My doctor is doing an in office procedure where she is doing a bone marrow aspiration from the hip and re-injecting that into a tear of an Achilles tendon. The notes do not say anything at all about spinning the aspiration in a machine. Just describe getting the bone marrow aspiration and basically using that same syringe and putting it back in where the tear is. She says this is definitely not a PRP-0232T and that this is an injection of stem cells and tells me there are no platelets at all in bone marrow aspiration so the 0232T code is wrong. Should this be coded as 20999? Any help would be appreciated and any articles you can link would be awesome!
