My daughter's first set of tubes lasted about 12 months. after the second set was placed, she had some sort of reaction to the tube in one ear that the ent had only seen once before. it needed to be replaced but the ent did not charge anything for the replacement. We did have to pay our coinsurance for the anesthesiologist and part of the surgery center (i believe the ent called them and got us a discount- at least on our coinsurance). the replacement tube has made it 11 months so far. good luck.
