Dr performed an irrigation and debridement on a patient, down to bone, on his right shoulder and back area. A few days later Dr took him back to the OR for an irrigation of the same area. I am not able to find a CPT for just an irrigation. I'm thinking it's included in the primary procedure, but I hate to that to my Dr. Am I right with thinking there is not a code for just an irrigation of a post op wound or am I just not seeing it. Please help!
