Bone (mineral) density studies are used to evaluate diseases of bone and/or the responses of bone diseases to treatment. The studies access bone mass or density associated with such diseases as osteoporosis, osteomalacia, and renal osteodystrophy. Various single or combined methods of measurement may be required to: (a) diagnose bone disease, (b) monitor the course of bone changes with disease progression, or (c) monitor the course of bone changes with therapy.
Covered methods for measuring bone mineral density include:
• Single energy x-ray absorptiometry (SEXA)
• Dual energy x-ray absorptiometry (DXA)
• Quantitative computed tomography (QCT)
• Bone ultrasound densitometry (BUD)
• Photodensitometry
• Radiographic absorptiometry (RA)
The following bone mass measurements are NOT covered under Medicare because they are not considered reasonable and necessary under section 1862(a)(1)(A) of the Act:
• Single photon absorptiometry (SPA), Procedure code 78350 (effective 01/01/2007)
• Dual photon absorptiometry (DPA), Procedure code 78351.
Bone density can be measured at the wrist, spine, hip or calcaneus. The medical literature is divided on the accuracy of predicting osteoporosis of the spine or hip by measuring peripheral sites (wrist, calcaneus). It does appear, however, that measurement of bone density of the bone involved gives a better measurement of osteoporosis than does measurement of another bone not known to be involved.
Precise calibration of the equipment is required for accuracy and to reduce variation of test results and risk of misclassification of the degree of bone density. Lack of standardization in bone mineral measurement remains an issue, and tests are best done on the same suitably precise instrument to insure accuracy. It is important to use results obtained with the same scanner when comparing a patient to a control population, as systematic differences among scanners have been found. To ensure reliability of bone mass measurements, the densitometry technologist must have proper training in performing this procedure. Malpositioning of a patient or analyzing a scan incorrectly can lead to great errors in bone mineral density studies.
Indications:
Medicare considers a bone mineral density study to be medically reasonable and necessary for the following indications. In addition, all coverage criteria listed below must be met.
1. A patient with vertebral abnormalities as demonstrated by an x-ray to be indicative of osteoporosis, osteopenia (low bone mass), or vertebral fracture.
2. A patient being monitored to assess the response to or efficacy of an FDA-approved osteoporosis drug therapy. This service must be performed using dual energy x-ray absorptiometry system (axial skeleton) – Procedure codes 77080 and 77085.
3. A patient with known primary hyperparathyroidism.
4. A patient receiving (or expecting to receive) glucocorticoid (steroid) therapy equivalent to an average of 5.0 mg of prednisone or greater, per day, for more than 3 months.
5. A woman who has been determined by the physician or a qualified non physician practitioner treating her to be estrogen-deficient and at clinical risk for osteoporosis, based on her medical history and other findings.
NOTE: Since not every woman who has been prescribed estrogen replacement therapy (ERT) maybe receiving an “adequate” dose of the therapy, the fact that a woman is receiving ERT should not preclude her treating physician or other qualified treating nonphysician practitioner from ordering a bone mass measurement for her. If a bone mass measurement is ordered for a woman following a careful evaluation of her medical need, however, it is expected that the ordering/treating physician (or other qualified treating nonphysician practitioner) will document in her medical record why he or she believes that the woman is estrogen-deficient and at clinical risk for osteoporosis.
An estrogen-deficient woman qualifies if she is at clinical risk for osteoporosis, based on her medical history and other findings. Unless this applies and is documented in the medical record, the service is not payable.
In addition to gender and estrogen-deficiency, pertinent factors acceptable as documentation for the clinical risk include, but are not limited to: age, family history and personal history of fractures as an adult, race, bone structure and body weight, premature menopause, lifestyle, medications, chronic diseases, and other genetic and environmental factors. Symptoms and findings of osteoporosis include, but are not limited to: back pain, loss of height, curving spine, and chest x-ray showing osteopenia.
Bone density measurement is not a covered Medicare benefit when utilized for osteoporosis screening in an estrogen-deficient woman, who has not been determined by the physician or a qualified nonphysician practitioner treating her to be at clinical risk for osteoporosis, based on her medical history and other findings.
If – in addition to gender and estrogen-deficiency – a woman has been determined to be at clinical risk for osteoporosis, based on her history and other findings, and this has been appropriately documented in the medical record, this Carrier will interpret the menopausal state as symptomatic.
DESCRIPTION
Bone mineral density (BMD) can be measured with a variety of techniques in a variety of sites. Sites are broadly subdivided into central sites (e.g. hip or spine) and peripheral sites (e.g. wrist, finger, heel). While BMD measurements are predictive of fragility fractures at all sites, central measurements of the hip and spine are the most predictive. Additionally, fractures of the hip and spine (e.g. vertebral fractures) are the most clinically relevant. The most commonly used techniques are Dual X-ray Absorptiometry (DXA), Quantitative computed tomography (QCT), and Ultrasound Densitometry.
Dual-energy x-ray absorptiometry (DXA) is considered the gold standard because it is the most extensively validated test against fracture outcomes. In general, a central DXA BMD measurement should be strongly considered for initial screening purposes due to its reproducibility and ability to simultaneously establish the diagnosis of osteoporosis and provide a baseline if one is needed. This approach is endorsed by the National Osteoporosis Foundation’s Clinician’s Guide to Prevention and Treatment of Osteoporosis as well as the Michigan Quality Improvement Consortium Guideline:
Management and Prevention of Osteoporosis
Background:
Osteoporosis, defined as low bone mass leading to an increased risk of fragility fractures, is an extremely common disease in the elderly due to age-related bone loss in both sexes and menopause-related bone loss in women. Current practice guidelines published by the National Osteoporosis Foundation (NOF) recommend that measurement of bone mineral density (BMD) be performed in all women over the age of 65 and in postmenopausal women with additional risk factors. Additional risk factors include a personal history of fracture as an adult, history of fracture in a first-degree relative, current cigarette smoking, and low body weight .
BMD is one of the key determinants of the need for pharmacologic therapy. BMD is typically expressed in terms of the number of standard deviations (SD) the BMD falls below the mean for young, healthy adults. This number is termed the T score.
The NOF guidelines recommend that pharmacologic therapy be initiated in women with T scores below –2 in the absence of other risk factors, and in women with BMD T scores below –1.5 if other risk factors are present. Current pharmacologic options include hormone replacement therapy, bisphosphonates such as alendronate (Fosamax), selective estrogen receptor modulators (SERMs) such as raloxifene (Evista), and calcitonin. While BMD measurements are typically used to determinethe need for pharmacologic therapy, serial monitoring of BMD to determine treatment response is also performed.
Dual-energy x-ray absorptiometry (DXA) is considered the gold standard because it is the most extensively validated test against fracture outcomes. When used in the same patients, DXA machines from different manufacturers differ in the proportion of patients diagnosed to have osteoporosis by 6 to 15 percent. Published studies consistently show that the probability of receiving a diagnosis of osteoporosis depends on the choice of test and site. One analytical study, for example, found that
6 percent of women older than 60 years of age would receive a diagnosis of osteoporosis if DXA of the total hip were used as the only test, compared with 14 percent for DXA of the lumbar spine, 3 percent with quantitative ultrasonography, and 50 percent with quantitative computed tomography (Faulker, 1999).
A meta-analysis assessed 23 publications from 11 separate prospective cohort studies published before 1996. Nearly all of the data were from women in their late 60s or older. No studies of ultrasonography were included. The meta-analysis indicated that DXA at the femoral neck predicted hip fracture better than measurements at other sites, and was comparable to forearm measurements for predicting fractures at other sites. For bone density measurements at the femoral neck, the pooled relative risk per decrease of one SD in bone density was 2.6 (CI, 2.0-3.5). In direct comparisons, heel ultrasonography was slightly worse than but comparable to DXA of the hip in women older than 65 years of age). For both tests, a result in the osteoporotic range is associated with an increased short-term probability of hip fracture. No data compare DXA and ultrasonography for prediction of fracture in women younger than 65 years of age.

Billing Guidelines.
Each claim must be submitted with the diagnosis codes that reflect the condition of the patient, and indicate the reason(s) for which the service was performed. The patient’s medical record must document that the patient meets one of the requirements of a “qualified individual” as described in the guidelines below. Documentation must be available upon request. It is the responsibility of the provider to code to the highest level specified. The correct use of a diagnosis code listed, does not assure coverage of a service. The service must be reasonable and necessary in the specific case and must meet the criteria specified. BMM tests provided without an accompanying interpretation and report, as part of the test, will be denied as not medically necessary.
CPT 77085 should NOT be billed for screening and is not part of the Preventive Benefit. Member cost share will apply when medically necessary criteria are met.
The following two studies are not covered by Medicare:
* 78350: Bone density (bone mineral content) study, 1 or more sites; single photon absorptiometry
* 78351: Bone density (bone mineral content) study, 1 or more sites; dual photon absorptiometry Medicare covers a bone mass measurement for a beneficiary once every two years (if at least 23 months have passed since the month the last bone measurement was performed). The criteria for bone mass measurement every two years are listed below:
* It is performed with a bone densitometer, other than dual photon absorptiometry (DPA) or a bone sonometer (e.g., ultrasound) device that has been approved or cleared for marketing by the Food and Drug Administration (FDA).
* It is performed on a qualified individual for the purpose of identifying bone mass, detecting bone loss or determining bone quality. The term “qualified individual” means an individual who meets the medical indications for at least one of the criteria listed below:
o A woman who has been determined by the physician or qualified non-physician treating her to be estrogendeficient and at clinical risk for osteoporosis, based on her medical history and other indicators NOTE: Since not every woman who has been prescribed estrogen replacement therapy (ERT) maybe receiving an “adequate” dose of the therapy, the fact that a woman is receiving ERT should not preclude her treating physician or other qualified treating nonphysician practitioner from ordering a bone mass measurement for her. If a bone mass measurement is ordered for a woman following a careful evaluation of her medical need, however, it is expected that the ordering/treating physician (or other qualified treating nonphysician practitioner) will document in her medical record why he or she believes that the woman is estrogen-deficient and at clinical risk for osteoporosis.
o An individual with vertebral abnormalities as demonstrated by an x-ray to be indicative of osteoporosis, osteopenia (low bone mass), or vertebral fracture
o An individual receiving (or expecting to receive) glucocorticoid (steroid) therapy equivalent to 5 mg of Prednisone, or greater, per day for more than 3 months
o An individual with primary hyperparathyroidism
o An individual being monitored to assess the response to or efficacy of an FDA approved osteoporosis drug therapy. This service must be performed using dual energy x-ray absorptiometry system (axial skeleton) –
CPT code 77080 and 77085.
* If it is furnished by a qualified supplier or provider of such services, under at least general level of supervision of a physician.
* If the test is ordered by the individual’s physician or qualified non-physician practitioner, who is treating the beneficiary following an evaluation of the need for the measurement, including a determination as to the medically appropriate measurement to be used for the individual, and who uses the results in the management of the patient.
* The test is reasonable and necessary for diagnosing, treating or monitoring of a “qualified” individual as defined above.
For conditions specified below, Medicare will cover a bone mass measurement for a qualified beneficiary more frequently than every two years, if medically necessary. To be considered, at least eleven months must have elapsed since the previous bone mass measurement test. Such conditions are:
* Monitoring beneficiaries on long-term glucocorticoid (steroid) therapy, equal to 5 mg of Prednisone or greater, per day for more than three months.
* Follow up bone mineral density testing to assess FDA-approved osteoporosis drug therapy until a response to such therapy has been documented over time.
* Confirming baseline BMMs to permit monitoring of beneficiaries in the future.
Medicare will cover a confirmatory baseline bone mass measurement when it is performed with a dual energy x-ray absorptionmetry system (axial skeletal) to permit monitoring of beneficiaries in the future, if the initial test was performed with a technique that is different from the proposed monitoring method (for example, if the initial test was bone sonometry and the patient will be monitored with bone densitometry, a second test utilizing densitometry will be paid). If the initial bone mass measurement was performed by a dual-energy x-ray absorptionmetry system (axial skeletal), a confirmatory BMM is not covered.
Priority Health billing Guidelines
Priority Health will limit coverage for BMD studies to central DXA only. Any other BMD studies (e.g. peripheral, such as wrist, finger and heel) are not medically/clinically necessary and, therefore, not covered. BMD studies do not require prior authorization by Priority Health. Guidelines on the appropriate use of BMD include information from the National Osteoporosis Foundation and Priority Health’s guidelines in conjunction with the Michigan Quality Improvement Consortium.
A. A one-time measurement of BMD, using one method only, may be considered medically necessary to assess fracture risk and the need for pharmacologic
therapy in the following patients considered at risk for osteoporosis, who are also considering treatment to prevent osteoporotic fracture:
1. All women aged 65 and older regardless of risk factors.
2. Men or women with a fracture risk (10-year probability of fracture using FRAX of 9.3%)
a. A FRAX Assessment is done to identify patients for BMD testing when any of the following criteria are met:
i. Personal history of fracture as an adult
ii. History of fragility fracture in a first degree relative
iii. Estrogen deficiency at an early age (<45 br="" years="">
iv. Current cigarette smoking
v. Low body weight (<127 br="" lbs="" nbsp="">
vi. Alcohol 3 or more units per day
vii. Use of oral corticosteroid therapy for more than 3 months
viii. History of osteopenia or osteopenia diagnosed via x-ray
ix. History of Depro-Provera® use
x. Individuals who are at increased risk for fractures due to diseases, conditions or treatments including, but not limited to primary hyperparathyroidism, renal failure (patients on dialysis), decreased mineralization noted on other studies, lifelong low calcium intake, impaired vision, dementia, recent falls, low physical activity, poor health/frailty, and long-term anti-convulsant therapy ( e.g., phenytoin therapy). (Calculate FRAX @ http://www.shef.ac.uk/FRAX/index.aspx)
3. Individuals beginning or on glucocorticoid therapy, provided intervention is an option. The most commonly used glucocorticoids include prednisone,
prednisolone, betamethasone, dexamethasone and decadron.
4. Transplant patients
5. Men with hypogonadism or receiving androgen deprivation treatment.
6. Post menopausal women who present with fractures (to confirm diagnosis and determine disease severity).
B. If the initial BMD measurement was medically necessary as defined above, serial measurements of BMD to monitor treatment response may be considered
medically necessary when performed no more frequently than 24 months apart and when a change in treatment plan may be made based on BMD results. When the need for serial measurements is anticipated in high risk patients who are likely to require treatment, and for obtaining serial measurements, a central
DXA BMD measurement should be obtained, as treatment related changes in BMD are not observed at peripheral sites.
C. More frequent bone mass measurements may be considered medically necessary in any of the following circumstances:
1. Monitoring individuals on long-term glucocorticoid (steroid) therapy of more than 3 months duration; or
2. For a confirmatory baseline bone mass measurement to permit monitoring of individuals in the future if the initial bone mass test was performed with a
technique that is different from the proposed testing method;
or
3. Monitoring of individuals with uncorrected primary hyperparathyroidism.

When Bone Mineral Density Studies are covered
Initial or repeat bone mineral density (BMD) measurement is not indicated unless the results will influence treatment decisions.
An initial measurement of central (hip/spine) BMD using dual x-ray absorptiometry may be considered medically necessary to assess fracture risk and the need for harmacologic therapy in individuals who are considered at risk for osteoporosis. BMD testing may be indicated under the following conditions:
• Women age 65 and older, regardless of other risk factors;
• Men age 70 and older, regardless of other risk factors;
• Younger postmenopausal women about whom there is a concern based on their risk factors;
• Men age 50-70 about whom there is a concern based on their risk factors;
• Adults with a condition or taking a medication associated with low bone mass or bone loss.
Repeat measurement of central (hip/spine) BMD using dual x-ray absorptiometry for individuals who previously tested normal (does not require pharmacologic treatment) may be considered medically necessary at an interval not more frequent than every 3–5 years; the interval depends on patient risk factors.
Regular (not more frequent than every 2–3 years) serial measurements of central (hip/spine) BMD using dual x-ray absorptiometry to monitor treatment response may be considered medically necessary when the information will affect treatment decisions such as duration of therapy.
Peripheral measurement of BMD may be considered medically necessary:
• If the hip/spine or hip/hip cannot be done or the patient is over the table limit for weight;
• For hyperparathyroidism, where the forearm is essential for diagnosis
When Bone Mineral Density Studies are not covered
Bone mineral density studies are considered not medically necessary if the criteria listed above are not met.
Screening individuals who are at low risk for osteoporosis is considered not medically necessary.
Ultrasound technology to measure and interpret bone density at peripheral sites by any method is considered investigational.
Peripheral or appendicular bone density studies are considered not medically necessary except as noted above.
Dual x-ray absorptiometry (DXA) body composition studies are considered investigational.
Description of Procedure or Service
Bone density studies can be used to identify individuals with osteoporosis and monitor response to osteoporosis treatment, with the goal of reducing the risk of fracture. Bone density is most commonly evaluated with dual x-ray absorptiometry (DXA); other technologies are also available. Risk factors for fracture include low bone mass, low bone strength, a personal history of fracture as an adult, or a history of fracture in a first-degree relative. Osteoporosis, defined as low bone mass leading to an increased risk of fragility fractures, is an extremely common disease in the elderly due to agerelated bone loss and/or menopause-related bone loss. Conditions that can cause or contribute to osteoporosis include lifestyle factors such as low intake of calcium, high intake of alcohol or cigarette smoking, and thinness. Other risk factors for osteoporosis include certain endocrine, hematologic, gastrointestinal tract and genetic disorders, hypogonadal states, and medications. Low bone mineral density (BMD) is a primary indication for pharmacologic therapy. Current pharmacologic options include bisphosphonates such as alendronate (i.e., Fosamax), selective estrogen receptor modulators (SERMs) such as raloxifene (i.e., Evista), the recombinant human parathyroid hormone teriparatide (Forteo), and calcitonin.
Bone mineral density can be measured with a variety of techniques in a variety of central (i.e., hip or spine) or peripheral (i.e., wrist, finger, heel) sites. While BMD measurements are predictive of fragility fractures at all sites, central measurements of the hip and spine are the most predictive. Fractures of the hip and spine (i.e., vertebral fractures) are also considered to be the most clinically relevant. BMD is typically expressed in terms of the number of standard deviations (SD) the BMD falls below the mean for young healthy adults. This number is termed the T score. The following technologies are most commonly used to measure BMD.
Dual X-ray Absorptiometry (DXA)
DXA is probably the most commonly used technique to measure bone mineral density, because of its ease of use, low radiation exposure, and its ability to measure BMD at both the hip and spine. DXA can also be used to measure peripheral sites, such as the wrist and finger. DXA uses two x-ray beams of different energy levels to scan the region of interest and measure the attenuation as the low- and highenergy beams pass through the bone and soft tissue. The low-energy beam is preferentially attenuated by bone, while the high-energy beam is attenuated by both bone and soft tissue. This differential attenuation between the two beams allows for correction for the irregular masses of soft tissue, which surround the spine and hip and therefore the measurement of bone density at those sites.
Whole body dual X-ray absorptiometry (DXA) uses x-rays of two different energy levels to measure lean tissue mass and total and regional body fat as well as bone density.
Quantitative Computed Tomography (QCT)
QCT depends on the differential absorption of ionizing radiation by calcified tissue and is used for central measurements only. Compared to DXA, QCT is less readily available and associated with relatively high radiation exposure and relatively high cost.
Ultrasound Densitometry
Ultrasound densitometry is a technique for measuring BMD at peripheral sites, typically the heel but also the tibia and phalanges. Compared to osteoporotic bone, normal bone demonstrates higher attenuation of the ultrasound wave, and is associated with a greater velocity of the wave passing through bone. Ultrasound densitometry has no radiation exposure, and machines may be purchased for use in an office setting.
The above techniques dominate BMD testing. Single and dual photon absorptiometry and radiographic absorptiometry are now rarely used and may be considered obsolete.
NOTE: This policy does not address the use of DXA as a technique to screen for vertebral fractures. That application of DXA is addressed in a separate policy, Screening for Vertebral Fracture with Dual X-Ray Absorptiometry.

“There are many options, but one that often gets overlooked is posture. In fact, you might already be taller but you just don’t know it yet. There is a burgeoning generation of people that have become introduced to technology a lot sooner than their parents were. The popularity of laptops, phones, tablets, gaming devices and even heavy backpacks is causing Forward Head Posture (FHP). This posture problem causes the shoulders to come forward and the upper back to hunch so that a person appears shorter than they actually are. So even after the age of 21, a person can grow 2 – 6 inches just be participating in rigorous stretching exercises.” grow taller pills
