I have seen a lot of discussion about this on another forum, and the last thing I heard was that Medicare will simply not pay for this when done on both ears at the same time. They even put it in the Federal Register. Their stance is that the chances of it being done on both ears is 10% of the time, and they have factored enough RVU's into just billing it once to pay for both ears.
If they have since changed their stance, I have not heard they did. Some other payers have the same stance, I think UHC is one of them.
