Answer #1: In most outpatient centers a PET scan runs about $920 and Medicare picks up 80% that means youre looking at roughly $180 out of pocket.
Answer #2: In a hospital outpatient department the same study can be billed at $1,599, so your 20% coinsurance climbs to about $320. No insurance? Expect to pay anywhere from $1,300 to $4,600 for a fullbody scan.
Medicare Basics
Why Medicare Covers PET Scans
Medicare isnt just a onesizefitsall program it specifically covers PET scans when theyre medically necessary for things like cancer staging, heartdisease assessment, or Alzheimers diagnosis. The policy is built around the idea that early, accurate imaging can save lives and, ultimately, costs down the road.
What Medicare PartB Pays
PartB typically reimburses 80% of the approved amount that the government sets for each CPT code (for example, 78815 for a wholebody FDGPET). The remaining 20% is your responsibility unless you have supplemental coverage.
When PartA May Apply
If you end up hospitalized and the PET scan is part of an inpatient stay, PartA steps in after youve met the 2025 deductible of $1,676. Most people, however, get the scan in an outpatient setting, so PartB is the workhorse.

FullBody vs Targeted
Cost of a FullBody PET Scan
A fullbody PET scan, which covers from the skull base down to midthigh, is the biggest ticket on the list. Without insurance youll see bills ranging anywhere from $1,300 to $4,600, depending on location and the specific radiotracer used. With Medicares 80% coverage, most patients end up paying between $161 and $284.
Factors That Influence Price
- Facility type: Ambulatory surgical centers usually charge less than large academic hospitals.
- Geography: Pricing varies widely by state; the Medicare Procedure Price Lookup tool is a lifesaver for spotting regional differences.
- Scan type: FDGPET is the standard; newer amyloid PET scans for Alzheimers can be pricier.
- Contrast usage: Adding contrast bumps the bill up a few hundred dollars.
PriceCheck Checklist
Before you schedule, run through this quick list:
- Ask the provider for the exact CPT code (usually 78815).
- Confirm the facility accepts Medicare directly; otherwise you might be billed the full amount and have to file for reimbursement.
- Request a written price estimate most offices will give you one within 48hours.
- Verify whether you need prior authorization for an amyloid PET or cancerspecific study.
Lifetime Coverage
No Lifetime Cap
Good news: Medicare doesnt set a hard limit on the number of PET scans you can receive over a lifetime. The only gatekeeper is medical necessity, which your doctor must document each time.
What Medical Necessity Means
In practice, it means your physician must write a clear note explaining why the scan is essential for instance, to stage newly diagnosed nonsmall cell lung cancer or to evaluate response after three cycles of chemotherapy. Some specialized scans, like amyloid PET for Alzheimers, may need prior authorization, but the process is straightforward if you have the paperwork ready.
Typical Frequency
| Condition | Typical Frequency | Medicare Comment |
|---|---|---|
| Cancer staging | Every 36months during treatment | Covered each time with proper documentation |
| Cardiac PET stress test | Annually or as clinically indicated | Covered if ordered for ischemia assessment |
| Alzheimers amyloid PET | Once, repeat only if clinically justified | Coverage expanding in 2025 |
Patient Story
Jane, a 68yearold lungcancer survivor, had three PET scans in one year to monitor tumor response. Each time her oncologist supplied a concise medical necessity note, and Medicare covered 80% of the costs leaving Jane with just a few hundred dollars in total outofpocket expenses.
Getting Covered Free
Steps to Maximize Coverage
If youre hoping to avoid any bill at all, there are a couple of avenues worth exploring:
- Confirm Medicare enrollment: Make sure PartB is active; otherwise you wont get the 80% reimbursement.
- Ask for a medical necessity letter: Your doctors written justification is the key to unlocking coverage.
- Check for supplemental plans: Medigap policies can pick up the remaining 20% and sometimes even eliminate it.
- Look for charity care or clinical trials: Some hospitals waive fees for patients who meet income criteria, and certain research studies provide scans at no charge.
Insurance Alternatives
If Medicare alone isnt enough, consider these options:
- Private PPO/HMO plans: Typically cover 8090% after you meet the deductible, which can lower your coinsurance.
- Medicare Advantage (MA) plans: Often have lower copays but require you to stay innetwork.
- Medigap (Supplemental) policies: Fill the 20% gap, frequently reducing your outofpocket to near zero.
Plan Comparison Table
| Plan Type | Deductible | Coinsurance / Copay | Typical OutofPocket for PET |

| Medicare PartB | $0 (after enrollment) | 20% | $180$320 |
| Private PPO | $1,500 | 1030% | $150$450 after deductible |
| Medicare Advantage | $0$500 | $0$50 copay | $0$100 (innetwork) |
