Valid for Submission
M92.40 is a billable diagnosis code used to specify a medical diagnosis of juvenile osteochondrosis of patella, unspecified knee. The code M92.40 is valid during the fiscal year 2022 from October 01, 2021 through September 30, 2022 for the submission of HIPAA-covered transactions.
The ICD-10-CM code M92.40 might also be used to specify conditions or terms like juvenile osteochondrosis of primary patellar center or juvenile osteochondrosis of the secondary patellar center.
Unspecified diagnosis codes like M92.40 are acceptable when clinical information is unknown or not available about a particular condition. Although a more specific code is preferable, unspecified codes should be used when such codes most accurately reflect what is known about a patient's condition. Specific diagnosis codes should not be used if not supported by the patient's medical record.
The following clinical terms are approximate synonyms or lay terms that might be used to identify the correct diagnosis code:
- Juvenile osteochondrosis of primary patellar center
- Juvenile osteochondrosis of the secondary patellar center

Information for Patients
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
