Anything can be repaired. Its a matter of cost vs replacement. You didn't state what lens broke, just the front glass or is there other damage. I have some lenses that are expensive and others that are discontinued. If they were damaged I would highly consider having them repaired. I don't know your equipment, but all mine are insured. If you have a lot of gear that is something you may want to consider for the future. Here is an example, I broke one of my external flashes. The replacement cost is $225. When I send it in, if the repair estimate is less than that in any substantial way it will be repaired. If its totaled, then I will probably claim it on the insurance and get a new one.
