What is the appropriate code for reporting CORNERSTONE, TANGENT, PRECISION-GRAFT and other tricortical allografts?
Per the February 2005 edition of CPT Assistant, all structural allograft bone used for spine surgery should be coded as 20931. The only exception is for threaded allograft bone dowels as they should be coded 22851. In addition, code 22851 is also appropriate for intervertebral devices made of PEEK or metal.
