I'm needing help, if anyone has experience or knowledge in anterior surgery of the thoracic spine. The procedure is for vertebral body stapling from T6 to T12 with Medtronic staples.

So far all I have is what the physician coded 22810 (which may not be correct because there was no fusion done) with add-on code 22846. We are ok with the add on code. We have searched all of the possible codes under 22846 that may be associated with the procedure. None are correct to what was done. Also doing my research I notice that many carrier policies consider this investigational/not medically necessary. Patients (there were two separate patients, same procedure) insurance is Blue Cross Blue Shield of Kansas and the other was United Health Care....any guidance would be so appreciated. Thanks in advanced!
