M85.80 is a billable code used to specify a medical diagnosis of other specified disorders of bone density and structure, unspecified site. The code is valid for the year 2020 for the submission of HIPAA-covered transactions. The ICD-10-CM code M85.80 might also be used to specify conditions or terms like acroosteolysis, apophyseal sclerosis, bone density above reference range, craniofacial dysplasia osteopenia syndrome, disorder with defective osteoid mineralization, dysplasia with decreased bone density, etc

Short Description:Oth disrd of bone density and structure, unspecified site

Information for Patients

Bone Density

Strong bones are important for your health. A bone mineral density (BMD) test is the best way to measure your bone health. It compares your bone density, or mass, to that of a healthy person who is the same age and sex as you are. It can show

  • Whether you have osteoporosis, a disease that makes your bones weak
  • Your risk for breaking bones
  • Whether your osteoporosis treatment is working

Low bone mass that is not low enough to be osteoporosis is sometimes called osteopenia. Causes of low bone mass include family history, not developing good bone mass when you are young, and certain conditions or medicines. Not everyone who has low bone mass gets osteoporosis, but they are at higher risk for getting it.

If you have low bone mass, there are things you can do to help slow down bone loss. These include eating foods rich in calcium and vitamin D and doing weight-bearing exercise such as walking, tennis, or dancing. In some cases, your doctor may prescribe medicines to prevent osteoporosis.

Bone Diseases

Your bones help you move, give you shape and support your body. They are living tissues that rebuild constantly throughout your life. During childhood and your teens, your body adds new bone faster than it removes old bone. After about age 20, you can lose bone faster than you make bone. To have strong bones when you are young, and to prevent bone loss when you are older, you need to get enough calcium, vitamin D, and exercise. You should also avoid smoking and drinking too much alcohol.

Bone diseases can make bones easy to break. Different kinds of bone problems include

  • Low bone density and osteoporosis, which make your bones weak and more likely to break
  • Osteogenesis imperfecta makes your bones brittle
  • Paget's disease of bone makes them weak
  • Bones can also develop cancer and infections
  • Other bone diseases, which are caused by poor nutrition, genetics, or problems with the rate of bone growth or rebuilding
