Debridement of ulcers (any open wound) is coded in the 110XX. The physician needs to document the size of the ulceration and the tissue depth of the debridement (skin/subq, muscle/fascia or bone). It's been my experience that physician just love to document that the "wound was debrided". That's meaningless. In podiatry it's common for a patient to have multiple open wounds. Each one that is debrided must be documented separately according to size and tissue depth. It's also been my experience, especially those who treat the feet, the physicians incorrectly label procedures that are performed. They love documenting an "I&D" even though that's not what they did. So you have to read very carefully. Most of the time they want you to bill an "I&D" code when debridement codes are what is documented. I have a powerpoint that goes over trimming of nails and things like that. I can email it to you if you would like.
