Using Tricare For Life (Military Retiree) in DR?

Any retired military out there that use Tricare for Life (TFL) within the DR?   

How is it working out for you?   

Can the local places bill TFL direct, or do you have to shell OOP and then seek reimbursement? 

Any problems finding providers that will TFL? 

And anything else you feel would be useful to know.

Many thanks,

Jim

I will be following this with interest. My understanding is that it does not work here.
