Not sure if we can truly help, I have two insurance providers and their lists are different. Even though I never uses my insurance benefits on semi-legit massages, I still monitor the lists. I think the only thing you can do is to read the reviews here and cross reference to providers listed on your specific list. The problem is that some of the providers on the lists are individuals (not spas) with their real names listed, this is actually the case of my former legit masseuse, she direct bills my insurance under her personal name and not the spa. We (and I stress) should never disclose a provider's real name here. Finally, of all of the places I visited, whether I need insurance receipt and which insurance provider is always among the first question asked by the spa, if you are wondering, just ask them; if they can't provide a receipt for your insurance provider, a reputable spa will always tell you. If anyone does provide you with a bogus receipt, that, you should share here so the rest of us can learn and thank you for toftt. My two cents only.
