I work with a Pain Management Specialists & we several patients with pain pumps. We provide several patients with Clonodine J0735 in their pain pumps. We have billed up to 60 units and never got denied with Medicare. Now they are denying this with CO-151 for frequency of testing/units. I have researched this for weeks now & I cant find the answer to the limit that Medicare will pay for. If there is someone else out there having this problem. I would really appreciate your advice.
