Lloyd,
Melissa's and
notme's advice are right on. It depends on your insurance company, and they don't look just at your A1c level. With Type 2 diabetes, you've got to meet a different set of guidelines than from Type 1, which will likely include the C-peptide blood results.
It completely depends on your insurance company. Some companies, such as Cigna, actually post their policies for the world to see.
You can, of course, get on a pump with no problem if your doctor prescribes it and you pay for it all out of pocket.
Most insurance companies consider several factors, including (but not limited to) glycemic excursions (have you had dangerous lows or highs that resulted in hospital ER visits or admissions?), A1c, frequency of injections (with 70/30 insulin, you're pretty much stuck to 2 injections per day (insignificant compared to the MDI that most pump users have escaped), and current complications (if your kidneys are failing, you have a better chance).
Since you're on 70/30, and the common prescription is for two injections of it a day (for the NPH insulin protamine to cover 24 hours), a pump is unlikely to be covered at all.
FYI, Funnygrl is right -- you'd best get practice with the basal/bolus way of a pump by switching to a different insulin regime if you want to consider a pump in the upcoming years!
Good luck!
