2020 ICD-10-CM Diagnosis Code M87

Osteonecrosis

    2016 2017 2018 2019 2020 Non-Billable/Non-Specific Code
  • M87 should not be used for reimbursement purposes as there are multiple codes below it that contain a greater level of detail.
  • The 2020 edition of ICD-10-CM M87 became effective on October 1, 2019.
  • This is the American ICD-10-CM version of M87 - other international versions of ICD-10 M87 may differ.

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. In most cases the manifestation codes will have in the code title, "in diseases classified elsewhere." Codes with this title are a component of the etiology/manifestation convention. The code title indicates that it is a manifestation code. "In diseases classified elsewhere" codes are never permitted to be used as first listed or principle diagnosis codes. They must be used in conjunction with an underlying condition code and they must be listed following the underlying condition.

Type 1 Excludes Help
A type 1 excludes note is a pure excludes. It means "not coded here". A type 1 excludes note indicates that the code excluded should never be used at the same time as M87. A type 1 excludes note is for used for when two conditions cannot occur together, such as a congenital form versus an acquired form of the same condition.

Clinical Information
  • A disorder characterized by necrotic changes in the bone tissue due to interruption of blood supply. Most often affecting the epiphysis of the long bones, the necrotic changes result in the collapse and the destruction of the bone structure.
  • Death of a bone or part of a bone
  • Death of a bone or part of a bone, either atraumatic or posttraumatic.
  • Death of bone tissue caused by loss of blood supply to the bone
  • Death of bone tissue due to traumatic or nontraumatic causes.
  • Necrotic changes in the bone tissue due to interruption of blood supply. Most often affecting the epiphysis of the long bones, the necrotic changes result in the collapse and the destruction of the bone structure.
  • Osteonecrosis occurs when your bones lose their blood supply. The bones die and eventually collapse, leading to pain and arthritis. 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. Early in the disease you might not have any symptoms. Later, you will probably have joint pain that becomes more severe as the disease gets worse. No one is sure what causes the disease. Risk factors include
    • long-term steroid treatment
    • alcohol abuse
    • joint injuries
    • having certain diseases, including arthritis and cancer
    treatments include medicines, using crutches, limiting activities that put weight on the affected joints, electrical stimulation and surgery. nih: national institute of arthritis and musculoskeletal and skin diseases
