Code Classification

  • Diseases of the musculoskeletal system and connective tissue
    (M00–M99)
    • Other osteopathies
      (M86-M90)
      • Osteopathies in diseases classified elsewhere
        (M90)

M90.5 is a non-specific and non-billable diagnosis code code, consider using a code with a higher level of specificity for a diagnosis of osteonecrosis in diseases classified elsewhere. The code is not specific and is NOT valid for the year 2024 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 Osteonecrosis in diseases classified elsewhere

Non-specific codes like M90.5 require more digits to indicate the appropriate level of specificity. Consider using any of the following ICD-10-CM codes with a higher level of specificity when coding for osteonecrosis in diseases classified elsewhere:

  • Use M90.50 for Osteonecrosis in diseases classified elsewhere, unspecified site - BILLABLE CODE

  • M90.51 for Osteonecrosis in diseases classified elsewhere, shoulder - NON-BILLABLE CODE

  • Use M90.511 for Osteonecrosis in diseases classified elsewhere, right shoulder - BILLABLE CODE

  • Use M90.512 for Osteonecrosis in diseases classified elsewhere, left shoulder - BILLABLE CODE

  • Use M90.519 for Osteonecrosis in diseases classified elsewhere, unspecified shoulder - BILLABLE CODE

  • M90.52 for Osteonecrosis in diseases classified elsewhere, upper arm - NON-BILLABLE CODE

  • Use M90.521 for Osteonecrosis in diseases classified elsewhere, right upper arm - BILLABLE CODE

  • Use M90.522 for Osteonecrosis in diseases classified elsewhere, left upper arm - BILLABLE CODE

  • Use M90.529 for Osteonecrosis in diseases classified elsewhere, unspecified upper arm - BILLABLE CODE

  • M90.53 for Osteonecrosis in diseases classified elsewhere, forearm - NON-BILLABLE CODE

  • Use M90.531 for Osteonecrosis in diseases classified elsewhere, right forearm - BILLABLE CODE

  • Use M90.532 for Osteonecrosis in diseases classified elsewhere, left forearm - BILLABLE CODE

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.


Code First

Code First
Certain conditions have both an underlying etiology and multiple body system manifestations due to the underlying etiology. For such conditions, the ICD-10-CM has a coding convention that requires the underlying condition be sequenced first followed by the manifestation. Wherever such a combination exists, there is a "use additional code" note at the etiology code, and a "code first" note at the manifestation code. These instructional notes indicate the proper sequencing order of the codes, etiology followed by manifestation.
  • underlying disease, such as:
  • caisson disease T70.3
  • hemoglobinopathy D50 D64

Patient Education


Osteonecrosis

Osteonecrosis is a disease caused by reduced blood flow to bones in the joints. In people with healthy bones, new bone is always replacing old bone. In osteonecrosis, the lack of blood causes the bone to break down faster than the body can make enough new bone. The bone starts to die and may break down.

You can have osteonecrosis in one or several bones. It is most common in the upper leg. Other common sites are your upper arm and your knees, shoulders and ankles. The disease can affect men and women of any age, but it usually strikes in your thirties, forties or fifties.

At first, you might not have any symptoms. As the disease gets worse, you will probably have joint pain that becomes more severe. You may not be able to bend or move the affected joint very well.

No one is sure what causes the disease. Risk factors include :

  • Long-term steroid treatment
  • Alcohol misuse
  • Joint injuries
  • Having certain diseases, including arthritis and cancer

Doctors use imaging tests and other tests to diagnose osteonecrosis. Treatments include medicines, using crutches, limiting activities that put weight on the affected joints, electrical stimulation and surgery.
