What you're probably seeing are the bills that your service provider sends to insurance, and then your insurance sending you a statement of benefits.
If these were real bills, they would keep sending them.
(Sometimes these can be amusing: I had surgery in 2011, and the hospital billed the insurance company $100,000. The insurance company responded that the agreed cost for services should be $20,000. The hospital ended up getting $20,000. IMO, $20,000 was plenty to pay everyone involved.)
