Answer: The answer depends on your date of service. In the past, CMS did not subject G0289 (Arthroscopy, knee, surgical, for removal of loose body, foreign body, debridement/shaving of articular cartilage [chondroplasty] at the time of other surgical knee arthroscopy in a different compartment of the same knee) to the multiple-procedure rule.
Most orthopedic coders took this to mean that the code's value was already low because CMS knew that surgical practices would report G0289 only with a meniscectomy code (such as 29881, Arthroscopy, knee, surgical; with meniscectomy [medial OR lateral, including any meniscal shaving]).
Therefore, coders and payers treated G0289 like an add-on code, which meant that no multiple-procedure reduction applied.
However, CMS recently released Change Request 4031 with an implementation date of Oct. 3, 2005, which changes G0289's multiple-procedure indicator from -0- (which meant that Medicare payers did not subject the code to the multiple-procedure rule) to -2.-
This means that the multiple-procedure discount of 50 percent applies to the code. Therefore, you can now expect half of the reimbursement than before for the G0289 claims that you submit to Medicare carriers.
