Considered out of network for my insurance. I've had better luck just using FSA funds to pay for whatever I need from
Defy. They're super cool about providing letters of medical necessity. Besides receipts, that's all I've had to supply to get FSA to "approve" the expense.
On the other hand...
My health insurance covers labs at 100%. I have the list and take it to my primary care physician. He orders the labs for me and I have the blood work done at a local Labcorp. BAM! Covered in full and never receive a bill for it.
