One session One CPT
For an accurate response to surgical coding questions, please post the scrubbed operative / procedure note. That being said ...
This comes from Encoder Pro
When 20680 is performed with another separately identifiable procedure, the highest dollar value code is listed as the primary procedure and subsequent procedures are appended with modifier 51. If two separate, unrelated incisions are performed to remove different implants, report 20680 twice and append modifier 59 to the second procedure. (Emphasis added by FTB)
ALL ONE OPERATIVE SESSION
If you are removing multiple pins through ONE incisions, you report 20680 only once.
If you are removing hardware from multiple sites, through different incisions you report 20680 once per incision and use -59 modifier on second (or third) case.
DIFFERENT OPERATIVE SESSIONS
If you remove hardware from one site on one day, and later return to remove additional hardware from the same site or a different site you will use a -58 modifier for a staged/related procedure if the second operation is in the global period of the first.
Hope that helps.
