurance, BUT they helped me fill out the form and I filed on my own. My insurance pays $2500 once every 3 calendar years. In Ohio, there is no sales tax on medical appliances. So, my only out-of-pocket was the TV Connector.
Since the Costco hearing aid specialist is not a Dr, she could not write in the diagnosis code on my claim form. So, I looked up the code on the internet and entered it myself. It worked.
