Please any other suggestions. Do I need to use both or something else?
Technically, if it was unplanned, the correct modifier is 78 - you may have to appeal with records if that's the case. But, if there was a possibility that the lens would need to be adjusted from the beginning (I'm not sure if that's a common thing or not - sorry) - then you might need to use modifier 58 - see the definition in appendix A for more info. 79 is definitely incorrect, so don't use that.
