Wiki Coding for Abscess

[hgarrett113]

I have a patient that has been seen in my office several times in one month due to an abscess. She has also been admitted to a hospital (where my providers saw her) and now has followed up back in the office. The insurance company is denying for global package. I need help on how I should code these visits. What modifiers should I use so all visits will get paid?

You didn't say specifically what's been done for this abscess. The usual I&D codes have a 10 day global period. Any routine f/up visits for this abscess within this 10 day period should be coded 99024. Same applies if a major surgery was done that has a 90 day global.

If the f/up office visits are unrelated to the abscess or fall outside the surgery global rules then you will want to add mod -24 to your E&M
