How to pay a Labcorp bill

Labcorp accepts payments through their online patient portal, by phone, by mail, or in person at a local lab. The fastest method is the online portal — you can pay when ready with a debit card, credit card, or bank account. If you do not have online access, calling Labcorp's billing department at 1-800-845-6167 lets you pay by phone in a few minutes.

Before you pay, have your bill or invoice number ready. You will also need the payment method you want to use: a debit or credit card, or your bank account and routing number if paying by electronic transfer. Labcorp does not charge a fee to pay online or by phone.

Key Takeaways

  • Labcorp's online patient portal is the fastest way to pay — you can complete payment in minutes with a debit card, credit card, or bank account.
  • You can call Labcorp billing at 1-800-845-6167 to pay by phone during business hours, typically Monday through Friday 8 a.m. to 8 p.m. Eastern time.
  • Mailing a check to Labcorp takes longer but works if you do not have online or phone access — your bill shows the mailing address.
  • Payments made online or by phone usually post to your account within one to two business days.

Paying through the Labcorp patient portal

The Labcorp patient portal is the most direct route. Go to labcorp.com, select "Patient Login" at the top of the page, and sign in with your username and password. If you have not created an account, you will need to register first using your name, date of birth, and the phone number or email associated with your Labcorp account.

Once logged in, look for "Billing" or "Pay My Bill" in the menu. Select the bill you want to pay, review the amount, and choose your payment method. Labcorp accepts Visa, Mastercard, American Express, Discover, and direct bank transfers. Enter your payment details, confirm the amount, and submit. You will receive a confirmation number when ready.

If you cannot find your bill in the portal, it may not have been posted yet. Labcorp typically uploads bills within a few days of your test. You can also call billing to confirm the amount owed and get your invoice number.

Paying by phone

Call Labcorp's billing department at 1-800-845-6167. A representative will ask for your name, date of birth, and account or invoice number to locate your bill. Have your payment method ready — a debit card, credit card, or bank account information.

The representative will confirm the amount owed, process your payment, and give you a confirmation number. Keep this number for your records. Phone payments typically post within one to two business days, the same as online payments.

Paying by mail

If you prefer to mail a check or money order, your bill includes a payment stub with the mailing address and your account number. Write your account number on the check or money order, include the payment stub, and mail it to the address shown. Do not send cash through the mail.

Mailed payments take longer to process — typically five to ten business days from the time Labcorp receives it. If your payment is urgent or you are close to a due date, use the online portal or phone instead.

Paying in person at a Labcorp location

You can walk into any Labcorp Patient Service Center and pay your bill in person with cash, debit card, or credit card. Find your nearest location at labcorp.com/locations. Bring your bill or invoice number and a valid ID.

In-person payments are processed when ready, so your account will reflect the payment the same day. This option works well if you are already at a lab for a test or if you live near a Labcorp location.

What to do if you cannot pay the full amount

If you owe money but cannot pay it all at once, contact Labcorp billing at 1-800-845-6167 to discuss a payment plan. Labcorp may allow you to split the bill into smaller monthly payments. The representative will explain what amounts and timeframes are available based on your total balance.

Setting up a payment plan before your bill becomes overdue keeps it from going to a collection agency. If your bill has already been sent to collections, you will need to contact the collection agency directly — Labcorp billing can tell you which one has your account.

Understanding your Labcorp bill

Your Labcorp bill shows the tests you had done, the amount your insurance paid (if you have insurance), and what you owe. The bill lists each test separately with its cost. If you had multiple tests, you may see several line items.

If you have insurance, Labcorp bills your insurance first. What you owe is your patient responsibility — usually your copay, coinsurance, or deductible. If you do not have insurance, you owe the full test cost. If you think your bill is wrong, call billing to ask them to review the charges before you pay.

Frequently Asked Questions

Can I set up automatic payments with Labcorp?

Labcorp does not offer automatic recurring payments through their portal. You can set up a one-time payment or a payment plan, but you will need to make each payment manually. Some credit card companies let you set up automatic bill pay from your card to Labcorp if you have the billing address.

What if I do not have an online account yet?

Go to labcorp.com and select "Register" to create an account. You will need your name, date of birth, and either the phone number or email address Labcorp has on file. Once registered, you can log in and pay your bill. If you cannot register, call 1-800-845-6167 and a representative can help.

How long does it take for my payment to show up?

Online and phone payments usually post within one to two business days. Mailed payments take five to ten business days from the date Labcorp receives them. In-person payments show up the same day. If your payment does not appear after this timeframe, call billing with your confirmation number.

What if I paid but still got a bill?

Your payment may not have posted yet — wait one to two business days and check your account again. If you paid more than a week ago and still see a balance, call 1-800-845-6167 with your confirmation number so billing can investigate.

Can I dispute a charge on my Labcorp bill?

Yes. Call Labcorp billing at 1-800-845-6167 and explain which charge you think is wrong. They will review it and either correct it or explain why the charge is accurate. If you paid by credit card and disagree with their explanation, you can also dispute the charge with your credit card company.
