I think most of problem is Edge Park. I’ve had quite a few problems with them understanding what I need. That said, the nurse should be calling in the order and work out the code. I’ve given up on getting more than one lube tube per month because Medicare won’t cover, even if the nurse or doctor says it is necessary. in fact I don’t get any lube from them because i was bothered as to how much they charge the government. I simply couldn’t be a part of that scheme or whatever it is —My small contribution for keeping down medical costs. Ha. I can get a 4 ounce tube for 2$ including ship, so long as I order 20 or so.Each time I order I really Google for the best price.
