Steph,
I'm not sure if this will help you or not, but Athena, the lab that does the MUSK testing has a patient protection plan. I used it when I had the MUSK testing done. It significantly limited the cost I incurred for the testing. My insurance plan did not contract with Athena.

I'll try to post the link here, but if it doesn't come through just google Athena and patient protection plan. Hope this helps.
