Quest Does Accept Medicaid, But Coverage Depends on Your Plan and State
Quest Diagnostics accepts Medicaid, but whether your specific Medicaid plan covers the lab work depends on which state you live in, which Medicaid program you're enrolled in, and what type of test your doctor ordered. Quest is one of the largest lab networks in the country, so most Medicaid plans do work with them — but you'll need to confirm before your appointment to avoid an unexpected bill.
The confusion happens because Medicaid is run by each state, not federally. Your state's Medicaid program decides which labs it contracts with and what tests it covers. Even if Quest accepts Medicaid in your state, your particular plan might not cover the specific test you need, or you might need a referral first.
Key Takeaways
- Quest Diagnostics accepts Medicaid in most states, but you must verify your specific plan covers the test before you go.
- Call Quest's customer service or your Medicaid plan directly to confirm coverage — this takes five minutes and prevents a bill later.
- Some Medicaid plans require a referral from your doctor before Quest can bill them, even if they accept Medicaid generally.
- If your plan doesn't cover the test at Quest, ask your doctor whether another lab network your Medicaid covers can do it instead.
How to Confirm Quest Accepts Your Medicaid Plan
Before you schedule or go to Quest, contact your Medicaid plan directly. You can find the phone number on your Medicaid card or on your state's Medicaid website. Tell them you need lab work at Quest and ask whether your plan covers it. They'll tell you yes or no in one call, and they can also tell you whether you need a referral from your doctor first.
You can also call Quest's customer service line at 1-800-222-0446 and ask whether they accept your specific Medicaid plan. Have your Medicaid card handy when you call. Quest can tell you whether they're in-network for your plan, though they may not be able to tell you whether your particular test is covered — that's a question for your Medicaid plan itself.
If you're calling your Medicaid plan, ask three things: Does Quest accept my plan? Does my plan cover this specific test? Do I need a referral? Writing these down before you call makes the conversation faster.
What Happens If Your Plan Doesn't Cover Quest
If your Medicaid plan doesn't contract with Quest, ask your doctor to order the lab work through a lab your plan does cover. Most states' Medicaid programs contract with at least one major lab network — LabCorp, Quest, or Sonic Healthcare are common — so there's usually an alternative nearby.
If you go to Quest anyway without confirming coverage, you may receive a bill. Quest will bill your Medicaid plan first, but if your plan doesn't cover it, Quest can bill you for the full cost of the test. This is why the five-minute phone call before your appointment matters.
Referrals and Prior Authorization
Some Medicaid plans require your doctor to send a referral or get prior authorization before Quest can bill them. This doesn't mean the test isn't covered — it means your plan wants your doctor to confirm the test is medically necessary first. Your doctor's office usually handles this, but it can add a few days to the process.
When you call your Medicaid plan to confirm coverage, ask whether prior authorization is needed. If it is, tell your doctor's office before your appointment so they can submit the request in time. If your doctor orders the test without getting authorization first, Quest may not be able to bill your plan, and you could end up with a bill.
What Tests Quest Offers Under Medicaid
Quest offers a wide range of lab tests — blood work, urinalysis, drug screening, and many others. Most routine tests that your doctor orders are covered by Medicaid plans that contract with Quest. However, some specialized or elective tests may not be covered, even if Quest performs them.
Your Medicaid plan decides which tests it covers, not Quest. If your doctor orders a test that your plan doesn't cover, your plan will deny it, and you may be billed. This is another reason to confirm coverage before your appointment — your Medicaid plan can tell you whether the specific test your doctor ordered is covered.
Finding a Quest Location Near You
Quest has thousands of patient service centers across the country. You can find one near you on Quest's website by entering your zip code. When you call to confirm your Medicaid plan is accepted, ask whether the specific location you plan to visit accepts your plan — coverage can sometimes vary by location, though this is rare.
Most Quest locations are open early morning through evening on weekdays, and many are open on Saturday. You don't usually need an appointment for routine lab work, but calling ahead to confirm the location is open and has the supplies for your specific test can save a trip.
What to Bring to Your Quest Appointment
Bring your Medicaid card, a photo ID, and any paperwork your doctor gave you with the lab order. If your doctor sent the order electronically to Quest, you may not need the paper copy, but having it doesn't hurt. Quest can look up electronic orders by your name and date of birth.
If your Medicaid plan requires a referral, bring that too, or make sure your doctor's office sent it to Quest before you arrive. If the referral wasn't received, Quest will tell you, and you may need to reschedule or contact your doctor's office to resend it.
Frequently Asked Questions
Will I have to pay anything at Quest if my Medicaid plan covers the test?
No, you should not pay anything at the time of service if your Medicaid plan covers the test and you've confirmed coverage beforehand. Quest will bill your Medicaid plan directly. If you're asked to pay a copay, ask Quest whether your specific Medicaid plan requires one — some do, some don't.
What if I go to Quest without confirming coverage first and get a bill?
Contact Quest's billing department and explain that you have Medicaid. Ask them to resubmit the claim to your plan if they haven't already. If your plan denies it, ask Quest whether you can dispute the bill or set up a payment plan. You can also contact your Medicaid plan to ask why they denied it.
Can I use Quest if I have Medicaid managed care instead of regular Medicaid?
Yes, but managed care plans have their own networks. Call your managed care plan's customer service number (on your card) to confirm Quest is in-network. Managed care plans sometimes contract with different labs than regular Medicaid, so you must check your specific plan.
Do I need a referral from my doctor to go to Quest with Medicaid?
It depends on your plan and the type of test. Some Medicaid plans let you go directly to Quest with a lab order from your doctor; others require a referral first. Call your Medicaid plan to ask. Your doctor's office can also tell you whether they need to send a referral.
What if my state's Medicaid doesn't contract with Quest?
A few states have limited contracts with Quest, but most do. If your state doesn't, your Medicaid plan will tell you which labs it does contract with when you call. Ask your doctor to order the test through one of those labs instead.
