Wiki Modifier need on a 93010 when billed with 99281-5

[Treavis]

I am being told in order for a claim to go thru and get paid that 59 modifier has to be amended to the interpretation 93010 when also billing the ED EM code group 99281-99285. I just can' t see why a 59 modifier has any bearing in this scenario. If any one can help with clarification on this is would be greatly appreciated
