What Mayo Bill Pay is and how to use it

Mayo Bill Pay is the online payment system Mayo Clinic uses to let patients pay medical bills through their patient portal. You log in with your Mayo Clinic account, enter the amount you want to pay, and choose to pay by bank transfer, debit card, or credit card. The system processes most payments the same day or next business day.

To use it, you need a Mayo Clinic patient account set up first. If you don't have one, you can create it on the Mayo Clinic website using your Social Security number, date of birth, and a recent medical record number from a bill or appointment letter. Once you're logged in, look for the "Pay My Bill" or "Billing" section in your portal — the exact name varies slightly by location.

Mayo Clinic operates in Minnesota, Wisconsin, Iowa, Arizona, and Florida, and each location's portal works the same way. If you received a bill in the mail, it will have an account number and a link to the portal printed on it.

Key Takeaways

  • Mayo Bill Pay lets you pay from your computer or phone without calling or mailing a check, and most payments post within one business day.
  • You can pay with a bank account (no fee), debit card (small fee), or credit card (higher fee), so the cost depends on which method you choose.
  • If you cannot pay the full balance, you can set up a payment plan directly through the portal or by calling the billing department.
  • Payments made after 5 p.m. local time or on weekends usually post the next business day, so timing matters if you're close to a due date.
  • If you lose access to your portal or forget your password, the billing phone number on your statement can reset it or take a payment over the phone.

Payment methods and what each one costs

Bank account transfer (also called ACH or electronic check) costs nothing and is the cheapest option. The money comes directly from your checking or savings account. You'll need your routing number and account number, which you can find at the bottom of any check. This method takes one to three business days to clear, so plan ahead if you're near a due date.

Debit card payments usually cost between $0.50 and $2.50 per transaction, depending on your card issuer and Mayo's processing agreement. The payment posts immediately or within one business day. Credit card payments cost more — typically 2 to 3 percent of the amount you're paying — because credit card networks charge higher processing fees. A $500 credit card payment might cost $10 to $15 in fees.

If you're paying a large bill, the fee difference matters. A $2,000 payment costs nothing by bank account, $2 to $5 by debit card, or $40 to $60 by credit card. The portal will show you the fee before you confirm the payment, so you can decide whether to use a different method.

Setting up a payment plan if you can't pay in full

If your bill is large and you can't pay it all at once, Mayo Clinic offers payment plans through the portal or by phone. You can usually set up a plan for balances over $200, though the exact threshold varies by location. The plan lets you split the bill into monthly payments over three to twelve months.

Payment plans through Mayo do not charge interest, but they do require you to make payments on time each month. If you miss a payment, the plan may be cancelled and the full balance could become due. You can set up automatic payments from your bank account to avoid missing a due date.

To set up a plan, log into your portal and look for "Payment Plans" or "Financing Options," or call the billing number on your statement. The phone line can usually set one up in a few minutes. You'll need to confirm your income or employment to show you can afford the monthly amount.

What happens if you miss a payment or fall behind

If a payment is late, Mayo Clinic will send you a notice in the mail. The first notice usually comes 30 days after the due date and asks you to pay within 10 days. If you don't respond, you'll receive a second notice around 60 days past due, and a third around 90 days past due.

After 120 days, Mayo may send your account to a collection agency or file a lawsuit to recover the debt. At that point, the debt collector, not Mayo, will contact you. A judgment against you can lead to wage garnishment or bank account levies in some states. If you receive a collection notice, respond to it — ignoring it makes the situation worse.

If you're having trouble paying, contact Mayo's billing department before you fall behind. They can discuss a payment plan, a temporary pause, or financial hardship programs that may reduce what you owe. Many hospitals have charity care or financial assistance programs for patients below certain income thresholds, and Mayo is no exception.

How to find your account number and access your bill online

Your account number appears on every bill Mayo sends you — it's usually near the top or bottom of the first page, sometimes labeled "Account Number," "Patient Account," or "MRN" (medical record number). You'll need this number to log into the portal or to pay by phone.

To access your bill online, go to the Mayo Clinic patient portal website for your state (Minnesota, Wisconsin, Iowa, Arizona, or Florida each have their own portal). Sign in with your username and password. If you don't have a portal account yet, select "Create Account" and enter your Social Security number, date of birth, and the account number from your bill.

Once you're logged in, look for a "Billing" or "Statements" tab. You'll see all bills sent to you in the past, usually going back two to three years. You can view the full bill as a PDF, see what charges are included, and check which parts have been paid.

Paying by mail or phone if you don't want to use the portal

If you prefer not to pay online, you can mail a check to the address printed on your bill. Write your account number on the check and mail it to the billing address listed. Mail typically takes five to seven business days to arrive, so send it at least a week before the due date to avoid a late payment.

You can also pay by phone by calling the billing number on your statement. A representative will take your payment information over the phone — either a bank account, debit card, or credit card. Phone payments are processed the same day if you call before 5 p.m. local time on a business day. The same fees apply: nothing for bank account, a small fee for debit card, and a percentage fee for credit card.

Some people worry about giving their bank details over the phone. If that concerns you, use the online portal instead — it's encrypted and more secure than a phone call. If you do call, make sure you initiated the call using the number on your bill, not a number from an email or text, to avoid scams.

Understanding your Mayo Clinic bill and what charges mean

Mayo bills can be confusing because they list charges by department, procedure, or service code rather than in plain language. A charge labeled "99213" is an office visit; "70450" is a CT scan of the head. If you don't recognize a charge, call the billing number and ask what it is — they can explain it and tell you which doctor or department ordered it.

Your bill will also show what your insurance paid (if you have insurance) and what you owe. The amount you owe is your responsibility — this includes your deductible, copay, coinsurance, and any charges your insurance didn't cover. If you think a charge is wrong or shouldn't be there, ask for an itemized bill and a copy of your medical record. You have the right to see what you were charged for.

If you received multiple bills from different Mayo departments or locations, each one has its own account number and due date. You can pay them separately through the portal or ask the billing department to consolidate them into one bill.

Frequently Asked Questions

Can I set up automatic payments through Mayo Bill Pay?

Yes. Once you log in, you can usually set up recurring payments for a fixed amount on a date you choose each month. This works best if you have a payment plan. You can change or cancel automatic payments anytime through the portal.

What if I don't have internet access or can't use the portal?

Call the billing number on your statement. A representative can take your payment over the phone, reset your portal password, or mail you a paper bill with a return envelope. Some locations also accept payments in person at the hospital or clinic.

Does paying by credit card build my credit score?

Medical bills paid through a hospital's payment system do not report to credit bureaus, so paying your Mayo bill won't help your credit score. However, if the bill goes to a collection agency, it will hurt your score. Paying on time keeps it out of collections.

Can I dispute a charge on my Mayo bill?

Yes. Call the billing department and explain which charge you dispute. Ask for an itemized bill and documentation of what was done. If you think the charge is a billing error, they can investigate. If you think the service itself was wrong, you may need to contact the doctor or file a complaint with your state's health department.

What if I'm on a payment plan and can't make a payment?

Contact Mayo's billing department immediately. Explain your situation and ask if they can pause the plan, lower the monthly amount, or extend the timeline. Missing a payment without calling can result in the plan being cancelled and the full balance becoming due.
