## Quick answer

Medicare pays providers about $544 on average for a cardiac PET scan. The full billed charge averages $1,666, and commercial insurers often pay $2,000 to $5,000 once facility fees, contrast agents, and stress-test components are included.

## What it is

A cardiac PET scan is a nuclear imaging test that shows how well blood flows to your heart muscle. A small amount of a radioactive tracer is injected into a vein. The tracer travels through your blood and is picked up by healthy heart muscle. A ring-shaped scanner then detects the tracer and builds a 3D picture of blood flow, both at rest and after your heart is stressed with exercise or medication.

Doctors use cardiac PET to look for coronary artery disease, old heart attacks, or areas of muscle that would benefit from a stent or bypass. It is considered one of the most accurate non-invasive tests for checking heart blood flow. It tends to give clearer images than a standard nuclear stress test (SPECT), and it uses less radiation.

Here's what's involved:

- **Time in the center:** about 2 to 3 hours total, including prep, tracer uptake, and scanning
- **Scan time on the table:** typically 20 to 45 minutes
- **Stress agent:** most cardiac PET scans use a medication like regadenoson or dipyridamole instead of a treadmill, since the tracer works best with pharmacologic stress
- **Anesthesia:** none; you stay awake the whole time
- **IV:** one for the tracer, sometimes a second for the stress drug
- **Recovery:** you can usually drive yourself home the same day

There are two Medicare billing codes for cardiac PET. The first covers the full PET and CT combined study, which is what most patients get. The second is a newer add-on code that measures absolute blood flow in milliliters per minute. Which ones your center bills depends on the equipment and protocol they use, not a clinical choice you make.

## When it is done

Cardiac PET is usually ordered when a simpler test like a treadmill stress test or SPECT scan is inconclusive, or when your body type or medical history would make those tests unreliable. It's particularly useful for patients who are overweight, have large breasts, or have existing conditions that create shadows on standard nuclear images.

Your doctor may recommend this when:

1. You have chest pain that might be coronary artery disease, and a standard stress test was inconclusive or unclear
2. A previous SPECT scan showed possible blockages that need confirmation before a catheterization
3. You've had a prior heart attack and your doctor wants to see how much heart muscle is still alive and worth revascularizing
4. You have known coronary disease and your cardiologist needs to judge whether a stent or bypass would actually help
5. You're being evaluated for cardiac sarcoidosis or another inflammatory heart condition (this uses a different tracer)
6. You can't exercise on a treadmill, but pharmacologic stress is safe for you

Alternatives include coronary CT angiography, cardiac MRI, standard SPECT nuclear stress testing, and invasive cardiac catheterization. Each has different strengths. Cardiac PET is typically the most sensitive non-invasive option for blood flow, but it's also among the most expensive and not every hospital has the equipment.

## What you pay

What you actually pay for cardiac PET depends more on your insurance type and where you have the scan than on anything clinical. Medicare pays physicians an average of $544 per study across the two main cardiac PET codes, but that's the physician reimbursement only. The total cost, including the facility's technical fee for the scanner, tracer, and stress agent, is several times higher. Commercial insurers typically pay total bills of $2,500 to $6,500, which is roughly 3x to 5x what Medicare pays once all components are added together.

**If you're on Medicare:**

- Cardiac PET is covered under Part B when your doctor documents medical necessity, usually after a prior cardiac workup
- You pay the annual Part B deductible ($257 in 2025 figure) if you haven't met it, then 20% coinsurance on the Medicare-allowed amount
- If you have a Medigap (supplemental) policy, it usually covers that 20%, leaving you with little to no bill
- Medicare Advantage plans may require prior authorization and have their own copays, often $50 to $250 for advanced imaging

**If you have commercial insurance:**

- Expect prior authorization; your cardiologist's office handles this, but denials are common for first-time requests
- You pay your deductible first, which can be $1,000 to $5,000+ for advanced imaging on high-deductible plans
- After the deductible, coinsurance runs 10% to 30% until you hit your out-of-pocket maximum
- Typical patient responsibility lands between $200 and $1,500, depending on where you are in your plan year

**If you're uninsured or paying cash:**

- Freestanding imaging centers sometimes advertise bundled cash-pay rates of $1,500 to $3,500, substantially lower than hospital list prices
- Hospital list prices can exceed $8,000, but almost no one pays those; ask for the cash-pay or financial-assistance rate
- Nonprofit hospitals must offer financial assistance under IRS rules; ask the billing office for their charity-care policy in writing
- Call three places and ask for an all-in bundled price in writing before you schedule

## Anatomy of the bill

A cardiac PET scan usually generates multiple bills, even though you only show up to one place. Understanding the pieces helps you spot errors and anticipate what's coming.

**Facility fee (technical component):** Charged by the hospital or imaging center for the scanner time, tracer handling, nursing staff, and room. This is the biggest single line. Hospital outpatient facilities typically charge $1,500 to $5,000; freestanding imaging centers often come in at $800 to $2,500 for the same service.

**Professional interpretation fee:** The physician who reads your scan, usually a cardiologist or radiologist, bills separately for interpretation. Medicare pays about $80 to $150 for this; commercial insurers pay more.

**Radiotracer cost:** Cardiac PET uses Rubidium-82 or N-13 ammonia. Rubidium is produced on-site in a generator; ammonia is made in a cyclotron. Tracer cost can run $200 to $800 per study and is sometimes billed as a separate line.

**Stress agent:** Regadenoson (brand name Lexiscan) or dipyridamole. Regadenoson alone can add $100 to $400 to the bill.

**Attenuation-correction CT:** Included in the main PET code (78431) and generally not billed separately, but some centers bill it anyway. Check your Explanation of Benefits.

**Stress supervision by a physician:** A separate professional fee may apply if a cardiologist physically supervised the stress portion.

Ask in advance whether the facility bills globally (one combined charge) or itemizes every line. Itemized bills have more room for error but also more room for pushback.

## Cost by state

State-level Medicare payments for cardiac PET range from a low of about $43 in North Dakota to a high of roughly $1,427 in Alabama. These differences mostly reflect which billing code the state's providers use more often, not what the scan truly costs. States where centers mostly bill the comprehensive 78431 code (PET with CT) show much higher averages than states where more 78434 add-on codes are billed.

Texas has the highest overall volume of cardiac PET scans in Medicare data (nearly 75,000 services), followed by Missouri, Pennsylvania, Illinois, and Kansas. Florida, California, and New York also perform tens of thousands of these scans annually.

Why costs vary by state:

- **Medicare geographic adjusters (GPCI):** Federal rates are adjusted for local wages, rent, and malpractice costs, so urban coastal states run 10% to 20% higher than rural ones
- **Commercial negotiation strength:** Hospitals in concentrated markets negotiate higher rates with insurers, which can double or triple prices in some metro areas
- **Billing mix:** The same scan can be coded differently; states with more comprehensive billing show higher averages
- **Cost of living and wages:** Technologist wages and facility overhead vary significantly between regions

State averages are useful for rough comparison, but your actual cost is driven by which facility you pick within your state, not the state itself.

## Office vs facility

Medicare data shows a dramatic difference between office and facility settings: office-based cardiac PET averages about $888 in physician payment while facility-based (hospital outpatient) averages just $49. This isn't a real cost difference; it's a billing structure difference. In an office setting, the physician's practice owns the scanner and bills the full global fee (technical plus professional). In a hospital setting, the hospital bills the technical component separately under OPPS, and the physician gets only the small professional reading fee. Your total out-of-pocket can still be higher at a hospital because the facility component is much larger.

The real choice for patients is hospital outpatient imaging versus a freestanding or office-based imaging center.

When a hospital setting makes more sense:

- You have complex cardiac disease and want the ICU, cath lab, and cardiology team in the same building
- Your insurance only contracts with the hospital network for advanced imaging
- You've had adverse reactions to stress agents and prefer on-site emergency backup

When a freestanding imaging center makes more sense:

- You're paying cash or have a high-deductible plan; freestanding rates often run 40% to 60% lower for the identical scan
- You want faster scheduling; hospitals often book out further
- Your cardiologist has privileges at or reads for the freestanding center
- Your situation is stable and you don't need cardiac emergency services on site

## Who performs the procedure

Most cardiac PET scans are performed under the supervision of cardiologists. Medicare data shows cardiovascular disease specialists account for about 538,000 services with more than 1,000 providers billing for cardiac PET, roughly 76% of total volume. Interventional cardiologists perform another ≈120,000 services. Diagnostic radiologists and nuclear medicine physicians handle the remainder, though a smaller share.

What to look for when choosing a specialist:

- **Volume:** Pick a center that performs cardiac PET regularly, not occasionally. Image quality and interpretation accuracy correlate strongly with volume.
- **Board certification:** Your reading physician should be board certified in cardiology, radiology, or nuclear medicine, ideally with subspecialty certification in nuclear cardiology (CBNC)
- **Accreditation:** Look for facilities accredited by the Intersocietal Accreditation Commission (IAC) or American College of Radiology (ACR) for nuclear cardiology
- **Equipment generation:** Modern PET/CT scanners deliver better image quality with lower radiation; ask whether the scanner is less than 10 years old
- **Ability to run absolute flow quantification:** Not every center does this; it adds diagnostic value for certain patients
- **Protocol match to your body:** Ask whether they use rubidium or ammonia; rubidium is more common and doesn't require an on-site cyclotron

Cardiac electrophysiologists and internal medicine physicians also appear in the data but at very low volumes. These are typically supervising or consulting roles rather than primary interpreters. When you schedule, confirm that the reading physician is a cardiologist or radiologist with nuclear cardiology training.

## How to shop for the best price

Cardiac PET is one of the most shoppable tests in cardiology because the same scan at two locations can differ by thousands of dollars. Use this playbook:

1. **Request a Good Faith Estimate in writing.** Under the 2022 No Surprises Act, uninsured and self-pay patients are entitled to a written estimate before scheduled imaging. Ask for one from every facility you're considering.
2. **Verify every billing party is in-network.** For cardiac PET that usually means: the facility, the interpreting physician (cardiologist or radiologist), and sometimes a supervising physician for the stress portion. Call each separately; don't rely on the scheduler.
3. **Compare hospital outpatient vs freestanding imaging centers.** Get written quotes from at least one of each. Freestanding centers routinely charge 40% to 60% less for the identical scan.
4. **Ask about bundled vs itemized billing.** A bundled quote covers the scan, tracer, stress agent, and interpretation under one price. Itemized billing opens the door to surprise line items like tracer or stress-agent fees.
5. **Ask about payment plans and charity care.** Nonprofit hospitals are required to publish financial assistance policies. Cash-pay discounts of 30% to 60% are common when you ask.
6. **Get a second opinion on whether PET is the right test.** Sometimes a standard SPECT, a coronary CT angiogram, or cardiac MRI answers the same question for less money. A cardiologist (not the one ordering the scan) can weigh in.
7. **Confirm prior authorization before the scan.** If your insurer requires it and the facility didn't obtain it, you can be held responsible for the full bill.

Red flags to watch for: a facility that won't give you a written estimate, an interpretation fee billed by a physician you've never heard of, or an itemized bill that adds tracer or stress-agent charges on top of what was supposed to be a bundled price. Vague verbal quotes like 'it'll depend on your insurance' are not estimates. Push for numbers in writing.

## Surprise billing risks

Cardiac PET is an area where surprise bills happen often, because multiple providers touch the study and patients usually only meet one of them. You show up to a hospital that's in your network, the scan happens, and weeks later a separate bill arrives from a physician group you've never heard of.

Most common surprise-billing sources for cardiac PET:

- **Out-of-network interpreting physician:** The cardiologist or radiologist who reads your scan may contract separately and be out-of-network even when the hospital is in-network
- **Stress supervising physician:** A separate cardiologist sometimes supervises the pharmacologic stress portion and bills independently
- **Tracer and stress-agent charges:** Occasionally billed as a separate drug claim that wasn't included in the facility estimate
- **Prior authorization gaps:** If authorization was not secured in advance, the insurer may deny the entire claim, leaving you with full billed charges
- **Hospital facility fee for outpatient imaging:** Some patients assume an imaging center is a freestanding site, but it is actually a hospital outpatient department with higher fees

If you get a surprise bill:

- Don't pay until you've verified the charge. Request a fully itemized bill and your insurer's Explanation of Benefits.
- The federal No Surprises Act (effective 2022) protects you from out-of-network balance billing at in-network facilities in many situations. File a dispute at cms.gov/nosurprises if you believe the law applies.
- Ask your insurer to reprocess the claim if any provider was out-of-network at an in-network facility.
- Escalate to your state insurance commissioner if the insurer refuses to resolve a clear No Surprises Act violation.

## Total recovery cost

Recovery from cardiac PET is straightforward because it's a non-invasive imaging test. You'll stay at the imaging center for about 2 to 3 hours for prep, the scan, and a short observation after the stress agent wears off. Most patients drive themselves home and return to normal activity the same day. You may be asked to avoid caffeine for 24 hours before the test, which is the main practical restriction. There are no incisions, no stitches, and no downtime from the procedure itself.

That said, the scan is rarely the last step in the workup. Most patients pay for a cascade of follow-on care, not just the PET. Budget for:

- **Cardiologist follow-up visit to review results:** $150 to $400 for a specialist office visit, less if you have insurance
- **Additional testing if PET is abnormal:** An invasive coronary angiogram can run $5,000 to $25,000; cardiac CT angiogram $500 to $3,000
- **New or adjusted medications:** Statins, beta-blockers, and antiplatelet drugs run $10 to $200 per month depending on brand and insurance
- **Preventive cardiology or lifestyle program:** $100 to $500 per visit, often not covered
- **Cardiac rehab (if you've had prior events):** 36 sessions typically, Medicare covers much of this
- **Stress-agent side-effect management:** Uncommon, but occasional short-term medication for headache or flushing
- **Time off work:** usually half a day for the scan itself; potentially more for follow-up appointments

The realistic episode-of-care cost for someone getting a cardiac PET and the workup it triggers is typically 2x to 5x the sticker price of the scan alone. Budget accordingly, especially if you're early in your deductible year.

## Frequently asked questions

### How much does a cardiac PET scan cost with insurance?

With commercial insurance, total billed charges typically run $2,500 to $6,500, but your out-of-pocket is usually $200 to $1,500 depending on your deductible and coinsurance. Medicare covers it under Part B with a 20% coinsurance after deductible, so Medigap holders often pay little to nothing. Always confirm prior authorization was obtained before the scan.

### Does Medicare cover cardiac PET?

Yes. Medicare Part B covers cardiac PET for coronary artery disease, myocardial viability assessment, and certain other cardiac indications when your physician documents medical necessity. You pay the Part B deductible ($257 in 2025 figure) and 20% coinsurance on the Medicare-allowed amount. Medicare Advantage plans usually require prior authorization and may have specific network restrictions.

### How long does a cardiac PET scan take?

Plan for 2 to 3 hours at the imaging center. Actual scanning on the table is typically 20 to 45 minutes. Most of the time is IV placement, tracer injection, waiting for the tracer to circulate, and the pharmacologic stress portion. You can usually drive yourself home the same day.

### What's the difference between the two cardiac PET codes I might see on my bill?

Code 78431 is the comprehensive cardiac PET with attenuation-correction CT, which most patients receive. Code 78434 is a newer add-on for absolute myocardial blood flow quantification, billed when the scanner and protocol support it. If both appear on your bill, that usually means the center performed absolute flow quantification in addition to the standard study.

### How do I avoid a surprise bill for cardiac PET?

Confirm that the facility, the interpreting physician, and any stress-supervising physician are all in your network, in writing. Request a Good Faith Estimate before the scan. Verify prior authorization is completed. After the scan, compare your Explanation of Benefits to every bill and dispute anything that doesn't match. Federal No Surprises Act protections apply in many out-of-network scenarios at in-network facilities.

### What's the cheapest way to get a cardiac PET scan?

Cash-pay or self-pay at a freestanding imaging center is usually the cheapest route, often 40% to 60% below hospital prices. Ask for a bundled quote in writing. Nonprofit hospitals must offer financial assistance; ask for the charity-care application. If you're uninsured, don't accept the list price; negotiate for the Medicare-equivalent or cash-pay rate.

### Is cardiac PET better than a regular nuclear stress test?

For most blood-flow questions, yes. Cardiac PET has higher sensitivity and specificity than SPECT, uses less radiation, and gives better images in larger patients or those with prior inconclusive SPECT results. It's also more expensive and not available at every hospital. Your cardiologist weighs cost, access, and diagnostic need before ordering it.

### Where does this cost data come from?

The Medicare figures on this page come from the CMS Medicare Part B Physician and Other Practitioners public use data (most recent full calendar year), covering provider-level payments for HCPCS codes 78431 and 78434. Commercial, cash-pay, and out-of-pocket ranges are estimates based on publicly reported data and typical commercial-to-Medicare rate ratios; your actual price depends on your plan, state, and facility.
