I have received billing from an osteopath who is doing manipulation under anesthesia of all body joints. ie(shoulder, elbow, wrist, hip, knee ankle) Although I have found information for the code 22505 for spinal manipulation under anesthesia used by chiropractors and osteopaths, I can find nothing on the other joints. He is using surgical codes 23700, 24300 etc. which I would expect to see on surgical codes for orthopedic injuries not for manipulation. Does any one have experience with this type of billing?
