How to bill 12032 and 13121 codes

I though 13121 is to remove debridement and 12032 is to repai the wound. So can bill both together. I got rejected.

How to bill 12032 and 13121

CPT says 12032 is an intermediate repair, and 13121 is a complex repair. Complex repair should include debridement as well. I would only bill for 13121, unless you are using 13121 for different site, in which case I would append mod 51. If you've done all this, definitely appeal!
