Debridement Coding: Selective Versus Surgical And What Payers Require

Debridement is billed at almost every wound care visit, and it is denied or downcoded more often than almost any other wound care service. The code depends on the method, the depth of tissue removed and the surface area treated, and each of those must be in the note.

Selective Debridement

Selective debridement (CPT 97597 for the first 20 square centimeters and 97598 for each additional 20) covers removal of devitalized tissue without removing viable tissue, using instruments such as scissors, scalpel, forceps or high-pressure waterjet. It is reported by the total surface area debrided, not by the number of wounds.

Surgical Debridement

Surgical (excisional) debridement codes 11042 through 11047 are selected by the deepest level of tissue removed: subcutaneous tissue, muscle or fascia, or bone. Each depth has a base code for the first 20 square centimeters and an add-on for each additional 20. The depth reported must be the depth of tissue actually removed, not the depth of the wound.

What The Note Has To Say

Payers and auditors read the procedure note for specific elements. When any of them is missing, the claim is denied or paid at the lower selective rate.

  • Method: selective or surgical, and the instrument used
  • Type and depth of tissue removed
  • Wound measurements before and after, and the surface area debrided
  • Anesthesia or hemostasis if used, and the patient's tolerance
  • Medical necessity: why debridement was needed at this visit

Common Denial Reasons

  • Surgical debridement billed with documentation that only supports selective
  • Surface area not stated, so the add-on units cannot be supported
  • Debridement billed on the same day as a skin substitute application without the required documentation
  • Frequency beyond what the MAC considers reasonable without documented progress

Frequently Asked Questions

Can selective and surgical debridement be billed on the same wound at the same visit?
No. Report the code that describes the deepest level of tissue removed on that wound. Different wounds debrided to different depths can be reported separately with the documentation to support each.
Is debridement payable with a skin substitute application?
Payer rules vary. Many consider site preparation part of the application. When debridement is separately reportable, the note must show it was a distinct, medically necessary procedure.
