yes, be sure to check with AT&T to see what type of plan they will provide.
medicare A has no premium, B does. I processed claims for 20 yrs and retirees who did not have B. we extimated medicare would have paid 80% and we just considered the 20% balance that would have been left after the medicare payment, then paid that per their plan language. BECAREFUL!
also, check on rx coverage. do is not good but better than nothing, i guess.
if you are a vet, apply for VA benefits, if only for the rx benefits. The Va have relaxed the requirements.
Good Luck!
