I had a botched septoplasty 40+ years ago from a EENT doctor, who removed much cartilage. Cannot breathe through nose?

I had a botched septoplasty 40 plus years ago from a EENT doctor, who removed much cartilage. Since then my nose has closed up on both sides so I cannot breathe through my nose. I am a mouth breather and have sleep apnea. I want to have my breathing improved because I have frequent headaches. Does insurance HIC and Medicare pay any of these costs. I am in constant distress from not breathing correctly.
