Debridement done in different are of shoulder?

For Medicare, is appropriate to add mod XS to 29822 if debridement is done in glenohumeral area with a rotator cuff repair (29827), or should we never use modifier 59/XS ever on shoulder procedures that are bundled for same shoulder since CMS considers the shoulder one anatomic site.

Any thoughts are comments are greatly appreciated!


  • Please look at the NCCI Chapter IV Policy Manual page IV-7#7  the guidelines for limited debridement 29822 in the shoulder are defined.
