    This came up at work and I was just wondering what everyone else was doing.......How do you use Modifier 99? Is it payor specific in your coding? Under what types of scenarios?

    Any feedback is greatly appreciated.

    I found this website that shows an example of how to do it. I really don't see the use for it because you can have multipule modifiers on a code. I guess if you have more than 4 modifiers you have to use on one code than it would be helpful.

    I have used modifier 99 soley for california medi-cal. They require you to append the 99 modifier if you need to use more than 1 modifier to describe the service. You then itemize the modifiers in Box 19 of the HCFA 1500
