debridement of skin flap

Hello, I am a coder at a doctor's office in Arizona and would like some guidance on what to do from my fellow coders. Patient came in with a skin flap (debridement) the patient had a superficial laceration of the toe, but the doctor only debrided the skin flap from this superficial laceration. I don't know how to code this. Any and all responses are appreciated. Thank you,

Stephanie G.
