I have been fighting with UHC Medicare complete regarding them not paying my debridement codes. I billed 11042, and 11045 x 4, wound is 89.10sq cm, dx codes L97.519, l97.919 - Rt leg and foot. I also billed 11043 and 11046 x 5, wound is 109.8sq cm, dx code L97.529, left foot. The debridements were different depths, and obviously in different locations. I have already gone through the appeals process, which means I have sent notes highlighting the types of debridements and location. The claims are still being denied. Is there something else that I am missing or where do I need to go from here?
