Quest Bill Pay lets you pay your lab test bill directly to Quest Diagnostics through their online portal or by phone, but the method you use and the timing matter for your account
Quest Diagnostics operates a bill payment system called Quest Bill Pay that processes payments for lab work you've had done. You can pay online through your Quest patient account, by phone with a representative, or by mail. The payment goes directly to Quest, not through a third-party processor, which means the money reaches your account faster than some other payment methods.
The real question most people have is whether paying through Quest Bill Pay affects your credit report or what happens if you can't pay the full amount right away. The answer depends on whether your bill has already been sent to a collection agency and whether Quest offers a payment plan for your specific situation.
Key Takeaways
- Quest Bill Pay processes payments through Quest's own system, so your payment arrives the same or next business day rather than taking several days to clear.
- If your bill is still with Quest (not yet sent to collections), you can ask about payment plans or financial hardship options when you call to pay.
- Paying through Quest Bill Pay does not report to credit bureaus as a positive payment, but it does stop the bill from aging further toward collections.
- If your bill has already been sent to a collection agency, paying Quest directly may not stop collection calls, and you should confirm the debt is still with Quest before sending money.
How to pay your Quest bill online or by phone
To pay online, log into your Quest patient account at questdiagnostics.com using your username and password. If you don't have an account, you can create one with your date of birth and Social Security number. Once logged in, look for "Billing" or "Pay My Bill" in the account menu. You'll enter your payment amount and choose a payment method—debit card, credit card, or bank account transfer.
To pay by phone, call Quest's billing department at the number on your bill. A representative will verify your identity and process the payment over the phone. This route is slower if you're in a hurry because you have to wait for someone to answer, but it's useful if you want to discuss a payment plan or ask about financial hardship programs before you pay.
Payments made online before 11:59 p.m. Eastern Time typically post to your account the next business day. Payments made by phone may take one to two business days depending on when you call and what payment method you use.
What happens if you can't pay the full amount
Quest does not automatically offer payment plans for all bills. Whether a plan is available depends on the amount owed and your account history. The only way to find out is to call the billing number on your statement and ask. If a plan is available, Quest will usually allow you to split the bill into two to four payments over 30 to 90 days, depending on the total amount.
If you cannot pay and do not arrange a plan, your bill will age. After 30 days unpaid, Quest may flag your account as past due. After 60 to 90 days, the bill may be sent to a third-party collection agency. Once that happens, paying Quest directly will not stop the collection agency from calling you, because the debt is no longer Quest's responsibility—it belongs to the collector.
If you think your bill is incorrect, you can dispute it before paying. Contact Quest's patient advocate or billing department and explain what you believe is wrong. This does not stop the bill from aging, but it does create a record that you contested the charge.
The difference between paying Quest and paying a collection agency
If your bill has been sent to collections, you have two separate debts in the system: one with Quest (which they've written off) and one with the collection agency (which now owns the right to collect from you). Paying Quest will not satisfy the collection agency's claim, and the agency can continue to pursue you legally.
Before you send any money, confirm who currently owns the debt. If your bill is still with Quest, the statement will say so. If it's been sent to collections, you'll receive a letter from the collection agency with their contact information and the amount they claim you owe. Call the number on that letter, not Quest, to settle the debt.
If you're unsure, call Quest's billing department and ask directly: "Is this bill still with Quest, or has it been sent to a collection agency?" They will tell you. If it's in collections, ask Quest for the name and phone number of the agency so you can contact them to negotiate.
How Quest Bill Pay affects your credit report
Paying your Quest bill through Quest Bill Pay does not report to the three major credit bureaus (Equifax, Experian, and TransUnion) as a positive payment. This means paying on time will not help your credit score. However, if your bill goes unpaid and is sent to collections, that collection account will appear on your credit report and will lower your score.
The longer your bill sits unpaid, the more damage it does to your credit. A bill that is 30 days past due may not yet be reported to credit bureaus, but a bill that is 60 to 90 days past due usually will be. Once it's reported, it stays on your credit report for seven years from the date of first delinquency, even if you pay it later.
If you pay the bill before it goes to collections, it will not appear on your credit report at all. This is why paying as soon as you can, even if it's not the full amount, is better than waiting.
What to do if you receive a collection notice for a Quest bill
If you receive a letter from a collection agency about a Quest bill, do not ignore it. The agency has the legal right to sue you if the debt is old enough and your state allows it. The time limit varies by state—typically three to six years—but the clock starts from the date you last made a payment or acknowledged the debt.
Call the collection agency's number on the letter and ask for a debt verification letter. Under the Fair Debt Collection Practices Act, the agency must prove the debt is valid before they can collect. Request this in writing by sending a certified letter to the address on the notice. The agency then has 30 days to send you proof that the debt is yours.
If the agency cannot verify the debt, they must stop collection efforts. If they can verify it, you can negotiate a settlement (paying less than the full amount) or a payment plan. Do not send money until you have a written agreement about what you're paying and what the agency will do in return (such as remove the account from your credit report or stop calling).
Frequently Asked Questions
Can I set up automatic payments through Quest Bill Pay?
Quest's online portal allows you to save your payment method for future use, but you must manually authorize each payment. There is no automatic recurring payment option through Quest Bill Pay itself. If you want automatic payments, you would need to set that up through your bank's bill pay service instead.
What payment methods does Quest Bill Pay accept?
Quest accepts debit cards, credit cards, and bank account transfers (ACH). They do not accept checks through the online portal, but you can mail a check to the address on your bill. Credit card payments may incur a processing fee depending on the card issuer, not Quest.
If I pay my Quest bill by credit card, will that hurt my credit score?
Paying a medical bill with a credit card does not hurt your score directly. However, if you carry a balance on that credit card, the higher balance will increase your credit utilization ratio, which can lower your score slightly. Paying off the credit card balance immediately after paying Quest avoids this.
How long does it take for a Quest payment to show up in my account?
Online payments typically post within one business day. Payments made by phone may take one to two business days. Mailed checks can take five to seven business days depending on mail delivery and Quest's processing time. If you need the payment to post quickly, online or phone payment is faster.
Can I dispute a Quest bill after I've already paid part of it?
Yes. Paying part of a bill does not waive your right to dispute the charges. Contact Quest's billing department or patient advocate and explain what you believe is incorrect. Keep records of all payments you've made and copies of any correspondence about the dispute.
