Wiki IV Hydration and Infusion Codes with Modifier 59

[myndi13]

Hello,
I need to know the correct way to bill those very confusing IV hydration and IV therapeutic, prophylactic and diagnostic injection and infusion codes with the modifier 59.
Should the 59 be appended to the base code such as 96360 or 96365?
I keep getting denials from AHCCCS stating that the codes are unbundled

I may be wrong but I don't think you can bill 96365 with 96360. I believe it should be 96365 then 96361 as your secondary.
