Keeping adult child on parent's health insurance

We absolutely kept our kids on our insurance until they were 26, despite their being offered plans through their employers (and S was/is a federal employee). They declined the coverage from their employer. No issues at all. The only hiccup was nagging them to make sure they kept up with the preventative care visits required by our plan - failure to comply would result in a premium increase for us.

Another consequence of keeping your kids on your plan is that you have access to their healthcare details within the account, which one or both parties might not ideally want.

We also have a wraparound policy thru DH’s work that covers all out-of-pocket expenses from the primary insurance, so I have to remind the kids to send me receipts for co-pays and other out-of-pocket expenses because submitting that info is not straightforward, and even if I taught them they wouldn’t do it (plus then they would have access to parent healthcare details.) So, in an even more immediate way I know if they went to the ER/urgent care, visited X specialist, was treated for X, saw a therapist who doesn’t take insurance, etc.

For us, it’s only about $10 more/month to have “family plan” than just H and W plan. It’s well worth the peace of mind for us because we know H has excellent plan that allows us to see anyone anywhere. D is a medically disabled dependent and allowed to be covered under H’s plan. She has been able to get great care in CA at nearly every MD she wished, nearly all are participating & preferred with BCBS, including Stanford, USC & UCLA.

Do the math on vision and dental.

These are profitable plans for insurers for a reason, folks! IF it works for you and your kids-- after pricing out what’s covered, what your predictable needs are likely to be- FANTASTIC. But many employees just check the box (who doesn’t love a pair of free glasses?) without running the numbers and realizing that you may have one year where it makes sense- so you stay on the plan-- and then have five years where you’re paying more in premiums than you are getting back in coverage so are in a net loss position- and inertia means you stay on the plan, and on and on and on


Happy they’ve worked for many of you. Win-win!

Probably different for different carriers, but we do not have the ability to see details of services provided for others in the plan (18+). I can’t see H’s and he can’t see mine. And when the kids were in the policy as adults, I couldn’t see theirs.

For the required preventative care, we each get letters with details of what’s outstanding, and H (the plan owner) gets a separate letter saying that someone is out of compliance with something.

At the time, I insisted on knowing the kids’ login to the compliance site (different from their healthcare portal login) to be able to see who needed to be nagged, and for what. :roll_eyes:

My husband currently has 3 medical insurance plans. Medicare is primary, Medicare supplement is secondary, and then he is part of a special insurance plan that will cover everything the others don’t for specific conditions only.

Providers never get it right and when they don’t submit in the right order with the right codes things don’t get paid.

From my personal experience, having multiple insurances (primary and secondary) can mean having to spend time getting the billing done correctly by your health care providers. YMMV

But isn’t that better than having to pay the bill yourself? You, and your husband, must feel it is worth it to have 3 policies

I only have one insurer and I still have issues with mis-coded things, things not submitted to insurance, submitted late. Right now I’m dealing with a mammogram from Nov that hasn’t been paid. The insurer seems to be right on this one as my EOB denied the claim but said I don’t have to pay because it is a mammogram that is to be paid without co-pay. I think the provider is coding it wrong. Provider won’t clear the account. I don’t have that insurer anymore and can’t use that provider anymore. I just want it gone.

The third insurer is free to us (9/11 insurance from the federal government). Yes, in general there are always problems with health insurance payments (as you state), but having the provider bill in the right order adds a level of complexity to the process.

I am pretty good about persisting and being sure that bills get paid. For 5 years, bcbs kept sending bills to Medicare B for primary tho he didn’t have it since he was still working. I would get bcbs to pay as primary and we would pay out tiny copay. It worked.

My immediate thought was loss of HSA access, as others above have suggested.

Assuming a HDHP is what he’d select, if he has that plan on the last month of the year then he’s eligible for a max HSA contribution for the full year as long as he continues to be eligible for all of next year. Look up last month rule for details.

Of course, the value of the HSA contribution to him depends on the salary and marginal tax rate as well as whether he’ll be maxing out the 401k. Those who see the HSA as very valuable are usually maxing out 401k contributions and for the most part aren’t planning to use HSA funds in the short term (they can be used tax free decades later for eligible expenses, including Medicare premiums).

Employer contributions are worth capturing if the math works.

Ultimately it’s probably not a big deal for only a few years, and if there’s a major medical expense he will pay more with the HDHP.

If you think the provider is wrong and they persist call the billing department and tell them you will be calling your insurance company and referring it to the “insurance fraud/balance billing division for investigation”
Then call your insurance company and do it!
It’s amazing how quickly that can get results. I had to do that with an issue I fought for 9-12 months. After I did that the provider called that afternoon and said my account was zeroed out.

I already told them I’m not paying. I was setting up a payment plan for LAST year’s copays that they were slow in billing so carried over to 2025, and I’m just paying slowly since they billed slowly. When setting it up, IN JANUARY, the guy said “Just so you know, they haven’t cleared the mammo bill.” I told him “Just so you know, I’m not paying.” That was Jan, now it is May. They haven’t paid yet.

It’s just that they have the account still open and I can’t go there anymore because of the change in insurance. They didn’t actually bill me for it, and the EOB says they can’t.
