My physician placed segmental instrumentation in November from T3-T11 with Crosslinks placed at T6 and T8. In March the Crosslinks started to come through the skin so my provider decided to remove the Crosslinks only. No other surgery or instrumentation was replaced or inserted. I coded this as 22899 but the coding educator from our group disagreed and states this should be coded as 22852. Can someone please provide some additional information for removal of Crosslinks? If this is considered segmental 22852 should I also add modifier-52 since the entire instrumentation was not removed?
