How insurance covers PET scans for pets

Most pet insurance policies cover PET scans (positron emission tomography scans) the same way they cover other diagnostic imaging — as part of your plan's coverage for diagnostic tests. The scan itself is usually covered at your plan's standard reimbursement rate, which typically ranges from 70 to 90 percent of the veterinary bill after you meet your deductible. However, coverage depends entirely on your specific policy, your deductible, any annual limits, and whether your veterinarian is in-network or out-of-network.

PET scans are expensive — usually between $2,000 and $4,000 per scan — so understanding what your policy actually covers before your pet needs one can save you thousands of dollars. The key is knowing whether your plan covers diagnostic imaging at all, what percentage it reimburses, and whether there are caps on how much the insurance will pay toward imaging in a given year.

Key Takeaways

  • PET scans are covered under the diagnostic imaging section of most pet insurance policies, reimbursed at your plan's standard percentage (usually 70 to 90 percent) after your deductible.
  • Your policy documents list what diagnostic tests are covered and any annual or per-incident limits on imaging costs, so you need to read your actual plan before scheduling.
  • In-network veterinary hospitals may offer better reimbursement rates or direct billing, so asking your vet whether they work with your insurer can lower your out-of-pocket cost.
  • Pre-authorization from your insurance company before the scan is performed can prevent claim denials and confirm exactly what portion will be reimbursed.
  • If your current policy does not cover PET scans or has low limits, you can only add coverage by switching plans during your policy's renewal period.

Check your policy documents for imaging coverage limits

Your pet insurance policy includes a section on what diagnostic tests are covered. Open your policy documents or log into your insurer's online portal and search for "diagnostic imaging," "diagnostic tests," or "radiology." This section will tell you whether PET scans are covered at all, what percentage of the cost is reimbursed, and whether there is an annual cap on imaging expenses.

Some policies cap diagnostic imaging at a set dollar amount per year — for example, $500 or $1,000 — which means once you hit that limit, no further imaging is covered that year. Others have no imaging cap but explore your overall annual limit to all claims, including imaging. A few policies exclude certain types of imaging entirely or cover only X-rays and ultrasounds, not advanced scans like PET. If your policy is unclear, call your insurer's customer service line and ask specifically: "Are PET scans covered under my plan, and if so, what is the reimbursement percentage and any annual limit on imaging?"

Understand your deductible and reimbursement percentage

Before your insurance pays anything toward a PET scan, you must meet your annual deductible — the amount you pay out of pocket each year before coverage begins. Deductibles typically range from $250 to $1,000 per year. Once you meet the deductible, your insurer reimburses a percentage of the remaining bill, usually 70, 80, or 90 percent depending on your plan level.

Here is how the math works: if your PET scan costs $3,000, your deductible is $500, and your reimbursement rate is 80 percent, you pay $500 upfront, then the insurer pays 80 percent of the remaining $2,500 (which is $2,000), and you pay the other 20 percent ($500). Your total out-of-pocket cost is $1,000. If you have already met your deductible earlier in the year for another claim, the insurance would pay 80 percent of the full $3,000 ($2,400), and you would pay $600. Check your policy to see whether your deductible resets each calendar year or on your policy's anniversary date.

Request pre-authorization before the scan

Before your veterinarian schedules a PET scan, contact your insurance company and ask for pre-authorization. This means the insurer reviews the claim in advance and confirms in writing that the scan is covered under your plan and what percentage will be reimbursed. Pre-authorization does not may provide payment — your pet still has to meet the policy's terms — but it prevents surprises and protects you if there is a dispute later about whether the scan was medically necessary.

To request pre-authorization, call your insurer's claims department and provide your pet's policy number, your veterinarian's name and clinic, the reason for the scan, and the estimated cost. Ask the representative to send you a written confirmation of what will be covered. Some insurers allow you to submit pre-authorization requests online through their portal. If your vet's office handles claims paperwork, ask them to request pre-authorization on your behalf — many veterinary clinics do this routinely and can speed up the process.

Know the difference between in-network and out-of-network vets

Some pet insurance companies have networks of preferred veterinary hospitals that offer direct billing or higher reimbursement rates. If your vet is in-network, the clinic may bill your insurance directly, and you pay only your deductible and coinsurance (your percentage of the cost) at the time of service. If your vet is out-of-network, you typically pay the full bill upfront and submit a claim to your insurer for reimbursement, which takes longer.

Before scheduling a PET scan, ask your veterinarian whether they are in-network with your insurance company. If they are not, ask whether they can submit claims electronically or if you will need to handle the paperwork yourself. Some out-of-network vets will still file claims on your behalf as a courtesy. Knowing this in advance helps you plan for cash flow and understand how long reimbursement will take — in-network claims often process within days, while out-of-network reimbursement can take two to four weeks.

Submit your claim with the right documentation

After your pet's PET scan, your veterinarian will provide an itemized invoice showing the scan cost and the reason it was performed. If your vet did not submit the claim automatically, you will need to file it yourself. Log into your insurance company's online portal or call their claims department and provide your pet's policy number, the invoice, and any supporting documents your vet included (such as notes explaining why the scan was medically necessary).

Keep copies of everything — the original invoice, your claim submission confirmation, and any pre-authorization letter. If your claim is denied or reimbursed at a lower rate than expected, you will have documentation to dispute it. Most insurers process claims within 10 to 30 days, though some take longer. You can check the status of your claim online or by calling customer service.

Consider switching plans if your current coverage is inadequate

If your current policy does not cover PET scans, has a very low reimbursement percentage, or caps imaging at an amount that would not cover a full scan, you cannot add coverage mid-year. Pet insurance policies are locked in once they start, and you cannot change coverage levels or add benefits until your renewal date. However, when your policy renews, you have the option to switch to a different plan with better imaging coverage.

Before your renewal date, compare plans from your current insurer and others, paying special attention to diagnostic imaging coverage. Some insurers offer plans specifically designed for pets with chronic conditions that require frequent imaging. If your pet has already been diagnosed with a condition that will need PET scans, note that most insurers exclude pre-existing conditions, so switching plans will not help unless your pet develops a new condition after the policy starts.

Frequently Asked Questions

Will my insurance cover a PET scan if my vet says it is medically necessary?

Medical necessity alone does not may provide coverage. Your insurance covers the scan only if your policy includes diagnostic imaging and the scan is not excluded for other reasons — such as being related to a pre-existing condition or exceeding your annual imaging limit. Pre-authorization confirms whether your specific scan will be covered before you pay for it.

What happens if I do not get pre-authorization before the scan?

Your claim may still be approved if the scan meets your policy's terms, but without pre-authorization, there is a higher risk of denial or a lower reimbursement if your insurer later decides the scan was not covered. Pre-authorization protects you by getting written confirmation in advance.

Can I get reimbursed if I already paid for a PET scan out of pocket?

Yes, if the scan is covered under your policy. Submit your itemized invoice and any supporting documents to your insurer within the time limit stated in your policy (usually 30 to 90 days). The insurer will reimburse you at your plan's reimbursement rate, minus your deductible if you have not met it yet.

Does pet insurance cover PET scans for cancer screening if my pet has no symptoms?

Most policies cover diagnostic imaging only when a veterinarian orders it to diagnose or monitor an existing condition. Preventive or screening scans in pets with no symptoms are usually not covered. Check your specific policy or ask your insurer whether screening scans are an exception.

What if my insurance denies my PET scan claim?

Request a written explanation of the denial from your insurer. Common reasons include the scan being related to a pre-existing condition, exceeding your annual limit, or the insurer determining it was not medically necessary. You can appeal the decision by submitting additional documentation from your veterinarian explaining why the scan was needed.
