I believe that the FDA has only approved them for
shingles neuralgia. The company has to do studies for other
conditions etc.

Insurance companies use this tactic to get out of paying for things.
The Lidoderms have generalized to many other pain conditions.

I get mine easily since I had shingles, testing for it and diagnosis sent at the time. Lidoderms were not out yet. But when they did come out, I already had that diagnosis logged.

Here is the policy of use and coverage for Express Scripts:

TriCare has always been odd and limiting.

This is the new TriCare document --

It suggests, that neuropathic pain is covered. Getting a prior auth. is just your doctor faxing them a document with your diagnosis on it. You will probably be approved.

My husband had to get Prior Auth for his Dovenox cream for his psoriasis. The doctor's office did that for us over the phone.
It was not TriCare however. It took one day. They all differ.
