93922
Thanks for the reply. That was my thought. My concern is that this provider is billing both LT and RT and attaching the 59 modifier on the LT- in some cases she is getting paid. I think that the 59 modifier is overriding the claims adjudication system and while she is receiving payment, my concern is that this provider will come under audit for abuse of the 59 modifier.
93922 - states one level, for the ABI procedure measurements are taken at both the brachial and the ankle level on both sides. I think the provider thinks since two levels she can justify the use of 59. However, I think since the procedure inherently includes bilateral, both ankle and brachial it should be just the one code.
