we just, we're just moving into the 2022 code sets for I-10. So that's a yearly change and sometimes they are greater, the changes are greater than other years. Yes. And even bigger changes like I-9 to I-10. Yes. Yes. And even bigger changes like I 9 to I 10. Yes, that was a big one. So on. Yeah. What are some memorable changes in the revenue cycle through your career that really shook up the industry and your work? The, well, definitely the change for my nine to I-chin because when I was at that coding company, we hired a new coder and we put her on mammograms, which was a very straightforward thing. And she started getting all these denials. And we're thinking, how could this be? So we went in and audited her and it goes back to reading again. She was coding cystic fibrosis for fibrocystic breast disease. So you don't get a mammogram for cystic fibrosis. But those people who haven't played with I know I don't remember that change very well. Other than that, I see the the Max coming in, the RAC auditors, the more and more emphasis on being aware that, you know, there are consequences to what you do. You know, if you make a coding error, they'll forgive you. If you continue the error, they'll say, hey, you need some education. But if you continue the error, then they're going to measure you for a jumpsuit. Oh, boy. Well, that's interesting to hear all of these different changes and the impacts that they've had. It really is. And, you know, it's frustrating sometimes. For instance, my hospital that I do, most of my work for
