Coding for non-open procedures involving arthrodesis of the SI joint has continued to evolve since 2014, when the AMA CPT Editorial Panel issued a permanent Category I CPT code to report minimally invasive or percutaneous SI joint fusion procedures: CPT 27279, Arthrodesis, sacroiliac joint, percutaneous or minimally invasive (indirect visualization), with image guidance, includes obtaining bone graft when performed, and placement of transfixing device. This code became effective in January 2015.

In May 2022, a new Category III CPT code (0775T) was introduced to describe percutaneous placement of an intra-articular stabilization device or implant into the sacroiliac joint using a minimally invasive technique that did not transfix the SI joint. It remained as a Category III code until January 2024, when code 0775T was deleted and replaced with a new Category I code, 27278. This was previously covered in a SpineLine article from March-April 2024.
