Is it possible to fix the glass side panel of iPhone 5S?

I dropped it and now have nasty marks on the glass side of it. What's that part called? The circled one in the pic? And can I fix it/replace it? Don't want a new phone as that one is pretty new, Apple won't replace it cause of the scratches, right? Would appreciate answers if anyone knows. Cheers.

That's not glass. That's stainless steel. As far as them replacing it, I doubt, not necessarily cause of the scratches though. I suggest you check with a phone repair shop about it.
