Do I need a special medical visa to travel to Korea for work?

Maybe I am looking in the wrong places but I can't seem to find an answer on this. I asked on another forum and reddit but no one replied. I am hoping to get some answers here. I watched a video that mentioned a medical visa but I am not sure if that is something I need or not. I am in the United States FIY. Not sure if the surgery matters or not.

EDIT: for clarification, "for work" means plastic surgery. I don't want to be misunderstood given the standard nature of visas.

This is actually a good question. As far as I know, you do not need one. I believe the standard travel laws (through a passport) allow for up to a 90 day stay. So You could realistically go there for 3 months and get tons of work done and have time for it. I don't think any western nation requires a special visa.
