I apologize if this isn't the best sub for this question, but searching Reddit for HDHPs led to an older post here.
Here's the situation: my husband has been covered under my employer's insurance program for many years on my family policy. Within the past few years, he has enrolled in a HDHP through his employer so that he can have the HSA. He does not use that insurance, and instead uses my (employer provided) health insurance. I am getting ready to retire and am enrolling in insurance through my pension provider. I feel that I have to list his insurance through his employer under the Coordination of Benefits section on my application.
How *should* insurance work for him given that he has his HDHP and coverage through me? My thought is that everything should run through his insurance first and then through mine. Is that correct? If so, how would that impact things like copays and deductibles?
If he does not utilize his HDHP and only uses my insurance, what are the possible consequences of that, if any?

He is not eligible to contribute to an HSA, FYI, unless your plan is also a qualifying HDHP.

>To be an eligible individual and qualify for an HSA contribution, you must meet the following requirements.

I think it depends on coordination of benefits rules, but generally his own employer plan would be primary. Worth confirming with both insurers though.
As others are pointing out, there are two issues here:
– Under Coordination of Benefits (COB) rules, your husband’s employer insurance is primary coverage, while his dependent coverage through your employer is secondary coverage.
If he’s been submitting medical claims solely through his dependent coverage plan, there is likely a day of pain coming where the insurance company learns what happened and retroactively denies all previous claims.
– If the husband’s dependent coverage through your employer is non-HDHP then he (and his employer) is ineligible to make HSA contributions.
A day of pain is coming here as he’s required to remove all offending contributions (and gains, if invested) from the account. They are subject to both income and penalty (technically, it’s an excise tax).
You can’t contribute to a HSA if you are also covered by a non HDHP plan. His plan should have been primary and your plan as secondary. He can be penalized for any funds he contributed to a HSA while being covered by another plan. You have to withdraw the funds from HSA and pay the 6% penalty. It accrues annually until you withdraw the funds. If you do this by 4/15 to avoid additional penalties.
I am on a HDHP with HSA. Let me just pile on to say that when I signed up it was VERY CLEAR that I or my family couldn’t be on another non HDHP to qualify for the HSA. This wasn’t some fine print.
