What 11047 covers
11047 represents additional wound area debrided at bone level after the initial area has been captured. The clinician removes devitalized bone as part of wound-bed preparation or treatment of a deep ulcer or complex wound; overlying skin, subcutaneous tissue, and muscle or fascia may also be removed. Surgeons, podiatrists, and other clinicians performing wound debridement may report it in office, outpatient, or hospital settings. Bone that is simply visible in a wound, without debridement at that depth, does not establish this service.
Report 11047 only with 11044: 11044 accounts for the first 20 sq cm or less, and 11047 is used for each additional 20 sq cm or part thereof debrided through bone. Choose the depth from the deepest tissue actually removed, and calculate area from the wound surface debrided at that depth. Documentation should identify the wound site, deepest tissue removed, area debrided, and bone work performed. CMS classifies 11047 as an add-on, so it is not billed alone; payment falls within the primary procedure's global period.

11047 billing questions
Can 11047 be billed by itself?
No. Report it with 11044, which represents the initial 20 sq cm or less of bone-level debridement.
How many units of 11047 should be reported?
Report a unit for each additional 20 sq cm or part thereof debrided through bone after the initial area represented by 11044.
Does exposed bone qualify for 11047?
No. The documentation must support debridement through bone; bone merely visible in the wound is not enough.
When is 11047 appropriate instead of 11046?
Use 11047 when bone is the deepest tissue actually debrided. Use 11046 when the deepest tissue removed is muscle or fascia.
What documentation supports this add-on?
Record the wound site, the deepest tissue removed, the surface area debrided at bone depth, and the bone debridement performed.
