I have been struggling with this one lately myself. Recently had both an injection and a destruction by injuction and was not sure what to use. After reading the responses posted here, I still am not 100% sure what codes were the right ones. I believe the 64640 woud be correct for destruction, but is it the 64450 or the 11900 for the injection? If the 11900 code is correct that would indicate a lesion being injected which then makes me wonder if I should use 17000 and +17003 for the destruction? Very confusing
I code surgical procedures for anesthesia and our pain clinic has just started doing these injections in peds in the OR, so I'm stumped. Thanks for any input that anyone has.
