Does the compression garment require a full-thickness debridement (11042) in order for the dressing to be covered by Medicare?

CPT 97597 is fine for EXTREMIT-EASE and 11042 is not necessary. In the surgical dressing LCD and LCA, a thickness requirement for compression garments is not noted. So all you need is:

1. Medical necessity (edema/stasis)
2. An ulcer that was debrided or caused by a surgical procedure
3. Drainage documented
