How to Pay Your Labcorp Bill Online, by Phone, or Mail

Where and how to pay Labcorp

Labcorp accepts bill payments through their online patient portal, by phone, by mail, and in person at local collection sites. The fastest route is the online portal if you have an account — you can pay when ready with a debit card, credit card, or bank account. If you do not have online access or prefer to speak with someone, you can call Labcorp's billing department or mail a check to the address printed on your bill.

Your bill will show which payment methods are accepted and may list a specific mailing address for payments. Some bills also include a payment stub with a barcode that speeds processing if you pay by mail. The method you choose does not affect how long payment takes to post to your account, though online and phone payments typically show within one to three business days.

Key Takeaways

  • Labcorp's online patient portal is the fastest way to pay — you can submit payment when ready with a debit card, credit card, or bank account.
  • Phone payments go to Labcorp's billing department and require your account number and payment method information.
  • Mailed payments should include your account number or payment stub and be sent to the address on your bill to avoid delays.
  • Payments typically post within one to three business days regardless of the method you choose.

Paying through the Labcorp online portal

To pay online, log into your Labcorp patient account at labcorp.com or through the Labcorp mobile app. If you do not have an account, you can create one using your email address and a password. Once logged in, look for a "Pay Bill" or "Billing" section in the menu — this location varies slightly depending on whether you are using the website or app.

Select the bill you want to pay, review the amount due, and enter your payment method. Labcorp accepts Visa, Mastercard, American Express, Discover, and bank account transfers (ACH). After you submit the payment, you will receive a confirmation number on screen and by email. Keep this number for your records in case you need to reference the transaction later.

If you cannot find your bill in the portal or do not see a payment option, your account may not be fully set up yet. Contact Labcorp's patient services line to confirm your account is active and linked to your test results and billing information.

Paying Labcorp by phone

Call Labcorp's billing department at the number printed on your bill. Have your account number, the bill amount, and your payment method ready before you call. The representative will walk you through the payment process and confirm the amount and due date.

Labcorp accepts credit cards, debit cards, and bank account information over the phone. The call typically takes five to ten minutes. After payment is processed, you will receive a confirmation number — write this down or ask the representative to email it to you.

Wait times to reach billing can vary depending on the time of day and day of the week. Calling early in the morning or mid-week often means shorter hold times than calling late afternoon or on Fridays.

Paying Labcorp by mail

Write a check or money order payable to Labcorp and include your account number on the check itself. Place the payment stub from your bill in the envelope if one was included — this helps the payment post faster. Mail your payment to the address printed on your bill.

Mailed payments typically take seven to ten business days to arrive and post to your account. To avoid late fees, mail your payment at least two weeks before the due date. If your bill does not include a mailing address, call Labcorp's billing department to confirm where to send payment.

Keep a copy of your check or a photo of the front and back for your records. If your payment does not post within two weeks of mailing, contact Labcorp with your check number and the date you mailed it.

Paying at a Labcorp collection site

Some Labcorp collection sites accept cash or check payments in person. Call your local collection site directly to confirm whether they take bill payments and what hours they are open. Not all locations offer this service, so calling ahead prevents a wasted trip.

If you pay in person, bring your bill or account number and a valid form of identification. Ask for a receipt showing the payment amount and date. In-person payments typically post to your account within one to two business days.

What to do if you cannot pay the full amount

If you owe money but cannot pay the full bill at once, contact Labcorp's billing department to discuss your options. Some situations may allow for a payment plan, though this depends on the amount owed and Labcorp's policies at the time you call. Labcorp may also refer you to a third-party billing company if your account is significantly past due.

Paying even a partial amount shows good faith and may help you avoid collection action. Do not ignore the bill — contacting Labcorp proactively gives you more options than waiting for the account to be referred to collections.

Frequently Asked Questions

Can I pay my Labcorp bill with a credit card online?

How do I know if my payment went through?

You will receive a confirmation number when ready after paying online or by phone. Check your email for a receipt, and log back into your account after one to three business days to confirm the payment posted. If you do not see it posted after three days, contact Labcorp's billing department with your confirmation number.

Payments take one to three business days to post. If more than three days have passed and the bill still shows as due, call Labcorp with your confirmation number and the date you paid. There may be a processing delay or a system error that needs to be corrected.

Can I set up automatic payments with Labcorp?

Some patient portals allow you to set up recurring payments, though this varies by account type. Log into your portal and look for a "Recurring Payment" or "Auto Pay" option, or call billing to ask whether this is available for your account.

Is there a fee to pay my Labcorp bill online?

Labcorp does not charge a fee for online payments made through their portal. Credit card companies or your bank may charge their own fees depending on your account type, so check with them if you have questions about charges.
