My wife and I kept it and didn’t pay out of it. My wife had a C-section and gave birth to twin girls. Our out of pocket was around $2500. Still less than paying a year’s worth of higher premiums.my company offers it but I've avoided opting in because being in a timeframe of life where pregnancy and childbirth can happen means it's not a great option.
i had knee surgery to repair a meniscus tear and an MCL tear. It cost me $2200 out of pocket. I save way more than that in the difference between premiums.
My company also contributes $1000 every year to the HSA. Your HSA can be invested in mutual funds offered by the provider under your fund. You are missing out on that gain. You can reimburse yourself at anytime tax free for bills you paid out of pocket(next day, 6 months 2 years, 20 years, no limit). You could allow your savings to grow for 20 years, then withdraw $20,000 in reimbursement tax free.
At age 65 your benefit can be used like a 401k if you desire.
I view it as another way to invest approximately $7500 a year tax free.
