The process was super easy. I filled out the form and uploaded my prescription that was provided by doctor. You can pick from a list of different pumps approved by Tricare - it will tell you if there is an extra charge. While filling out the form - you also can receive your breast pump bags (provided by insurance). I received an email shortly letting me know the extra charge amount - I had a few options - pay over the phone, on a website or I could change my mind to a different pump. I decided to change the pump to one that is fully covered. The process was just as easy - just emailed them back letting them know which one and it was shipped to me a few days later.
