Labcorp bills you after lab work is done, not before

Labcorp sends an invoice after your test results are processed. You will not pay at the lab itself unless you are uninsured and choose to pay upfront. The bill arrives by mail or email, depending on your account settings, and includes the test name, the amount owed, and payment instructions. If insurance covered part of the cost, your bill shows what your insurance paid and what you owe as your share.

The amount you owe depends on whether you have insurance, what your plan covers, and whether you went to an in-network or out-of-network Labcorp location. If you are uninsured, Labcorp offers a cash price that is often lower than the insurance rate. You can ask about the cash price before the test or after you receive the bill.

Key Takeaways

  • Labcorp bills after your test is complete, and you can pay online, by phone, by mail, or in person at a Labcorp location.
  • Online payment through your Labcorp account is the fastest method and lets you see your full bill history and insurance details.
  • If you cannot pay the full amount, Labcorp offers payment plans with no interest for balances over a certain threshold, though terms vary by location.
  • Uninsured patients can ask about cash prices, which are often lower than standard rates and may be discounted further if you pay upfront.
  • If your bill includes charges you do not recognize or believe are wrong, contact Labcorp billing to dispute the charge before paying.

Paying online through your Labcorp account

The fastest way to pay is through the Labcorp website or mobile app. Go to labcorp.com, select "Pay My Bill," and log in with your account credentials. If you do not have an account, you can create one using your date of birth and the account number from your bill. Once logged in, you will see all outstanding balances, the date each bill is due, and a breakdown of what insurance paid versus what you owe.

Click the bill you want to pay and choose your payment method: debit card, credit card, or bank account transfer. Debit and credit card payments process immediately. Bank account transfers (ACH) take one to three business days. Labcorp does not charge a fee for any of these methods. You will receive a confirmation number and a receipt by email.

Paying by phone or mail

Call Labcorp's billing department at 1-800-LAB-CORP (1-800-522-2677) to pay by phone with a debit card, credit card, or bank account information. A representative will pull up your account, confirm the amount due, and process the payment. This method works if you do not have internet access or prefer to speak with someone. Phone payments process the same day if you call before 5 p.m. Eastern time.

To pay by mail, write a check or money order payable to Labcorp and include your account number on the check. Mail it to the address printed on your bill. Mail payments take seven to ten business days to reach Labcorp and be posted to your account. Include a copy of your bill or write your account number on the envelope so the payment is matched to the right account.

Paying in person at a Labcorp location

You can walk into any Labcorp patient service center and pay your bill in cash, by debit card, or by credit card. Ask the front desk staff to help you pay an existing bill. They will look up your account and process the payment on the spot. This method is useful if you prefer to handle it face-to-face or do not have online or phone access.

Not all locations accept payments at the front desk during all hours, so call ahead to confirm. Use the Labcorp location finder on their website to get the phone number and hours for the center nearest you.

Setting up a payment plan if you cannot pay in full

Labcorp offers payment plans for balances above a certain amount, though the threshold varies by location and the total bill. Payment plans typically have no interest and allow you to split the bill into two to four equal monthly payments. To set up a plan, call 1-800-LAB-CORP and ask about payment plan options for your account. A representative will tell you whether your balance qualifies and what the monthly payment would be.

Some Labcorp locations also work with third-party financing companies that offer longer payment terms with interest. These are optional and should be considered only if monthly payments through Labcorp are not affordable. Always ask about the interest rate and total cost before agreeing to third-party financing.

Understanding your bill and disputing charges

Your Labcorp bill lists each test performed, the charge for that test, and how much your insurance paid. If you see a charge you do not recognize or believe is incorrect, contact Labcorp billing before paying. Explain which charge you are questioning and why. Labcorp will review the charge and either correct it or explain why it is accurate.

Common reasons for unexpected charges include tests your doctor ordered but you did not know about, tests not covered by your insurance plan, or out-of-network facility fees. If your insurance should have covered a test but did not, ask Labcorp to resubmit the claim to your insurance company. If you believe the charge is truly an error, request an itemized bill that shows exactly what was tested and why.

What to do if you receive a collection notice

If your bill goes unpaid for several months, Labcorp may send it to a collection agency. At that point, the collection agency, not Labcorp, owns the debt and will contact you to collect. Collection accounts damage your credit score and make it harder to borrow money in the future. If you receive a collection notice, contact the collection agency immediately to discuss payment options or a settlement.

If you believe the debt is not yours or the amount is wrong, you have the right to dispute it in writing within 30 days of receiving the notice. Send your dispute to the collection agency by certified mail and keep a copy for your records. The agency must stop collection efforts while investigating your dispute.

Frequently Asked Questions

Can I pay my Labcorp bill before I get the invoice?

No. Labcorp bills after your test is processed, which usually takes one to three business days. You cannot pay in advance. If you want to know the cost before the test, ask Labcorp or your doctor for an estimate based on the test code.

Does Labcorp charge a fee to pay online or by phone?

No. Labcorp does not charge a processing fee for online payments, phone payments, or mail payments. Credit card companies or your bank may charge their own fees, but Labcorp does not add anything on top.

What if I lost my bill or do not know my account number?

Log into your Labcorp account online using your date of birth and the phone number or email associated with your account. Your account number and all bills will appear there. If you cannot remember your login details, use the "Forgot Password" link on the Labcorp website to reset it.

Will my insurance cover the full cost of my test?

That depends on your specific plan. Your bill will show what your insurance paid and what you owe. If you think your insurance should have covered more, contact your insurance company to ask why the claim was denied or only partially paid. Labcorp can also resubmit the claim if you believe it was submitted incorrectly.

Can I negotiate or reduce my bill if I am uninsured?

Yes. Uninsured patients should ask Labcorp about cash prices, which are often lower than standard rates. Some locations offer further discounts if you pay upfront. Call 1-800-LAB-CORP and ask about uninsured pricing for your specific test before or after you receive the bill.
