Does anyone who is billing for wound care, know if there is a limit to the number of units you can bill to Medicare for the 97598 debridement code? There is a patient that has an area over 900 cm's which is well over 40 units, but I don't want to bill the units if they are just going to get denied. I've researched and can't find any limit. Anyone with thoughts, past experience or help is greatly appreciated.
