Mayo Rochester (affectionately known as the Mother Ship) is the leading center of excellence for septal myectomy. World wide leader.
I would heed the advice of @walkinggirl and "RUN" to check if your insurance is accepted at Mayo Rochester. I know Medicare is, and many advantage plans as well.

This is not something you want to trust to just any hospital, as you now know.
I encourage you to put yourself first in this case, and be your own best advocate. You need the best surgeons for this surgery. This should not be about location or convenience. It's your life and future.
Please read the response you got from @dbrima. She has been through an emotional war and came through...not without scars for sure. From actually getting worse on Camzyos to a failed septal myectomy in Texas to ending up at Mayo Rochester...she knows for certain how important it is to have this procedure performed by experts. Experts who do many not just a few!
I cannot emphasize enough... you need a COE Center of Excellence for a septal myectomy. Period.
