I currently work for a facility that bills out IOP with 90853 with a 22 modifier, and REV code 906. When I look this up in CPT book . I do not see supporting documentation that 90853-22 is IOP it is group therapy. H0015 is specifically for IOP. Management indicates that the modifier 22 is what they use to indicate it is different from group. I do not agree with this at all. Would you be able to give me supporting documentation
Thank you,
