I recently had an encounter with United Healthcare that initially resulted in a denial of a request to treat one of their patients with UPJ stenosis (partial obstruction of the drainage leading from the kidney to the bladder) with a robotic repair of the condition. The denial was initially based on the perception that such surgery was “experimental” and not a generally accepted form of treatment. After nearly two months of back and forth, I have approval to do the procedure and I believe I have convinced United Health to accept the procedure generally for all its subscribers. I have posted below several references to articles that I forwarded to the medical director in the course of our discussions. Most pyeloplasties are done in children and you can see that the articles reflect that, although my patient was an adult. Perhaps they will be of help to someone else in a similar situation.
