    ICD-10-CM Code For Osteonecrosis: Group Overview

    The International Classification of Diseases, Tenth Revision, Clinical Modification (ICD-10-CM) code group M87 includes diagnoses for osteonecrosis, avascular necrosis, and related conditions characterized by bone ischemia and structural collapse. These ICD-10-CM diagnosis codes are used to document specific affected sites, disease severity, and any underlying causes or complications that influence treatment planning. Accurate coding within the ICD-10-CM M87 group supports proper claim adjudication, complete clinical documentation, and appropriate reimbursement.

    ICD-10-CM M87: Osteonecrosis Overview

    The diagnoses in this group represent bone death due to compromised blood supply, commonly affecting joints such as the hip, knee, and shoulder. These conditions target the musculoskeletal system and can lead to pain, collapse of bone structure, and secondary arthritis. Accurate coding matters for reimbursement because it documents disease severity, anatomical site, and any associated complications that influence payment and care planning.

    When to Use

    Use a code from this group when documentation indicates bone necrosis or avascular necrosis at a specific anatomical site, including laterality and any identified underlying cause. Select codes that reflect disease stage, associated collapse or arthritis, and any concurrent conditions noted in the clinical record.

    Typical Clinical Scenarios

    • A middle-aged patient with progressive groin pain and reduced hip range of motion who reports months of worsening symptoms and difficulty weight-bearing; imaging (MRI) shows collapse of the femoral head consistent with idiopathic avascular necrosis of the femoral head, and the clinician documents osteonecrosis of the right femoral head as a chronic degenerative process. Typical codes: M87.051, M87.052
    • An adult on long‑term corticosteroid therapy for systemic lupus presents to the emergency department with sudden severe shoulder pain after minimal trauma; radiographs and MRI reveal subchondral collapse of the humeral head indicative of steroid‑associated osteonecrosis, prompting urgent orthopedic evaluation for potential surgical intervention. Typical codes: M87.031, M87.032
    • An elderly patient with a history of total hip arthroplasty develops worsening pain and radiographic evidence of bone death in the acetabulum adjacent to the prosthesis, recorded as post‑surgical osteonecrosis contributing to device failure and considered a comorbidity affecting management. Typical codes: M87.241, M87.242
