What a PET Scan Costs When You Have Insurance

A PET scan with insurance typically costs you between $0 and $500 out of pocket, depending on your plan's deductible, coinsurance percentage, and whether the imaging center is in your network. Most people with standard health insurance pay a copay of $50 to $250 if their doctor orders the scan for a covered reason—usually cancer screening, dementia evaluation, or cardiac assessment. The insurance company covers the rest, which is substantial: a PET scan billed to insurance runs $3,000 to $6,000 before any negotiated discount.

Your actual cost depends on three things: whether you've met your deductible for the year, what percentage of the cost your plan requires you to pay after the deductible (coinsurance), and whether the imaging facility has a contract with your insurer. If you haven't met your deductible, you may pay the full negotiated rate until you do. Once you've met it, coinsurance typically ranges from 10 to 20 percent of the remaining bill.

Key Takeaways

  • Your out-of-pocket cost depends on your deductible status, coinsurance percentage, and whether the imaging center is in-network with your insurance plan.
  • In-network PET scans usually cost $50 to $250 out of pocket; out-of-network scans can cost significantly more because you lose the negotiated rate discount.
  • Call your insurance company before scheduling to confirm the scan is covered for your specific medical reason and to learn your exact cost responsibility.
  • If cost is a barrier, ask your doctor whether a less expensive imaging option (CT, MRI, or ultrasound) might answer the same medical question.

How to Find Your Exact Out-of-Pocket Cost

Contact your insurance company directly before you schedule the scan. Have your member ID ready and tell them the specific reason your doctor wants the PET scan—for example, "staging for lung cancer" or "evaluating cognitive decline." Insurance covers PET scans only for certain diagnoses, and your plan may not cover all of them. The representative can tell you whether your reason is covered and what you'll owe.

Ask three specific questions: (1) Have I met my deductible this year? (2) What is my coinsurance percentage for imaging? (3) Is [the imaging center name] in-network? If the center isn't in-network, ask whether your plan covers out-of-network imaging and at what percentage. Out-of-network scans often cost you 30 to 50 percent of the billed amount instead of 10 to 20 percent.

Write down the name of the representative and the date you called. If your bill later doesn't match what they told you, you have documentation to dispute it.

In-Network Versus Out-of-Network Imaging Centers

An in-network imaging center has a contract with your insurance company that locks in a negotiated rate—typically $3,000 to $4,500 for a PET scan. Your coinsurance is calculated on that lower number. An out-of-network center can bill the full "usual and customary" rate, which may be $5,000 to $6,000 or higher. Even if your plan covers out-of-network imaging, you pay coinsurance on that higher amount, which can double your bill.

Always ask your doctor which imaging centers they use and whether those centers are in-network with your insurance. If your doctor's preferred center is out-of-network, ask whether another in-network center can perform the same scan. Most insurance websites have a "find a provider" tool where you can search for in-network imaging facilities in your area.

What Happens If You Haven't Met Your Deductible

If you haven't met your annual deductible, you pay the full negotiated in-network rate until you reach it. For example, if your deductible is $1,500 and you've paid $800 so far this year, a $3,500 PET scan means you pay $700 (the remaining deductible) plus 20 percent coinsurance on the remaining $2,800, which is $560—a total of $1,260 out of pocket.

This is why timing matters. If you're early in the calendar year and haven't met your deductible, a PET scan will cost you more than if you had the same scan in December after meeting it. Some people schedule elective imaging later in the year for this reason, though your doctor's medical judgment about when you need the scan should come first.

Medical Reasons Insurance Typically Covers PET Scans

Insurance covers PET scans when they help diagnose or stage cancer, evaluate dementia or Alzheimer's disease, assess cardiac viability after a heart attack, or investigate certain seizure disorders. Coverage varies by plan and insurer. Some plans cover PET scans for all cancers; others limit coverage to specific types like lung, breast, or lymphoma. A few plans require you to try a less expensive imaging method first (like a CT scan) before approving a PET scan.

Your doctor's office usually handles getting prior authorization from your insurance company before the scan is scheduled. If authorization is denied, ask your doctor to appeal or to explain in writing why a PET scan is medically necessary for your case. Some denials are reversed on appeal.

If Cost Is a Barrier

Talk to your doctor about whether a different imaging test might answer the same question at lower cost. A CT scan, MRI, or ultrasound may provide the information your doctor needs and typically cost less out of pocket. Your doctor can also contact the imaging center's financial counselor to ask about payment plans or reduced rates for uninsured or underinsured patients—some centers offer these even when insurance is involved.

If you're uninsured or your insurance doesn't cover the scan, ask the imaging center for their cash price. Many centers offer discounts of 20 to 40 percent if you pay upfront without insurance. Get the quote in writing before you schedule.

Common Mistakes to Avoid

Don't assume your scan is covered just because your doctor ordered it. Coverage depends on your specific diagnosis and your specific plan. Verify coverage before the appointment, not after the bill arrives.

Don't schedule at the first imaging center your doctor mentions without checking whether it's in-network. A five-minute phone call to confirm in-network status can save you hundreds of dollars.

Don't ignore a bill that's higher than the estimate your insurance company gave you. Call the imaging center's billing department and your insurance company to find the error. Billing mistakes are common, and many are corrected when you dispute them.

Frequently Asked Questions

Does insurance cover PET scans for screening if I don't have symptoms?

Most plans do not cover preventive PET scans. Insurance typically covers them only when you have symptoms or a diagnosis that makes the scan medically necessary. Ask your doctor whether your situation qualifies as diagnostic rather than preventive.

What if my insurance denies the PET scan?

Ask your doctor's office to request a peer-to-peer review, where your doctor speaks directly with the insurance company's medical reviewer. If that's denied, your doctor can file a formal appeal with written justification. You also have the right to appeal the denial yourself by contacting your insurance company's member services line.

Can I use my Health Savings Account or Flexible Spending Account to pay for a PET scan?

Yes. Both HSAs and FSAs cover imaging costs, including your copay, coinsurance, and deductible. You can use the account funds to pay the imaging center directly or to reimburse yourself after paying out of pocket.

Will I owe more if the PET scan finds something unexpected?

No. Your cost is based on the scan itself, not on what it shows. Whether the scan is normal or abnormal, your copay or coinsurance remains the same.

What's the difference between a PET scan and a PET-CT scan, and does insurance cover both?

A PET-CT combines a PET scan with a CT scan in one appointment. Insurance typically covers it the same way as a standalone PET scan if your doctor orders it for a covered reason. The combined scan may cost slightly more than a PET scan alone, but the difference is usually small.
