Help! I have a surgeon who insists on coding a 20936 (autograft) when he mixes together beta tricalcium phosphate (allograft), with bone marrow aspirated from the patient. Has anybody else ever heard of this? I believe this should be coded as a straight allograft 20930 and bone marrow aspirate 38220. Any opinions? This is for a revision lumbar laminectomy.
