Quest Diagnostics bills you after your lab work is complete

Quest Diagnostics sends a bill to the address on file after your lab results are processed. You can pay that bill through their online portal at questdiagnostics.com/bill, by phone, by mail, or in person at a Quest location. The online method is fastest — you can pay in minutes from your computer or phone without waiting on hold.

Your bill arrives separately from your lab results. If you had insurance, Quest bills your insurance first, then sends you a statement for any remaining balance. If you paid out of pocket, the full amount appears on your bill. Either way, the payment portal works the same way.

Key Takeaways

  • You can pay your Quest bill online at questdiagnostics.com/bill using a debit card, credit card, or bank account.
  • The online portal asks for your account number (on your bill) or your date of birth and Social Security number to locate your account.
  • Payments made online typically post within one business day, though the portal may show confirmation immediately.
  • If you cannot pay the full amount, Quest offers payment plans for balances over a certain threshold — contact their billing department to set one up.
  • Paying online does not require you to create an account or log in; you can pay as a guest using your bill information.

What information you need to pay online

Gather your Quest bill before you go to questdiagnostics.com/bill. You will need either your account number (printed on the bill) or your date of birth and Social Security number. The portal uses one of these to pull up your account and show what you owe.

Have your payment method ready: a debit card, credit card, or bank account information. The portal accepts all three. If you are paying from a bank account, you will need your routing number and account number, which you can find at the bottom of a check or in your online banking portal.

Steps to pay through the online portal

Go to questdiagnostics.com/bill in your web browser. The page will show a payment form. Enter either your account number or your date of birth and last four digits of your Social Security number, then click the button to find your account.

The portal will display your balance and any recent charges. Review the amount to make sure it matches your bill. Select your payment method — card or bank account — and enter the details. Choose how much you want to pay (the full balance or a partial amount). Enter your email address so Quest can send you a receipt.

Review the information one more time, then submit. The portal will show a confirmation number immediately. Write it down or take a screenshot. Quest will send a receipt to your email within a few minutes.

What happens after you pay online

Your payment shows as received in the Quest portal within minutes, but it may take one business day to post to your account. During that time, the money is in transit from your bank or card company to Quest. Once it posts, your balance updates and you will not see a past-due notice.

If you paid by bank account, the funds typically leave your account within one to two business days. If you paid by debit or credit card, the charge appears on your statement within one to three business days depending on your bank.

Payment plans if you cannot pay in full

Quest offers payment arrangements for balances above a certain amount, which varies by location and situation. You cannot set up a payment plan through the online portal — you have to contact Quest's billing department by phone or mail to arrange one.

Call the number on your bill to speak with a representative. Tell them you want to set up a payment plan. They will ask about your balance and what you can afford to pay each month. Once you agree on a schedule, they will confirm it in writing. You can then make monthly payments online, by phone, or by mail according to that schedule.

Paying by phone or mail if you prefer not to use the portal

The phone number for Quest billing is on your bill. Call and provide your account number. A representative will take your payment information over the phone. This method takes longer than the online portal but does not require you to enter card details into a website.

To pay by mail, write a check or money order payable to Quest Diagnostics. Include your account number on the check. Mail it to the address shown on your bill. Payments by mail take seven to ten business days to reach Quest and post to your account, so send it early if you have a due date approaching.

What to do if you cannot find your bill or account

If you lost your bill, you can still pay online using your date of birth and Social Security number instead of your account number. The portal will search for accounts under that name and show you what is owed.

If the portal does not find your account, call the number on any previous Quest paperwork or search your email for a bill from Quest. If you still cannot locate it, call Quest's main customer service line — the number is on their website — and ask for the billing department. They can look up your account by name and date of birth and tell you what you owe.

Frequently Asked Questions

Is there a fee to pay online at questdiagnostics.com/bill?

No. Quest does not charge a fee for paying through their online portal. You pay only the amount on your bill, with no additional processing charge.

Can I pay someone else's Quest bill through the portal?

You can if you have their account number or their date of birth and Social Security number. The portal does not verify who is making the payment, only that the account information is correct. If you are paying for a family member or dependent, you can use their information to locate and pay their bill.

What if my payment was rejected?

The portal will show an error message explaining why — usually an incorrect card number, expired card, insufficient funds, or a mismatch between the address on file and the address you entered. Check your card details and try again. If the problem persists, call the number on your bill and pay by phone instead.

How long does it take to get a receipt after I pay online?

The portal shows a confirmation number immediately after you submit payment. Quest sends an email receipt within a few minutes to the address you provided. Keep both for your records.

Can I set up automatic payments through the portal?

The online portal at questdiagnostics.com/bill does not offer automatic recurring payments. You have to pay each bill manually. If you want automatic payments, call Quest's billing department and ask about setting up autopay through their account management system.
