A DEXA scan, formally known as Dual-energy X-ray Absorptiometry, is a medical imaging test that precisely measures the mineral content within your bones. This quick and non-invasive procedure serves as a standard tool for evaluating bone health, primarily focusing on bone mineral density (BMD). Healthcare providers utilize DEXA scans to diagnose conditions such as osteoporosis, a disease that causes bones to become fragile and more susceptible to fractures. The scan also helps assess an individual’s risk of future bone breaks and monitors the effectiveness of treatments aimed at improving bone strength.
Common Locations for DEXA Scans
DEXA scans are available at several types of medical facilities. Many hospitals house radiology or imaging departments equipped to perform these bone density tests. These departments often integrate DEXA scanning into a comprehensive suite of diagnostic imaging services.
Outpatient imaging centers are another common venue, specializing solely in diagnostic imaging. These dedicated centers frequently offer more flexible appointment times and may provide a quicker in-and-out experience compared to larger hospital settings. Additionally, some specialized medical clinics, such as orthopedic practices or endocrinology offices, maintain their own DEXA machines for patient convenience and integrated care.
Steps to Schedule Your Scan
Obtaining a DEXA scan typically begins with a referral from a healthcare professional, such as a primary care physician, orthopedist, or endocrinologist. This referral is generally required to establish medical necessity, ensuring the test is appropriate for your health needs, and to guide the interpretation of results. Your referring doctor can often provide recommendations for imaging centers or hospital departments that perform DEXA scans in your area.
To locate a suitable provider, you can utilize online search tools, consult your insurance company’s directory, or visit local hospital and imaging facility websites. Once you identify a facility, contact them directly to book your appointment. During this call, provide your referral and insurance details. Many facilities offer online scheduling portals, allowing electronic booking after a physician’s order.
Understanding Cost and Insurance
Costs for a DEXA scan vary. Most health insurance plans cover DEXA scans when medically necessary for diagnosing or monitoring bone conditions like osteoporosis. Always contact your insurance provider to confirm coverage details, including deductibles, co-pays, or co-insurance, to prevent unexpected charges.
Medicare Part B typically covers bone density tests every 24 months for preventive screening. More frequent scans due to medical conditions or ongoing treatment may also be covered if medically justified. Self-pay options are available for those without insurance or when coverage is not available, with costs typically ranging from $100 to $250, though some can exceed $700. Many facilities can provide a “good faith estimate” for self-pay patients, and some may accept Health Savings Account (HSA) or Flexible Spending Account (FSA) funds.
Preparing for and Undergoing Your Scan
Preparation for a DEXA scan is simple. Avoid calcium supplements for at least 24 hours before your appointment, as they can interfere with measurements. Wear loose, comfortable clothing without metal fasteners, zippers, or buttons, as metal can obstruct X-ray beams. Remove all jewelry, removable dental appliances, or metallic items.
During the procedure, you will lie still on a padded table while a scanning arm passes over your body, typically focusing on your lower spine and hips. The scan is painless and non-invasive, using very low doses of X-rays to measure bone density. The process is quick, usually 10 to 30 minutes, depending on the areas scanned. After the scan, images are sent to a radiologist for interpretation, and results are forwarded to your referring physician for discussion and follow-up.
