Where to pay your LabCorp bill

LabCorp's billing website is at labcorp.com/billing. You can log in there to view your bill, make a one-time payment, or set up automatic payments. The site accepts credit cards, debit cards, and bank account transfers. You do not need to create an account to pay — you can pay as a guest using your bill number and date of birth.

If you prefer not to pay online, you can mail a check or money order to the address printed on your bill. Include your account number on the check. Mail payments take 7 to 10 business days to reach LabCorp's processing center, so send them early if your due date is approaching.

You can also call LabCorp's billing department at 1-844-LABCORP (1-844-522-2677) to pay over the phone with a credit or debit card. A representative will ask for your bill number and payment amount.

Key Takeaways

  • LabCorp's billing portal at labcorp.com/billing lets you pay online with a card or bank account, and you can pay as a guest without creating an account.
  • You can set up automatic payments through the billing portal so the same amount withdraws on the same day each month.
  • Mailed checks take 7 to 10 business days to process, so send them well before your due date to avoid late fees.
  • Calling 1-844-LABCORP lets you pay by phone with a credit or debit card if you do not want to use the website.
  • Late payments may result in collection activity or impact your credit report, depending on how far past due the bill becomes.

What information you need to pay online

To pay through labcorp.com/billing, have your bill number ready. You can find it at the top of your paper bill or in any email LabCorp sent you about the balance. You will also need your date of birth to verify your identity as a guest payer.

If you are paying from a bank account instead of a card, you will need your routing number and account number. These appear on the bottom left of your checks. The payment will be processed as an ACH transfer, which typically takes one business day to complete.

Setting up automatic payments

If you want the same amount to withdraw automatically each month, log into your account on labcorp.com/billing and select the automatic payment option. You can choose the payment date and amount. LabCorp will send you a confirmation email each time a payment processes.

Automatic payments stop when your balance reaches zero. If your bill amount changes — for example, if you have another test done — you will need to update the payment amount manually or contact billing to adjust it. You can cancel automatic payments at any time through your account settings.

What happens if you miss a payment

If your bill becomes 30 days past due, LabCorp may report the debt to a credit reporting agency. This will appear on your credit report and may lower your credit score. The company may also send your account to a collection agency, which will contact you about the balance.

If you cannot pay the full amount, contact LabCorp's billing department at 1-844-LABCORP to discuss a payment plan. Some accounts may be may be able to access for a plan that spreads the balance over several months. The sooner you contact them, the more options you may have before the account goes to collections.

Understanding your LabCorp bill

Your LabCorp bill shows the tests you had done, the amount your insurance paid (if you have coverage), and the amount you owe. The bill lists each test separately with its own charge. If you do not recognize a test or charge, call the billing department to ask for an explanation before you pay.

Some bills show a balance from a previous visit plus new charges from a recent test. Make sure you understand which charges are new and which are old. If you think a charge is wrong, you can dispute it by calling billing — they can review the test order and your insurance explanation of benefits to confirm the amount.

Payment methods and fees

LabCorp does not charge a fee to pay by bank account transfer (ACH) through their website. Credit and debit card payments through the website also have no fee. However, if you pay by phone with a card, some representatives may mention a convenience fee — ask about this before you complete the payment.

Mailed checks and money orders have no fee. If you use a third-party bill payment service through your bank, check with your bank about whether they charge a fee for sending the payment to LabCorp.

If you cannot find your bill number

Your bill number appears at the top of your paper bill or in the subject line of any email from LabCorp about your account. If you have lost the bill, you can call 1-844-LABCORP and a representative will look up your account using your name, date of birth, and Social Security number or date of service.

You can also create an account on labcorp.com to view all your past and current bills in one place. This makes it easier to track payments and find bill numbers for future reference. Creating an account requires your email address and a password you choose.

Frequently Asked Questions

Can I pay a LabCorp bill without creating an account?

Yes. The guest payment option at labcorp.com/billing lets you pay with just your bill number and date of birth. You do not need to set up a username or password. If you plan to pay multiple times, creating an account saves time because you can view all your bills in one place.

How long does it take for an online payment to show up?

Credit and debit card payments process immediately and show on your account within one business day. Bank account transfers (ACH) take one to two business days. Mailed checks take 7 to 10 business days. If your due date is soon, pay online or by phone to avoid late fees.

What if I paid but my bill still shows a balance?

Online and phone payments take one business day to post to your account. If you paid more than two business days ago and the balance has not changed, call 1-844-LABCORP to confirm the payment was received. Provide the date and amount you paid so they can locate it in their system.

Can I get a payment plan if I cannot pay the full bill at once?

Call 1-844-LABCORP to discuss options. LabCorp may offer a plan that lets you pay the balance over several months, though this depends on the amount owed and your account history. The sooner you contact them, the more likely they are to work with you before sending the account to collections.

Does LabCorp charge interest on unpaid bills?

LabCorp does not typically charge interest on medical bills, but they will report unpaid balances to credit agencies and may send the account to a collection agency. Collection agencies may add fees to the original balance. Paying as soon as possible avoids these additional costs.
