It seems that medical providers can charge cortisone injections as outpatient surgery, at least mine does. My insurance covers injections, but because the cortisone shot is billed as a surgical procedure, I'm stuck with my outpatient surgery co-pay. I appealed to my insurance, but they told me the AMA considers cortisone injections as surgery. So I tried to contact the AMA to verify, but can't find a phone number for info. The phone numbers on the website are all automated, with no chance of talking to a real person. If anyone else has any info, please let me know. I ended up e-mailing the billing director at my provider, and they ate the co-pay. This happened 3x already, and now I think another finger is starting to lock up. I think this is discrimination, because older people tend to need these injections. To make it sound like surgery, and get billed for operating room services, is outrageous. But good luck trying to get to the bottom of this. I had cortison shots 5 yrs. ago, got copies of the older bills, and they were NOT charged as outpatient surgery. Something is terribly wrong here.
