Bisalp not covered by BCBSTX

I had a consultation for a Bilateral Salpingectomy earlier this week, and was given the go ahead to schedule the surgery.

The total would be $3000+. When I mentioned that I thought the procedure would be covered under insurance, the surgery scheduler at my doctor’s office said “We do not code it as preventative, so it will not be covered”.

Any advice on how to proceed from here? Do I call BCBS and try to get someone to confirm that it will be covered?

For extra information: I do have BCBS HMO through my employer.
