M90.51
Osteonecrosis in diseases classified elsewhere, shoulder
Clinical Classification Guidelines
Medical Intelligence & Overview
Osteonecrosis of the shoulder, also known as avascular necrosis, is a condition where blood flow to the shoulder bone (humerus or scapula) is interrupted, leading to bone tissue death. Classified under ICD-10 code M90.51, this condition can cause joint pain, limited movement, and if left untreated, significant shoulder dysfunction. It often occurs as a complication of other illnesses but can also develop independently. Early diagnosis and management are key to preventing joint destruction and improving quality of life.
Causes & Symptoms
Clinical Causes: Trauma or injury to the shoulder, such as fractures or dislocations Prolonged use of high-dose corticosteroids or certain medications Excessive alcohol consumption Blood disorders like sickle cell anemia or hemoglobinopathies Certain medical conditions like rheumatoid arthritis or lupus Decompression sickness in divers Radiation therapy to the shoulder area Other underlying diseases that impair blood supply to the bone
Key Symptoms: Deep, aching shoulder pain that worsens with activity Limited range of motion or stiffness in the shoulder joint Swelling around the shoulder Weakness in the shoulder and arm Pain that may worsen when lying on the affected side Possible muscle wasting in the shoulder region in advanced stages Gradual loss of shoulder joint function, leading to difficulty in movement
Diagnostic & Treatment
Diagnosis Path: Medical history review and physical examination Imaging tests such as X-rays to visualize bone damage Magnetic Resonance Imaging (MRI) for detailed assessment of bone and soft tissues Bone scans to detect areas of low blood flow Blood tests to identify underlying conditions contributing to blood flow issues Biopsy, in some cases, to rule out other causes of bone destruction
Treatment Protocols: Medications to relieve pain and inflammation, such as NSAIDs Reducing activities that exacerbate symptoms Physical therapy to maintain shoulder mobility and strength Assisting devices like braces or slings to stabilize the shoulder Core decompression: a surgical procedure to reduce intraosseous pressure and promote blood flow Bone grafts or joint replacement surgery in advanced cases Treating underlying conditions contributing to osteonecrosis to prevent progression
Clinical Advice & FAQs

Is M90.51 a billable ICD-10 code?
Yes, M90.51 is a specific, billable code that can be used to indicate a diagnosis for reimbursement purposes.
Documentation
How do I report M90.51?
