A DEXA scan, or dual-energy X-ray absorptiometry, is the standard tool for measuring bone mineral density. It takes 10 to 20 minutes, uses a fraction of the radiation of a chest X-ray, and produces a T-score that tells your doctor whether your bones are in the osteoporosis, osteopenia, or normal range. Doctors order it for women over 65, men over 65 with risk factors, anyone on long-term corticosteroids, and patients already diagnosed with osteoporosis who need to track whether treatment is working.
The price spread for this test is smaller than for most imaging, but site of service still matters. A DEXA scan at a hospital outpatient department costs 2 to 4 times more than the same scan at a freestanding imaging center or physician office. There is no clinical reason for this. The equipment, the technician skill required, and the resulting images are identical. The hospital simply bills at facility rates that include overhead unrelated to bone density testing. Patients who need other imaging such as a CT scan or X-ray can apply the same site-of-service cost-saving strategy.
This guide covers what a DEXA scan costs without insurance in 2026, what Medicare actually pays and who qualifies for $0 coverage, how to read your bill, and which billing errors show up most often on bone density claims. Medicare covers DEXA scans for qualifying patients who meet osteoporosis risk criteria. Medicare beneficiaries with Extra Help pay lower cost-sharing on related medications prescribed after a low bone density finding.
DEXA Scan Cost by Site of Service in 2026
The biggest cost driver of DEXA Scan is the site of service: where the procedure is performed. 2026 CMS price transparency data confirms a 2-3x billing differential between independent centers and hospital outpatient departments.
DEXA Scan prices without insurance vs. 2026 Medicare rates| Site of Service | Range Without Insurance | 2026 Medicare Rate |
|---|
| Physician office | $100 – $200 | ~$40 (PFS non-facility) |
| Independent imaging center | $100 – $250 | ~$40 (PFS non-facility) |
| Hospital outpatient department | $200 – $600 | ~$107 (OPPS APC 5522) |
| Mobile DXA unit or community screening | $65 – $150 | ~$40 (PFS non-facility) |

Why the Same Procedure Is So Much More at a Hospital
The 2026 Medicare Physician Fee Schedule pays approximately $39.61 for a DEXA scan (77080) performed at a non-facility setting such as a physician office or independent imaging center. The same scan at a hospital outpatient department is reimbursed at approximately $107 under the Hospital Outpatient Prospective Payment System (OPPS APC 5522). That 2.7x Medicare rate gap translates directly into higher cash prices at hospitals.
Because DEXA scanners are relatively low-cost to operate and require minimal technician time, independent imaging centers and physician offices can offer cash prices that closely track the Medicare rate. Hospital outpatient departments layer on facility fees that have nothing to do with the bone scan itself. If you have the choice of where to go, an independent center or your primary care physician's office will save you $100 to $400 out of pocket.
If a hospital system has acquired your doctor's practice, their DEXA scanner may be physically in the same building it always was, but it now bills under the hospital's outpatient facility fee structure. This is called site-neutral billing and it is one of the most common reasons patients see unexpectedly high bills for low-complexity imaging like bone density scans.
DEXA Scan Cost by Type in 2026
Three distinct scan types are commonly billed, each with a different scope and price point. Your doctor's order should specify which one is medically necessary. If your bill includes a more expensive code than what was ordered, that is a billing error worth disputing.
Typical cost by variant| Scan Type | What It Measures | Cash Price Range | 2026 Medicare PFS Rate |
|---|
| 77080 — Axial DEXA (hip and spine) | Bone density at hip and lumbar spine; standard osteoporosis screening | $100 – $300 | ~$40 non-facility |
| 77081 — Peripheral DEXA (wrist, heel, or finger) | Bone density at peripheral sites; often used as initial screening tool | $65 – $150 | ~$27 non-facility |
| 77085 — Axial DEXA with vertebral fracture assessment (VFA) | Bone density plus imaging of the spine to detect existing fractures | $150 – $400 | ~$53 non-facility |
77080 and 77085 cannot be billed together on the same day without a modifier — 77085 includes the axial bone density component. If both appear on one claim without modifier XU, that is a coding error.

What Medicare Pays for DEXA Scan
Medicare Part B covers bone mass measurements at no cost to the patient every 24 months for beneficiaries who meet at least one of five eligibility criteria: (1) women who are estrogen-deficient and at clinical risk for osteoporosis; (2) anyone whose X-rays show possible bone loss or vertebral fractures; (3) anyone taking prednisone or other corticosteroids for more than three months; (4) anyone diagnosed with primary hyperparathyroidism; or (5) anyone currently on an FDA-approved osteoporosis drug requiring monitoring. When your provider accepts Medicare assignment, you pay $0 and the Part B deductible does not apply. This is one of the few Medicare-covered services with no cost sharing.
If you need a DEXA scan more frequently than every 24 months, your doctor must document medical necessity. In that case, standard Part B cost sharing applies: 20% coinsurance after the 2026 Part B deductible of $283. Medicare Advantage plans must cover the same preventive bone density services at no cost, though rules for additional scans vary by plan. If you have Medicare and are unsure whether your scan qualifies for $0 coverage, ask your provider to confirm the billing code and diagnosis code before the appointment.
What Factors Affect Cost
- Site of service: hospital outpatient departments charge 2 to 4 times more than independent imaging centers or physician offices for the same scan.
- Scan type ordered: an axial DEXA with vertebral fracture assessment (77085) costs more than a standard axial DEXA (77080), which costs more than a peripheral scan (77081).
- Whether you meet Medicare or private insurance preventive coverage criteria: meeting criteria means $0 out of pocket; failing to meet them means standard cost sharing applies.
- Insurance deductible status: if you haven't met your annual deductible, you pay the full allowed amount, not just a copay.
- Geographic region: urban markets and high-cost states like California, New York, and Hawaii average $50 to $100 more than smaller metro areas.
- Hospital ownership of the imaging site: if a hospital has acquired a physician practice, the DXA machine may still be in the same office building but now bills under hospital facility rates.
Common DEXA Scan Billing Errors
Bone density scan claims are relatively straightforward, but a few specific errors appear regularly. Check your Explanation of Benefits or itemized bill for these before paying:
- 77080 and 77085 billed together without modifier XU: 77085 already includes the axial bone density scan, so billing both without a valid reason is a bundling error and a common denial trigger.
- Hospital facility fee billed for a scan performed in a freestanding office: if your scan took place at a physician's office or standalone imaging center, you should not see a separate hospital facility charge.
- Frequency billing violation: Medicare covers one axial DEXA per 24 months for most patients. A second claim within that window without documented medical necessity will deny and should not be passed to you.
- Vertebral fracture assessment (77085 component) billed when only a standard bone density scan was performed: if your order did not include a vertebral fracture assessment, that component should not appear on your bill.
- Deductible applied when coverage should be $0: if you met Medicare's osteoporosis screening criteria and your provider accepted assignment, your bill should be $0. A deductible charge is incorrect.
Frequently Asked Questions
How much does a DEXA scan cost without insurance in 2026?
Without insurance, a DEXA bone density scan typically costs $80 to $300 in 2026. The national average is around $175. Independent imaging centers and physician offices charge $100 to $200 for a standard axial DEXA (hip and spine). Hospital outpatient departments charge $200 to $600 for the same test. Always call ahead and ask for the self-pay rate before scheduling.
Does Medicare cover DEXA scans for free?
Yes, for eligible beneficiaries. Medicare Part B covers bone mass measurements at $0 cost to the patient every 24 months when you meet at least one qualifying condition: being an estrogen-deficient woman at risk for osteoporosis, having X-ray signs of bone loss, taking corticosteroids for more than three months, having primary hyperparathyroidism, or monitoring an osteoporosis medication. Your provider must accept Medicare assignment. If you meet the criteria, the Part B deductible also does not apply.
How often does Medicare cover a bone density test?
Medicare covers a bone density scan (DEXA) once every 24 months for qualifying individuals. If your doctor determines you need the scan more frequently, they must document the medical necessity. In that case, standard Part B cost sharing applies: 20% coinsurance after meeting the $283 Part B deductible for 2026.
What is the difference between a DEXA scan at a hospital versus an imaging center?
The scan itself is clinically identical. The difference is purely in billing. Hospital outpatient departments charge facility fees that reflect overhead across the entire hospital, pushing cash prices to $200 to $600. Independent imaging centers and physician offices charge $100 to $200 for the same test. The 2026 Medicare rates confirm the gap: ~$40 at non-facility settings vs. ~$107 under the hospital OPPS rate.
What does a DEXA scan measure?
A DEXA scan measures bone mineral density using two low-dose X-ray beams at different energy levels. The result is a T-score that compares your bone density to a healthy young adult. A T-score at or below -2.5 indicates osteoporosis. Between -1.0 and -2.5 indicates osteopenia (low bone density). Above -1.0 is considered normal. A Z-score is also generated, comparing your density to others of your age and sex.
Do private insurance plans cover DEXA scans?
Most private insurance plans cover DEXA scans as preventive care for women 65 and older and for postmenopausal women under 65 with risk factors such as low body weight, smoking history, or family history of osteoporosis. Many plans cover the scan annually for high-risk individuals. Coverage rules vary by insurer and plan, so confirm with your carrier before scheduling. If the scan is diagnostic rather than preventive, standard cost sharing typically applies.
What is the No Surprises Act protection for DEXA scans?
Under the No Surprises Act, if you are uninsured or self-pay, any provider or facility must give you a Good Faith Estimate of the expected cost before your DEXA scan. The estimate must be provided at least one business day before your scheduled appointment. If the final bill exceeds the Good Faith Estimate by more than $400, you have the right to use the patient-provider dispute resolution process. Ask for the Good Faith Estimate when you call to schedule.
What is the difference between 77080, 77081, and 77085?
77080 is the standard axial DEXA, measuring bone density at the hip and spine. This is the most commonly ordered code for osteoporosis screening. 77081 is a peripheral scan of sites like the wrist, heel, or finger, often used as an initial screening tool. 77085 is an axial DEXA that also includes a vertebral fracture assessment, adding imaging of the spine to detect existing fractures. 77080 and 77085 cannot be billed together on the same claim without modifier XU, because 77085 already includes the axial bone density component.
