hmm...so either CCI Edits is incorrect or payers are paying incorrectly? I don't know, I tend to follow CCI Edits, they haven't lead me wrong yet
I disagree with Donna as the AMA has documentation that supports the use of the -59 modifier.
If your documentation clearly supports that you are in a different compartment (either medial or patellofemoral), it is codeable with a 59 modifier. If the chondroplasty was performed in the lateral compartment you will not be able to code it.
I DO have documentation to support the above statement as well and will be happy to repost it or you may find it in other threads under the orthopedic section.
Hope this helps
Can you share that documentation? I have a BCBS patient that had lateral release and chondroplasty of the inferior pole of the patella. I would like to be able to bill for both 29877 and 29873 because of being in two different compartments.
