High deductible plan advice

Ok while I’m not the most savvy on earth with health insurance ins and outs, I’m not the worst. This is a gut check post to make sure I’m not missing any potential considerations. Including health profiles as that matters.

Husband – type 1 diabetic requiring normal amount of diabetic care and supplies. He will get a new insulin pump in 2023 when new plan is in place.

Me- healthy ish but gets treated by nueorlogist for migraines and planning to get pregnant in 2023.

He was paying in premiums for his works plan the same cost as what the deductible is for the high deductible plan at my work.

For my work’s high deductible plan, there are no premiums and no cost for anything once the deductible is met. We will also contribute to the hsa and my employer does a contribution too. Also notable that the out of pocket max is lower than my other work plan option or his works plan.

So I told him if he comes on my work plan, he will pay his medical costs for prescription, office visits, insulin and pump until he meets the deductible and he will do so with the hsa funds we contribute. After that it’s free. So assuming he hits the deductible before he has to buy a new insulin pump, for instance, the pump is free.

For me, I will pay my treatment and medication costs and specialty office visits out of pocket until meeting the deductible and then everything is free including the delivery of my child and genetic testing etc assuming I hit deductible before then with my migraine stuff.

What am I missing? Anything nuanced or major?
