How to Pay Your LabCorp Bill

Where to pay your LabCorp bill depends on how you received it

LabCorp sends bills through the mail or makes them available online through your patient account. The fastest way to pay is through your online account at labcorp.com — you can log in with your date of birth and account number from your bill. If you don't have an online account set up yet, you can create one using the same information.

You can also pay by phone, mail, or in person at a LabCorp patient service center. The method you choose depends on how quickly you need the payment processed and whether you have your bill information handy. Each route has different timing and requirements.

Key Takeaways

• Online payment through your LabCorp account is the fastest method and shows as processed within one business day.
• Phone payments require your bill number and a debit card or bank account, and you can pay by calling the number on your bill.
• Mail payments should include your account number and bill stub, and take 7 to 10 business days to post to your account.
• In-person payments at a LabCorp patient service center are processed when ready and require a photo ID and payment method.

Paying online through your LabCorp account

Log in to your account at labcorp.com using your date of birth and account number. If you don't have an account, select "Create Account" and enter the same information from your bill. Once logged in, look for "Pay My Bill" or "Billing" in the menu — the exact wording varies depending on whether you're on a desktop or mobile device.

Enter the amount you want to pay and choose your payment method: debit card, credit card, or bank account transfer. LabCorp charges a fee for credit card payments but not for debit cards or bank transfers. Review the total before you submit, and you'll receive a confirmation number when ready. The payment typically posts within one business day.

Paying by phone

Call the phone number printed on your bill — this is usually the fastest way to reach the right department. Have your bill number and account number ready, along with either a debit card, credit card, or bank account information. The representative will walk you through the payment and give you a confirmation number.

Phone payments are processed the same day you call if you pay before 5 p.m. Eastern Time on a business day. If you call after hours or on a weekend, your payment will be queued for processing the next business day. Ask the representative how long it typically takes for the payment to show in your account — this varies by payment method.

Paying by mail

Write a check or money order payable to LabCorp. Include your account number and bill stub with your payment, and mail it to the address shown on your bill. Do not send cash through the mail. Use a standard envelope and regular postage — LabCorp does not require certified mail or special handling.

Mail payments take 7 to 10 business days to arrive and be processed. If you're close to a due date, mail is not the best option. Keep a copy of your check or money order number for your records in case you need to track the payment later.

Paying in person at a LabCorp location

Find your nearest LabCorp patient service center using the location finder at labcorp.com. Call ahead to confirm the center accepts bill payments — not all locations do. Bring your bill, a photo ID, and your payment method: cash, check, debit card, or credit card.

In-person payments are processed when ready and you'll receive a receipt on the spot. This is the best option if you need proof of payment the same day or if you prefer to handle the transaction face-to-face. Hours vary by location, so check the website or call before you go.

What to do if you can't pay the full amount

Contact LabCorp's billing department using the phone number on your bill and ask about a payment plan. LabCorp may allow you to split your bill into smaller payments over several months, depending on the total amount owed and your account history. The representative will explain what options are available and whether any fees explore to a payment plan.

If you're having financial hardship, mention this when you call — some programs or discounts may be available depending on your situation. Getting ahead of a past-due balance is better than waiting, because unpaid bills can be sent to a collection agency.

Tracking your payment after you submit it

Log into your online account to see the status of your payment. Online and phone payments usually show as "pending" for one business day, then move to "posted" or "paid." Mail and in-person payments may take longer to appear in the system.

If your payment doesn't show up within the timeframe the representative gave you, call LabCorp billing again with your confirmation number. Have the date and amount of your payment ready. The representative can look up the payment in their system and tell you exactly when it will post to your account.

Frequently Asked Questions

Can I set up automatic payments for my LabCorp bill?

Yes, through your online account. Log in, go to the billing section, and look for "AutoPay" or "Automatic Payments." You can set it to pay your full balance or a set amount each month on a date you choose. You can change or cancel automatic payments anytime through your account.

What if I paid online but my bill still shows as due?

Online payments take one business day to post. If more than one business day has passed, log back into your account and look for the payment status — it should show as "posted" or "paid." If it still shows as due, call the billing number on your bill with your confirmation number and the date you paid.

Do I have to pay the full bill at once?

Not necessarily. You can pay part of your bill now and the rest later, or set up a payment plan by calling LabCorp billing. Partial payments are accepted through all payment methods. Just make sure you pay the full amount before the due date to avoid late fees or collection action.

What happens if my payment is late?

LabCorp may charge a late fee and report the account to a collection agency if the bill remains unpaid. The amount of the late fee and the timeline for collection action vary. Call billing as soon as you know you'll be late — they may waive a fee or work with you on timing if you contact them before the account is sent to collections.

Can I dispute a charge on my LabCorp bill?

Yes. Call the billing number on your bill and explain which charge you're questioning. Have your bill and any related paperwork ready. The representative can review the charge with you and may be able to adjust it if there's an error. If you can't reach an agreement, ask about the formal dispute process.
