Quest Diagnostics accepts Medicaid, but coverage depends on your specific plan and state

Quest Diagnostics is one of the largest lab testing networks in the United States and does work with Medicaid. However, whether your Medicaid plan covers a test at Quest, and what you pay out of pocket, depends on three things: which state's Medicaid program you're in, which Medicaid plan you have (managed care or fee-for-service), and whether your doctor orders the test as medically necessary.

Not every Medicaid plan covers every test. Some states' Medicaid programs have contracts with Quest; others don't. Some managed care plans within a state contract with Quest; others direct members to different labs. The only way to know for certain is to call the customer service number on the back of your Medicaid card before you go in for testing.

Key Takeaways

  • Quest Medicaid acceptance varies by state and by which specific Medicaid plan you have, so you must check your own plan before scheduling.
  • Call the number on your Medicaid card to confirm whether your plan covers the specific test your doctor ordered at Quest.
  • If your plan doesn't cover Quest, ask your doctor whether they can order the test through a lab your plan does cover.
  • Bring your Medicaid card and a photo ID to Quest; you typically pay nothing if the test is covered and medically necessary.

How to check if your Medicaid plan covers Quest

Start by calling the customer service number on the back of your Medicaid card. Tell them you need a lab test and ask whether Quest Diagnostics is in your plan's network. If it is, ask whether the specific test your doctor ordered is covered. Some plans cover routine bloodwork but not specialized tests.

If you're on a managed care plan (HMO or PPO), the plan's network matters more than whether Quest is a national company. Your plan may have a contract with a different lab network in your state. If Quest isn't covered, ask which labs are, and whether your doctor can send the order there instead.

If you're on fee-for-service Medicaid (the state runs it directly rather than a private plan), Quest is more likely to be accepted, but you still need to confirm. Some states have preferred lab networks even for fee-for-service.

What to bring to Quest if your plan covers it

Bring your Medicaid card and a photo ID. Quest will scan your card to verify coverage before the test. If your plan covers the test and your doctor ordered it as medically necessary, you should pay nothing at the time of service.

If Quest cannot verify your coverage on the spot, ask them to contact your Medicaid plan directly. Do not leave without knowing whether you're covered, because if there's a problem, you could receive a bill later. If there is a discrepancy, ask Quest to document it in writing before you proceed.

What happens if your Medicaid plan doesn't cover Quest

If your plan doesn't contract with Quest, you have two options. First, ask your doctor whether they can order the test through a lab your plan does cover. Most doctors work with multiple labs and can reroute the order.

Second, you can still go to Quest and pay out of pocket, but this is usually expensive. Quest does offer cash-pay pricing that is lower than the standard bill, but it is still higher than what Medicaid would pay. Ask Quest for their cash price before you decide.

If you receive a bill from Quest after your test

If you get a bill from Quest after your visit, even though you showed your Medicaid card, contact your Medicaid plan first. Tell them the date of service, the test name, and Quest's reference number. Ask the plan to review whether the test should have been covered.

If your plan says it should have covered the test, the plan will contact Quest directly to resolve the bill. If your plan says the test wasn't covered, ask why. Sometimes a test is not covered because it wasn't ordered as medically necessary, or because your plan requires pre-approval for certain tests.

If you disagree with your plan's decision, you can file a complaint with your state's Medicaid office. The process is called an appeal, and your state Medicaid program has a formal procedure for it.

Medicaid coverage for specific types of tests at Quest

Medicaid typically covers routine tests that a doctor orders for diagnosis or monitoring of a health condition. This includes bloodwork for cholesterol, diabetes screening, thyroid function, and basic metabolic panels. It also covers drug screening tests when ordered by a doctor.

Medicaid is less likely to cover tests ordered for personal reasons rather than medical ones — for example, a paternity test or a test for a job physical if the job isn't Medicaid-related. Some states cover these; others don't. Ask your plan before you schedule.

Specialized tests, genetic testing, and tests for wellness or prevention (not tied to a current health problem) may require pre-approval from your Medicaid plan before Quest performs them. Your doctor's office usually handles this request, but confirm that they've done it before you go in.

Frequently Asked Questions

Do I need a referral to go to Quest with Medicaid?

No. You need a doctor's order for the test itself, but not a referral to Quest as a facility. Your doctor writes an order for the lab work, and you can take it to any Quest location. However, if your Medicaid plan is an HMO, check first whether Quest is in your network, because using an out-of-network lab may result in a bill.

What if I don't have my Medicaid card with me?

Call your Medicaid plan's customer service number (you can find it online using your name and date of birth) and ask them to provide your member ID number. Give this to Quest. They can verify your coverage with the number alone, though having the physical card is faster.

Can Quest bill me if my Medicaid plan denies the test?

Yes, if your plan determines the test wasn't medically necessary or wasn't covered under your plan, Quest can bill you. However, Quest must give you notice before the test that it may not be covered. If you receive a bill, you can dispute it through your plan's appeal process.

Does Quest offer payment plans if I get a bill?

Quest does offer payment plans for bills, but this is separate from Medicaid coverage. If you receive an unexpected bill, contact Quest's billing department to ask about options. However, first confirm with your Medicaid plan that the test truly wasn't covered, because the plan may pay it retroactively.
