Have you called your insurer?

Your’s sounds the highest I’ve heard. I wonder if you can negotiate down.

Medicare Advantage is basically private insurance. You get some extra goodies like gym memberships but you are still at the mercy of private insurance.

My straight Medicare with a covid test in April left a balance of $110 which was sent on to my secondary insurance (a private insurance company from my previous employer, a retirement benefit) and either they paid the whole thing or there was only a little left over for me to pay.

Interestingly the test was billed to Medicare at $7761.00 (!) and Medicare Approved $547.77 and paid $439.93.

Frankly, the feds should be making tests free to anyone who wants it and testing materials and labs ramped up like we were on a war footing. And don't get me started on contact tracing.
