Thread: Dermatolgy modifier

    Default Dermatolgy modifier

    AAPC: Back to School
    I just started at a Dermatology office which I have never coded before. I found the previous office manager was billing pathology code 88305 with a modifier 79 than billing another 88305 for the second site with a modifier 79 and adding 1 unit for each. The first one is getting paid and the second is getting denied.
    Wouldn't the second 88305 get a different modifier to say this is a second site.
    Thanks for the help.

    Default dermatology modifier

    I think the modifier you are looking for is 59. WPS Medicare has a page on using modifier 59 with cytopathology codes - when specimens are taken from different lesions/areas.

    Our payers in Washington state recommend billing the 88305 in units.
