Medicare pays 80% of my IVIG treatments, and my secondary insurance pays the balance.

The amounts I listed are the 'billed' amounts on my insurance statements. The insurance actually pays less, because they have a contract with the provider. Patients paying out of pocket don't get to benefit from those contracted amounts, so usually have to pay full price. I'm sure there may be 'some' negotiating that can happen, but it's not going to bring it down into a reasonable rate for the average person.

If you have a positive skin biopsy, then maybe your insurance will cover the cost...at least some.
