Code Classification

  • Diseases of the musculoskeletal system and connective tissue
    (M00–M99)
    • Other osteopathies
      (M86-M90)
      • Osteonecrosis
        (M87)

M87.9 is a billable diagnosis code used to specify a medical diagnosis of osteonecrosis, unspecified. The code is valid during the current fiscal year for the submission of HIPAA-covered transactions from October 01, 2023 through September 30, 2024.

Unspecified diagnosis codes like M87.9 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.

Clinical Classification

Clinical Information

  • Bisphosphonate-Associated Osteonecrosis of the Jaw

    necrotic jaws or other maxillofacial skeleton necrosis associated with bisphosphonate use (see bisphosphonates). injury, dental procedures, and trauma can trigger the necrotic process.
  • Osteonecrosis

    death of a bone or part of a bone, either atraumatic or posttraumatic.
  • Aseptic Necrosis of Bone

    necrosis of bone due to an inadequate blood supply.

Inclusion Terms

Inclusion Terms
These terms are the conditions for which that code is to be used. The terms may be synonyms of the code title, or, in the case of "other specified" codes, the terms are a list of the various conditions assigned to that code. The inclusion terms are not necessarily exhaustive. Additional terms found only in the Alphabetic Index may also be assigned to a code.
  • Necrosis of bone NOS

Index to Diseases and Injuries References

The following annotation back-references for this diagnosis code are found in the injuries and diseases index. The Index to Diseases and Injuries is an alphabetical listing of medical terms, with each term mapped to one or more ICD-10-CM code(s).

Convert M87.9 to ICD-9-CM

  • ICD-9-CM Code: 733.40 - Asept necrosis bone NOS
    Approximate Flag - The approximate mapping means there is not an exact match between the ICD-10 and ICD-9 codes and the mapped code is not a precise representation of the original code.

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.

Osteonecrosis

Osteonecrosis happens when blood flow to part of a bone is reduced. This can lead to death of bone tissue, causing the bone to break down and joints to collapse.
