First, a Medicare Appeal Process is a challenge. Do NOT give up. My suggestions for a starting point is: https://www.cms.gov/Outreach-and-Education/Medicare-Learning-Network-MLN/MLNProducts/Downloads/MedicareAppealsProcess.pdf. This is the current directions as of November 25, 2016.
Consider this a game and our goal is to play to win. I understand that for some of you your feelings are important. But, by the time to hit the third level with an Administrative Law Judge it becomes a question of fact.
what do we need, why do we need the CGM? Can you prove it works?
Can you document your success? Having an Endo on your team helps. It is my understanding that some 30 individuals have received ALJ approvals. How, here is where the current fight exists. Should the fourth level, see the above referenced guide, is forwarded up to the Medicare Advisory Council, an approval at this level would by default define a positive answer - meaning a method for CGM approval. Cases forwarded up to the MAC are being forwarded back to the ALJ. The ALJ do not want to re-open closed cases. So, give your appeal the best fight possible. Reach out to individuals for help. You can do this and succeed!.
As always have a great day and blessings for the Holiday Season.
