I would think the body would heal when it gets warm or medical technology is advanced enough to allow some healing.

Frostbite means your tissue is freezing, and ice at a microscopic level in that sense is like a bunch of sharp points which can tear stuff up, on top of that it stops getting oxygen and now you have something that is attached to you that is literally dead, and once tissue dies there isn’t really a way to make it come back, so you’re only left with cutting it off and hoping nothing leeched into your circulatory system from the dead tissue
