I use code L093590 which provides CDW, but I also buy premium insurance for $19.95 per rental from AMEX. In my case the rentals are generally for several days or more, so the backup insurance is only a few dollars a day. I have had several small accidents over the years using the same code, and I have never heard a word from Avis.
