So, as you review these elements and the criteria to meet each one, I think it's easy to apply baseline knowledge of what you already know and let’s use this as an example for a more direct approach. If you've decided to bill time based, for example for low vision, you can go ahead and we’ll direct you to those guidelines and that criteria that’s necessary to meet. Historically, you've already billed something as a level five, you'll probably continue to do so as it pertains to life threatening conditions, such as a brain tumor, blindness or death. This is still going to be billed very rarely at your office. Some examples of this would be a retinal artery occlusion or orbital cellulitis as you referred to Dr. Cockrell. We've defined self-limiting or minor problems as something that will likely resolve on its own and have very little to no documentation and without risk. If you have one problem, and it stays on one, this could meet the requirements for a level two and also per our previous definition provided, if an independent historian is required you’re probably deciding either between a level three or level four and depending on problems addressed and risk will be the deciding factor. If you have a type of referral from another office to yours you're going to do some interprofessional consultation or you're doing some type of reviewing of external tests. You will meet the criteria for either a level three or level four. Again, looking at problems addressed and risk for your final determining factors for that level. So Dr. Cockrell, I think it's important you know, let's make this as simple as possible. Taking some of these cases that you're familiar with and utilizing guidelines in years past and how you can take that information and easily apply it. And so now, it's really just about differentiating a level three and a level four and sometimes a level five in your office and kind of taking all of that information and data there for you.
Sounds great Maritza. As we move along here, I think we can get some really easy to see examples and we can work through that problem and see how would we end up and hopefully that'll be helpful to doctors and staff who may be involved in coding.
