Tricare & pumps?

Cadence goes to Vanderbilt on Monday the 2nd for her pump class where she will try them out & order one if we decide to go that route. My husband, Cadence & I have talked it over & we do want to go the pump route. I have called Tricare to check on pumps & coverage & they have given me 2 answers: since the pump is considered DME it is covered 100% & another rep. told me she was not able to tell me anything with out an insurance code. So I was wondering if anyone HAS gotten a pump with Tricare Prime? We are debating between the Ping & Paradigm. Any info would be great!
