Working in pain management. We bill the following combination often with no issue. However, an Arizona Medicaid plan is denying the 64483 and 64484 with "Procedure code inconsistent with modifier or required modifier is misssing". Upon query at the payer, they verified the modifiers submitted were valid for the code, but provided no further explanation. I have been searching policies, LCDs, NCDs, etc with no luck. Does anyone have an idea what the issue might be?
