M93 is a non-specific and non-billable diagnosis code code, consider using a code with a higher level of specificity from the list below for a diagnosis of other osteochondropathies. The code is not specific and is NOT valid for the year 2026 for the submission of HIPAA-covered transactions. Category or Header define the heading of a category of codes that may be further subdivided by the use of 4th, 5th, 6th or 7th characters.

Specific Coding Applicable to Other osteochondropathies

Non-specific codes like M93 require more digits to indicate the appropriate level of specificity. Consider using any of the following billable codes with a higher level of specificity when coding for other osteochondropathies:

  • M93.0 for Slipped upper femoral epiphysis (nontraumatic)

  • M93.00 for Unspecified slipped upper femoral epiphysis (nontraumatic)

  • M93.01 for Acute slipped upper femoral epiphysis, stable (nontraumatic)

  • M93.02 for Chronic slipped upper femoral epiphysis, stable (nontraumatic)

  • M93.03 for Acute on chronic slipped upper femoral epiphysis, stable (nontraumatic)

  • M93.04 for Acute slipped upper femoral epiphysis, unstable (nontraumatic)

  • M93.05 for Acute on chronic slipped upper femoral epiphysis, unstable (nontraumatic)

  • M93.06 for Acute slipped upper femoral epiphysis, unspecified stability (nontraumatic)

  • M93.07 for Acute on chronic slipped upper femoral epiphysis, unspecified stability (nontraumatic)

  • Use M93.1 for Kienbock's disease of adults

  • M93.2 for Osteochondritis dissecans

  • Use M93.20 for Osteochondritis dissecans of unspecified site

  • M93.21 for Osteochondritis dissecans of shoulder

Tabular List of Diseases and Injuries

The following annotation back-references are applicable to this diagnosis code. The Tabular List of Diseases and Injuries is a list of ICD-10-CM codes, organized "head to toe" into chapters and sections with coding notes and guidance for inclusions, exclusions, descriptions and more.


Type 2 Excludes

Type 2 Excludes
A type 2 excludes note represents "Not included here". An excludes2 note indicates that the condition excluded is not part of the condition represented by the code, but a patient may have both conditions at the same time. When an Excludes2 note appears under a code, it is acceptable to use both the code and the excluded code together, when appropriate.
  • osteochondrosis of spine M42

Patient Education


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
