Using Dual Energy X-ray Absorption (DEXA), this examination is used to measure Bone Mineral Density (BMD). The most common cause for loss of bone density is osteoporosis.
Given that women lose bone from about the age of 45 (linked with Oestrogen production falling), a Bone Density Scan that enables a like for like comparison over time is useful to alert patients and provide time for them to minimise risks of Osteoporosis.
While there is no specific preparation required for this examination, patients must bring their previous examination films/images from other providers and even if we did the previous Bone Density examination. This is important to help our Radiographers plan where the scanning lines will be located.
A thin beam of x-ray energy is passed through the lower spine and hip regions. A computer calculates how much of x-ray energy is absorbed by the bones and compares the results with what is expected in a young (20 year old) person, and also with what is expected for a person of your age, sex and race. The results are plotted on a graph, and a report given by the radiologist.
The result will be given as a T-Score where a result > -1 is normal, a score between -1 and -2.5 would mean Osteopenia and a score below -2.5 would mean Osteoporosis.
The use of consistent scanning protocols and equipment help deliver a more valuable picture for patients.
The Government uses rules to determine if rebates offered by Medicare and the Department of Veterans Affairs can be accessed by patients. To be eligible for such a rebate patients must meet one of the following criteria, and such criteria must be indicated on the referral, ideally with the relevant Medicare item Number.
One service only in a 24 month period if performed for:
One service only in a 12 month period if performed for:
One service only in a 24 month period if performed for diagnosis and monitoring of bone loss associated with one or more of the following:
If performed 12 months following a significant change in therapy for established low bone mineral density. (Change in class of drugs rather than change in dose regime, or confirmation of a presumptive diagnosis of low bone mineral density made on the basis of 1 or more fractures occurring after minimal trauma.)
Bone densitometry, using dual energy X‑ray absorptiometry or quantitative computed tomography, involving the measurement of 2 or more sites (including interpretation and reporting) for the measurement of bone mineral density, in a patient aged 70 years or over if:
(a) the patient has not had previous bone densitometry testing; or
(b) the patient has bone mineral density as measured by a t‑score of ‑1.5 or above; other than a service associated with a service to which item 12306, 12312, 12315, 12321 or 12322 applies For any particular patient, once only in a 5 year period.
(a) the patient is 70 years of age or over; and
(b) the patient has bone mineral density as measured by a t‑score of less than between ‑1.5 or above ‑2.5; other than a service associated with a service to which item 12306, 12312, 12315, 12320 or 12321 applies For any particular patient, once only in a 2 year period.
Includes all other indications. No Medicare Benefit is applicable. Our normal fee applies.
