I cannot find which modifier to use when billing an 99213 during the post operative period. The office visit was totally unrelated to the surgery. I have tried 24 and 79 both being denied. Please help!!
I would appeal the denial as -24 is correct for an E/M during the post op period. Doublecheck that you are not billing with a diagnosis related to the surgery. Can you send chart notes with your appeal to prove its unrelated treatment?

79 would not be used with E/M but 24 is the correct modifier, that is what I use all the time. As previouse person stated, make sure Dx is for new problem only.
