We perform several debridements on patients in the office for venous stasis ulcers. Some are very large in nature. For example the one that I am having trouble with has One on the right leg measuring 12cm x 18cm., left leg 13cm x 20cm. They both include sub q. So the debridement code would be 11042. However the new code now reads for the first 20sq cm. then use 11045 for each additional 20sq cm. In my calculations that is at least 476sq cm. That would be using the add on code several times. My question is "IS THAT THE CORRECT WAY TO CODE THIS?" It does not seem correct to me but I am at a lose if it is not. Would someone please help me.
Thank you
