If you are coding a Pediatric Well visit 99392 and you also do a vision a 3yr old occular vision screen 99174, do you only apply the -59 on 99174?

If we are doing a Pediatric's Wll visit 99392 and we also do a 3yr old ocular vision screen 99174, do you only apply the -59 modifier? Has something changed and you also need to add the -25 modier to the 99392?
