Medical Statement

Bone density measurement is a tool that can be used for routine preventive screening in groups at high risk of osteoporosis (every 2 years), for disease management in groups at moderate risk for osteoporosis (every 3 years) or for monitoring treatment in patients with known osteoporosis (every 2 years).                                                                                                   

1)    Bone density measurement for routine screening purposes is covered under the Preventive Benefit:

a)    For women 65 years or older every two (2) years or longer.

b)    In women ages of 55 – 64 years with a diagnosis of hyperthyroidism, hyperparathyroidism, severe malnutrition, intestinal malabsorption, bedridden, long-term systemic steroid use, prolonged BMI < 19 or any pathologic fracture as a screening test under the Preventive Benefit every two (2) years. See BI062.

2)    Bone density measurement for disease management purposes is covered under the Medical Benefit:

a)    In women age 30 – 64 or men age ≥ 30 or more who have a medical indication that would suggest increased risk of osteoporosis, as a diagnostic test under the Medical Benefit every three (3) years or longer. If such an indication can be indicated on the claim with an appropriate ICD-10 diagnosis code, it should be so indicated. All cases may be reviewed prior to payment; if substantiating diagnosis is available, the claim will be paid without further investigation but if such information is not available, medical records may be requested. Potential indications for such a study would include:

1)    Bone density measurement for monitoring osteoporosis treatment under the Medical Benefit:

a)    Bone Density measurement may be indicated for the monitoring of changes in 

bone density for a person who is receiving treatment for an established diagnosis of osteoporosis (Tscore <-2.5) with or without pathologic fractures. This testing will be allowed every two (2) years. 

2)    In members under age 30, bone density testing requires pre-authorization.

1)    Bone mass measurement by dual photon absorptiometry (DPA) or ultrasound is considered experimental and investigational.

2)    Screening/evaluation of vertebral fractures with dual energy x-ray absorptiometry (DEXA or DXA, 77085 or 77086) (also known as morphometric x-ray absorptiometry) as an adjunct to bone mineral density measurement is considered experimental and investigational.  There is a lack of clinical trial evidence showing that patients with vertebral fractures on DXA but with bone mineral density levels above treatment thresholds benefit from pharmacologic treatment (BCBSA, 2004; BCBSA, 2005).  Note: Examples of vertebral fracture assessment application packages that have received 510(k) marketing clearance are the Instant Vertebral Assessment (IVA) (Hologic, Inc.) and Dual Energy Vertebral Assessment (DVA) (previously known as Lateral Vertebral Assessment (LVA) (GE Lunar Medical Systems). 

3)    Bone-material quality testing by microindentation (0547T) is considered experimental and investigational

4)    Bone strength & fracture risk using finite element analysis of functional data (0554T – 0557T) are considered experimental and investigational

5)    Bone density testing frequency:

a)    For women over the age of 65 or 55 – 64 at increased risk, every two (2) years (preventive).

b)    For women or men with an established diagnosis of osteoporosis (M81.0, M81.8) every two (2) years (medical).

c)    For any other indication, every three (3) years (medical).


1)    The following methods have been used as bone mass measurements of the axial or appendicular (peripheral) skeleton:

a)    Dual energy X-ray absorptiometry (DEXA or DXA);

b)    Single energy X-ray absorptiometry (SEXA);

c)     Single photon absorptiometry (SPA);

d)    Radiographic absorptiometry (photodensitometry);

e)    Quantitative computed tomography (QCT);

f)      Ultrasound bone mineral density studies (e.g., Sahara, SoundScan, Achilles + Bone Sonometer).

2)    DEXA has become the standard of care because of its accuracy, usefulness for measuring bone density at the highest risk sites (vertebra, hip), low radiation exposure, and low cost. 

3)    The QFracture risk score developed by the University of Nottingham is a validated tool designed to predict the fracture risk based on a number of different factors, including age, smoking status, BMI, presence of risk increasing diseases such as rheumatoid arthritis, and use of certain medications.  It may be used in men or women age 30-84 that have not had a previous osteoporotic fracture.

4)    Simple Calculated Osteoporosis Risk Estimation (S.C.O.R.E.) is a validated tool designed to predict postmenopausal women who are likely to have a T-score < -2 and should have screening performed. This tool was developed by the University of Washington School of Medicine (see:

5)    Some authorities have advocated annual bone mineral density screening.  The International Society for Clinical Densitometry, an association of providers with an interest in bone density measurement, recommends annual testing to detect continued bone loss in patients receiving treatment.  The position statement included a series of recommendations, but did not provide analysis to support these recommendations.  In addition, the American College of Radiology has recommended annual testing in patients receiving treatment.  However, the clinical literature on the accuracy and precision of bone density measurement does not support a recommendation for annual screening.  Erlichman & Holohan (1996) reviewed the literature on commonly used bone densitometry techniques, including DEXA.  They found that, although reviews of recent studies report DEXA accuracy error from 3 to 6 percent, other data indicate that DEXA accuracy error of ashed bone specimens of 9 percent.  (Measurements obtained by densitometers are compared with an independent standard measurement of bone mass, such as ashed bone sections.  The accuracy error is determined by how much the measurement varies from this accepted or "true" value.)  DEXA scans of the femur have a precision error from 0.5 percent to 3 percent.  Precision error is the variability in the measurements occurring with repeated measurements of the same object.  A technique`s precision is critical for serial measurements that correctly document bone loss over time.  Factors such as patient positioning, calibration and standardization procedures and differences in operator technique can result in large measurement variations.  The precision of measurements is reduced outside of the controlled conditions of a clinical trial setting.  The requisite minimum intervals between measurements that are necessary to reliably detect a reduction in bone mass are related to the precision attainable with current instruments and the rate of bone mass loss, assuming that the accuracy of the instrument is invariable.  If one assumed a 1 percent precision error, an annual rate of bone loss of 3 percent would be required to reliably detect bone mass loss after 1 year.  But Erlichman & Holohan (1996) explained that it is unlikely that yearly densitometry would be clinically indicated given the fact that 1 percent precision error is rarely attained and that a 3 percent annual loss in bone mass would be distinctly uncommon.  Precision errors in the range of 2 to 3 percent and annual bone mass losses of 1 to 2 percent are parameters more representative of published data.  In those instances, the minimum interval between densitometry measures necessary to document bone mass loss would be between 3.7 and 6 years.  Furthermore, there are no clinical data that demonstrate improved outcomes in osteoporosis patients who are screened annually.  Clinical trials of the bisphosphonate alendronates for the treatment of osteoporosis have found that failure to respond to therapy is a rare event.
