We are having an issue with 93010 being denied as "billed by a different provider", but the provider isn't one of ours. We have only billed 93010 once. Can I just slap a modifier 77 on there and assume a different doctor with a different service billed for this interp also? Is modifier 77 appropriate if we have only billed for one? Thanks!
