i work for a breast surgeon who was called to the ER to consult on breast abscess. she performed and I&D of the abscess in the ER and proceeded to take the same pt to the OR that afternoon for a surgical debridement of the wound. so it would be the consult to the ER with a modifier 25, then the procedure in the ER, then the procedure in the OR later that day. the question that I have is which modifier do I use for the trip to the OR for the debridement,? I am thinking wither 59 or 58? I am rather new to the surgical coding and this is the first time that I have had an encounter such as this one to code. the pt was then admitted to the hospital for 2 days. thanks in advance for any and all advice....it is greatly appreciated!
