Finding a facility for a bone density test requires securing medical authorization and understanding the procedure. This diagnostic procedure, formally known as Dual-energy X-ray Absorptiometry (DEXA), uses a low-dose X-ray to measure the mineral content in your bones, typically at the hip and spine. DEXA scan results diagnose osteoporosis, a condition that weakens bones and increases the risk of fracture. The quick, non-invasive exam helps determine if preventative treatment is necessary. Planning ensures the procedure is covered by insurance and performed at an accredited location.
Securing the Necessary Medical Authorization
Obtaining a medical order or prescription is the first required step, as a physician must authorize the bone density test for it to be considered medically necessary and covered by insurance. Your Primary Care Provider (PCP) typically initiates this process, though a gynecologist, rheumatologist, or endocrinologist may also place the order. These professionals ensure the specialized imaging is appropriate for your individual risk factors.
Doctors use specific criteria to determine if a patient should receive a DEXA scan. Routine screening is generally recommended for all women aged 65 and older and men aged 70 and older, regardless of other risk factors. Younger postmenopausal women and men between 50 and 70 may also qualify if they have an elevated risk factor assessment. These risk factors can include a history of adult fracture, low body weight, current smoking, or a medical condition such as primary hyperparathyroidism.
The use of certain medications, particularly long-term oral corticosteroid therapy, is also a strong indicator for needing a bone density test due to their potential to accelerate bone loss. Your physician will combine your age, medical history, and specific risk factors to justify the need for a DEXA scan. Without a doctor’s referral confirming medical necessity, the test will likely be classified as an elective procedure, resulting in the denial of insurance coverage.
Identifying Appropriate Testing Facilities
Once the medical authorization is secured, the next step involves identifying an appropriate facility where the DEXA scan can be performed. The Dual-energy X-ray Absorptiometry equipment is typically housed in several types of medical settings, offering different levels of accessibility and scheduling convenience. The most common locations include hospital radiology departments, which often have advanced equipment and high capacity for various imaging needs.
Many patients find more specialized outpatient imaging centers to be a focused and sometimes faster option for scheduling and completing the test. These centers specialize in diagnostic imaging and frequently have dedicated DEXA machines with technicians who perform the procedure routinely. Another option, though less common, involves dedicated mobile screening units that travel to different clinics or community centers, offering increased local convenience.
You can begin your search by consulting your insurance provider’s directory, which lists in-network facilities that perform the procedure. Your referring physician’s office can also provide a list of local, trusted imaging partners. While searching online for local options is possible, always verify that the facility is accredited and accepts your specific insurance plan before booking an appointment.
Understanding Cost and Pre-Test Requirements
The financial and physical preparation aspects of a DEXA scan are essential for a smooth testing experience. For many individuals, especially those aged 65 and older, Medicare Part B covers the full cost of a bone mass measurement, provided the test is medically necessary and the facility accepts the Medicare assignment rate. Medicare typically allows for a covered scan once every 24 months, with more frequent testing possible for beneficiaries being monitored for an established condition or treatment effectiveness.
For those with private insurance, coverage is common but may involve a deductible or co-insurance payment, so it is important to contact your insurance company directly for a pre-authorization before scheduling. Without insurance coverage, the average out-of-pocket cost for a DEXA scan can vary widely but often falls in the range of $150 to $300 or more, depending on the facility and location. Confirming the billing codes and getting a good faith estimate from the imaging center prevents unexpected charges.
Preparing for the test day is straightforward and ensures the accuracy of the bone mineral density measurement. You should wear comfortable clothing that does not contain metal, such as zippers, buttons, or buckles, as these can interfere with the X-ray beam. It is necessary to temporarily stop taking any calcium supplements, including combination vitamins, for a minimum of 24 hours before the appointment. You must also inform the technician if you have recently undergone a test involving contrast dye, as residual material can impact results and may require a two-week delay.
