What did ya'll use for the second stage? Because it feels like we are doing part of the 29888 the first time.We had a similar case. Our patient had a previous ACL reconstruction with quadriceps autograft. Then experienced a re-tear of the ACL and medial meniscus tear. The repair was performed in 2 stages. For Stage 1, since there is no code for a REVISION arthroscopic ACL reconstruction or for the tunneling bone graft, we reported unlisted code 29999 with comp code 11044-22 for debridement of the graft plus placement of a new allograft. He removed other hardware, so we coded 20680.
The provider wanted to use a bone harvesting code (20900, 20902). However, these codes are only to be reported when the graft is harvested from a “separate” site through a separate skin or separate fascial incision, and “when the graft is not already listed as part of the basic procedure,” according to notes at the beginning of the Musculoskeletal System Section of the CPT Manual. Since an allograft is being used in this case, neither of these codes would be appropriate.
