Beware medical credit cards and loans

The situation: You need a mole removed. Or a root canal. Or a hearing test. Or something lifesaving, like cancer treatment.

A big scary bill is looming on the horizon, and you don’t think your insurance is going to protect you.

But your provider has a solution: signing you up for a medical credit card, like CareCredit or HealthiPlan, or a loan from a third party financing company like AccessOne, Scratchpay, CarePayment, or Prosper.

Plans like these have become the default for lots of providers. It keeps them from having to deal with patients who can’t pay upfront.

And it might even sound good to you at first — promising you a 0% interest, no down payment, and no credit check.

But it also sounds a little too convenient, right?

It is. And then some.

Depending on the terms of the deal, as well as medical debt protections in your state, these options can leave you in a much worse position than if you were to receive ongoing bills from a medical provider — even if that provider sics a debt collector on you.

Here’s why you should be on the lookout for medical credit deals that are too good to be true, and why you should exhaust all other options before signing up.

Here’s what you’re forfeiting when you sign up

As soon as you pay your medical bill with a medical credit card or loan, you’re giving up your ability to:

Check your bill for errors
Make sure your insurance is paying what it’s supposed to
Apply for charity care
Negotiate a discount

And depending on the laws in your state, you’re also potentially giving up protections against hits to your credit report, garnishment of your wages, and liens on your home.

Huge interest rates buried in fine print

Here’s one of the biggest financial traps to look out for — especially with medical credit cards: “deferred interest” or “retroactive interest.”

It’s how, as advocates from Community Catalyst breakdown in this video, a bill for a $5,000 medical emergency can turn into a total bill for $6,650 overnight — and keep growing.

Here’s how that works: That zero-interest rate has an expiration date — anywhere from six months to a couple of years after you sign up. If you don’t pay off every cent by that date, a new rate kicks in. A steep one.

CareCredit’s is 32.99%. (The average rate for regular credit cards at the end of 2025 was about 21%.)

And that new rate applies to the entire original amount of the bill — even if you’ve paid off some or nearly all of it.

It’s one thing if you’re absolutely certain you can pay your bill off before the zero-interest period ends. But many people don’t. And you may find late fees and other pitfalls buried in the fine print.

How to avoid these cards and loans

Be vigilant about the forms you’re signing.

Providers could try to shove you into a credit arrangement with one of these “partners” without checking your insurance first, and maybe without you even realizing it.

And – although it’s illegal in at least CA, IL, and NY – they may even try to fill out the forms for you. Don’t let them.

Make absolutely sure you actually owe this amount.

Medical bill errors happen all the time. Insurance companies make mistakes, too. And if you discover one only after you’ve put money down on a card or loan, it can be darn-near impossible to fix the error and adjust your credit balance.

Ask about “charity care” by name.

Most hospitals are legally required to offer this kind of financial assistance to a portion of their patients, and other kinds of medical practices may offer discounts to low-income patients, too.

But Jared Walker, founder of Dollar For, a nonprofit dedicated to helping people get access to charity care, says that providers will steer you towards medical credit products when you ask about “payment plans” versus “charity care.” So be specific.

See if you can negotiate your bill down.

If you have a certain amount of cash ready to pay upfront, see if they’ll settle for that.

Ask for an in-house payment plan instead.

You’re still dealing with medical debt here — but because you owe money directly to the health care provider, rather than a third party, you at least keep those medical debt protections.

Consider other types of loans.

If you’re in dire straits and financial assistance isn’t an option, it might be worth looking into a personal loan from a bank, credit union, or even a friend or family member. Your mileage may vary, but you could stumble on a deal with better terms.

We consistently get our best tips from readers. Also: corrections.

Last week, we dove into what counts as “preventive care” under federal law. We wrote that Medicare covers annual physicals for folks 65+ at no cost. But that wasn’t accurate, and a reader named Daniel corrected us.

In fact, Medicare pays for an annual “wellness” visit — which doesn’t include a physical exam, and is more like a consultation. Thanks, Daniel!

That’s all from us this week. We’ll be back in your inbox next week with a new episode.
