I am trying to make sure that I code this correctly. My doctor treated a patient that had a previous hemi several years ago by doing a total knee. He removed the hemi components and replaced with total knee components. He turned in 27447 for the total knee but I am thinking that I need to code this with the 27487: revision of total knee with a 52 modifier for the reduced services since the patient had the hemi in the past and not a total knee. Any thoughts?
 
You are absolutely correct. This will give the surgeon credit for removing the old components where as 27447 does not. The 52 is applied because the patient is going from a hemi to a total. Nice work!!
