I received a denial for 29819 coded with 29823. First is removal of loose body, it was 2cm, shaved first and removed when small enough through a portal, no extra incision. 29823 was extensive debridement of humeral head, labral tear and ticking chondral defect. Margie Vaught claims AAOS says it is ok for LB removal over 5mm [2cm is a little over that]. Insurance co claims that AAOS requires separate incision. If you read 29823 it says that w/o size moniker. Anyone have AAOS citation as per Margie? Thank you, Michael Loss.
