    Default 58 Modifiers- Can they be placed on add-on codes?
    Clearnace Sale
    I have a question in regards to the -58 modifier:

    Can they be placed on add-on codes?

    For example, say I have billed:
    22214; 22610; 63047; 22843; 22848; 22216; 22614; 63048 (with a -59 on the 63047 for a valid separate site).

    Would I place the 58 modifier on all codes billed or just the primary ones?

    I cannot seem to find any solid documentation on this (if you know where to locate it, I would be most grateful) and am currently going back and forth with an insurance company in the matter and I am stuck.

    Please help! I appreciate your time and help in the matter.

    I do not believe they would be needed on add-on codes. Each add-on code relates back to the primary code, so if the primary code has -58, then they add-on codes don't need it. Having said that, I don't think you would hurt anything by putting them in.

    That's what I thought as well, but i had always coded a bit "safer" placing that modifier on all codes. When you place a -58 on any of the add-on codes (22848; 22216; 22614; 63048), these will completely close out the claim and not even be reviewed by a large insurance company. We have not had a problem with this in the past, only until November 2009 did they start "closing." When this happened, I wanted to make sure I was on the rigth track with this modifier, but could not find documentation that talked about the modifiers with add-on codes.

    I appreciate the advice, greatly. I think I will refile these claims without the -58 on the add-on codes.

    We don't normally place modifier 58 on the "add on" codes; however, some carriers are more difficult than others. We'll add modifier 58 to the "add on" codes on carrier by carrier basis...
