Not from the perspective for obtaining insurance coverage for the implant, for several reasons:
1) Several insurers (United Healthcare being the largest) have overall corporate policies specifically excluding CIs for pre-lingually deafened adults. Once the child turns 18 and can legally make the decision on their own, if they are insured by one of these plans, they couldn't get the insurer to pay for an implant.
2) The federal government in the US mandates coverage for cochlear implants through Medicaid for children, but does not mandate the same coverage for CIs for adults. Many states specifically exclude CIs for adults on Medicaid, and I personally know of at least one family that packed up and moved to another state so the adult on Medicaid could get coverage for the CI she decided she wanted after she turned 18 when she had declined to get one that was offered to her when she was younger.
3) Once children become adults, they frequently are forced to drop off their parents health plans. If they are students and pick up their university's health plan, there is likely no coverage for CIs -- I have yet to see a University insurance plan include coverage for CIs, and I've looked at dozens of them. If they buy an individual plan, the insurer is allowed to discriminate against them -- so the insurer can say "we don't want to insure you at all, you're deaf" or "we'll insure you for everything but hearing impairment related illnesses" Once again, no coverage for CIs. If they get a group plan through a job, there is an 88 % chance that coverage for a CI is included, but if there was more than a 63 day gap between when their previous policy ended and when the group plan begins, once again, a pre-existing condition exclusion can kick in -- the exclusion is temporary, but it can cause an up to 18 month delay in getting coverage for the CI.
I'm not saying that coverage should be the only concern, but it is very frequently a factor given that most people can't just whip out their checkbook and write a $60,000 check for the surgery if they can't get insurance to cover it. Bottom line is if insurers can legally avoid writing a large check (for anything, and CIs really aren't an exception in this matter) they will.
