I work for a hospitalist group and our physicians are contracted at a teaching hospital. We were only recently made aware of modifier GC. We have not been using this on our charges when supervising residents and we are getting paid with no issues. My question is, if we start using this, is it going to prompt an audit? Would we be ok to continue NOT using this modifier? We have been involved in audits in the past where we were required to send notes on these types of charges and there were no issues. We want to do what is right, but don't want to invite unnecessary attention. Thoughts?
