Insurance coverage for fixing broken nose?

About 5 months ago I got hit on the face with a basketball. The doctor said my nose looked crooked but not broken and she said i should be fine and that any breathing problems are from it swelling. Currently I generally can not breathe out my left nostril but when I am able to, my right nostril feels clogged up. At times it is hard to breathe and my nose just feels stuffy. When I touch the bump on my nose it still sounds like its cracking but not as loud as when the accident occurred.
