Buyer beware: don't use Natera

Just got a bill from Natera today for $7551 for the Horizon test. I did the test in May and requested to pay directly. They quoted me $449 over the phone if I paid in 30 days. Instead of honoring this, they billed my insurance for $8000!!!!! I requested they revoke it and bill me the amount I was originally quoted. They obliged and I made the $449 payment last week. Just received a bill for $7551 to pay the amount they billed insurance.

Thieves just trying to steal every dollar they can from people at an extremely vulnerable time.
