Z13.820 diagnosis code: Encounter for screening for osteoporosis

The Z13.820 is an ICD code included in the International Classification of Diseases, Tenth Revision, Clinical Modification (ICD-10-CM), and it is used to designate “Encounter for screening for osteoporosis.”

Based on the “screening” in the name of this ICD-10 code, you're probably wondering: “Can I really consider this as a diagnosis?”

To answer your question, no, this is not a diagnosis. It is considered to be unacceptable as a principal diagnosis. The reason for this is that, at the moment, the circumstance that a patient is undergoing is affecting their health; however, it is not because of a current illness or injury. In the context of this ICD-10 code, the cause could be osteoporosis.

Is the Z13.820 billable?

Yes, the Z13.820 ICD-10 code is billable and can be used to designate a patient for reimbursement purposes.

Z13.820 clinical information

The Z13.820 ICD-10 code is used for patients who undergo screening for osteoporosis, which is a bone condition characterized by the gradual embrittling of the bones to the point that they become so weak that simply bending over can fracture them.

Those who go to hospitals or clinics to get screened for osteoporosis will undergo bone density tests. These tests could be any of the following:

Dual-energy X-ray absorptiometry (DXA)
Quantitative computed tomography (QCT)
Biomechanical computed tomography (BCT)
Radiofrequency echographic multi spectrometry (REMS)

If a person is diagnosed with osteoporosis after the tests, treatment will likely include Bisphosphonates like alendronate and risedronate, bone-building drugs like Teriparatide and Abaloparatide, exercise, and having a healthy diet that includes getting enough calcium and vitamin D.

Do note that this ICD-10 code is only for screening. This doesn't mean that the person actually has osteoporosis.

Frequently asked questions

Is the ICD-10 code Z13.820 billable?

Yes, the ICD-10 code Z13.820 is a billable code used for encounters for screening for osteoporosis, following proper coding guidelines.

Who is at risk for osteoporosis?

People at risk for osteoporosis include postmenopausal women, older adults, and individuals with risk factors such as a family history of osteoporosis, low body weight, smoking, excessive alcohol consumption, low calcium intake, and certain medications.

Why is osteoporosis screening important?

Osteoporosis screening is important for early detection of low bone mineral density, which helps prevent fractures and supports timely intervention to improve bone health. A bone density study is essential for identifying individuals with an increased risk of fractures.
