Am I Eligible for Septoplasty? I Have 30% Deviated Septum.

I went to an ENT for a deviated septum, I was told my left side was deviated by 30 percent, I have breathing problems through my nose he prescribed me omnaris. I asked about septoplasty he said maybe later in time, my question would be is having 30 percent deviated septum a reason for my insurance bcbsil to approve the surgery??
