Wiki Modifer 59,79, or none?

[coders_rock!]

If a patient received a surgery with a 90 day global, goes onto the recovery floor, then later on comes back to the operating room for a different procedure, should I use modifier 59 or 79? Should I bill the two different CPT codes on separate or different invoices?

Thank you for your help!

78 modifer for unplanned return to the OR

 

[mitchellde]

if the second procedure is related to the first then it is a 78 if the second procedure is unrelated then it is a 79.

Thanks to both of you, the appropriate modifier is 78.

Do you suggest using a separate invoice?

Have a great weekend!
