I woke up on a Tuesday morning in August feeling like I'd swallowed a sock full of thumbtacks. I had a fever, and when I looked at the back of my throat with my phone flashlight, there were white spots. I emailed my supervisor that I was out sick, put on a sweatshirt even though it was humid outside, and drove to an urgent care on Dempster Street when it opened.
This was my first time actually using my high-deductible health plan for something that wasn't a checkup. I picked that plan last November, right before turning 26, because the premium was much cheaper than the PPO and I'm usually healthy. Strep throat was my first real test of that choice.
What happened at urgent care
The visit took about forty minutes. A nurse practitioner looked at my throat, ran a rapid strep test, and came back ten minutes later to say it was positive. She sent a prescription for an antibiotic to a pharmacy near my apartment, told me to drink a lot of water, and said I'd be contagious until I'd been on the medicine for a while. I went home, slept on the couch for most of the day, and felt mostly human by Thursday.
Before I left, the front desk asked for my insurance card and my HSA card. I hadn't used the HSA card once since it arrived.
The $164 bill
Here's what I paid:
- Urgent care visit: $118
- Rapid strep test: $28
- Antibiotics, the generic version: $18
That's $118 + $28 + $18 = $164, all of it from my HSA.
On my plan, I haven't come anywhere near my $3,200 deductible this year, so I paid for all of this myself. But what I paid was the plan's negotiated rate, not the full price. When the explanation of benefits showed up a week later, the urgent care's original charge for the visit and the test was more than double what I owed. The plan doesn't pay much before the deductible, but its network discount still did real work.
Preventive care, like my annual physical, is covered on my plan before the deductible. A sick visit isn't. I knew that in theory. Now I know it in dollars.
My HSA gets $50 from every paycheck before tax, and my employer puts in $500 a year. Since December, it had built up to a little over $1,400. After the strep visit, it's at about $1,250 and still growing every two weeks.
Paying with the HSA card felt different from paying with my checking account, and it took me a minute to figure out why. This money was already set aside for exactly this. My grocery budget didn't change, and my emergency fund wasn't touched. The $164 came out of a bucket that exists so a sore throat stays a sore throat and doesn't turn into a budget problem.
I kept the receipt and the explanation of benefits, both as PDFs in my folder, in case I ever need to show the money went to a qualified medical expense.
Was the high-deductible plan still the right call?
I did the math, because of course I did. On the PPO, the same visit would probably have been a copay, maybe $50 to $75, plus something for the medicine. So in this one week, the PPO would have saved me roughly $100.
But I've also been paying $52 a paycheck instead of $121 since December. Over 18 paychecks, that's 18 × $69 = $1,242 less in premiums so far. One strep visit doesn't come close to erasing that. If I had a big medical year, the math would look different, and I still keep my emergency fund around for exactly that. For a normal year with one surprise, it still works for me.
I want to be clear that this is just my situation. I'm healthy, I don't have regular prescriptions, and I have savings behind me. Someone with a chronic condition or a family to cover might find the opposite answer, and that would be the right answer for them.
A few things I'd tell my past self. Find your urgent care before you need it, so you're not looking up whether it's in network with a fever of 101. Keep your HSA card in your wallet, not in the drawer with takeout menus. And when you get the explanation of benefits, actually open it. It's the one piece of mail that shows what the plan is doing for you, even when you're the one paying.
My mom texted every three hours asking if I needed soup. I didn't, but I said yes anyway. She drove it down from Wilmette and left it outside my door.
