I am a biller in a family practice clinic and recently we are getting denials for G0444 with modifier 59 and diagnosis code Z71.89. It seems that the diagnosis code is "invalid per NCCI edits". We do many Medicare Annual Wellness Visits and have always used this diagnosis for G0444 and 99497. Does anyone have any insight on why this is now being denied and the proper diagnosis code to use for this? Any help would be appreciated.
