Vijay, Send them an email like I did, because like you, I was on hold two different times for long periods of time with no answer. Liberty will state this apology to you; that they are very sorry because they did not expect the volume of Medicare orders for the Dexcom G5 from all over the country that they are trying to process.
They answered my email last night, and a Liberty Medical rep also called my wife today. Dexcom may have pushed them along as I also called Dexcom and complained to them about no replies for three weeks after the Dexcom sales rep submitted my wife's paperwork.
Although, there's still a lot more to be done, after my wife's phone call with the Liberty Rep today, they are requiring some more paperwork from her doctor, and Liberty will be doing the contacting of her doctor to obtain it. OBTW: At the end of her phone call, the rep asked her if she would like to purchase some supplies now? She politely said No, not until she receives the G5. These supply outfits are always trying to make a $.
Also, If you are a NEW Dexcom patient, Medicare/Liberty still wants the 60 day log of BG's. My wife is going to use her OmniPod PDM to try and extract at least 30 days worth of data.
