M87.26
Osteonecrosis due to previous trauma, tibia and fibula
Clinical Classification Guidelines
Medical Intelligence & Overview
Osteonecrosis, also known as avascular necrosis, is a condition where bone tissue begins to die due to a lack of blood supply. When this occurs in the tibia and fibula—the bones in the lower leg—it often results from previous trauma or injury. The ICD-10 code M87.26 specifically refers to osteonecrosis of these bones caused by past trauma. This condition can lead to pain, swelling, and joint dysfunction if not diagnosed and managed appropriately.
Causes & Symptoms
Clinical Causes: Previous traumatic injury to the lower leg, such as fractures or severe blows Complications from orthopedic surgeries or procedures in the area Repeated microtrauma from overuse or stress Vascular injury disrupting blood flow to the tibia and fibula Underlying medical conditions affecting blood supply, such as blood clotting disorders
Key Symptoms: Localized pain in the lower leg, especially during weight-bearing activities Swelling or tenderness over the affected bones Limited range of motion or stiffness in the nearby joints Possible sensations of numbness or tingling if nerve involvement occurs Weakness or instability in the leg In severe cases, there may be visible deformity or bone collapse
Diagnostic & Treatment
Diagnosis Path: X-rays to identify bone changes such as collapse or sclerosis Magnetic resonance imaging (MRI) for detailed visualization of bone marrow and early changes Bone scans to assess blood flow and detect areas of decreased activity Patient history review focusing on past trauma or injury Physical examination to assess swelling, deformity, and functional limitations
Treatment Protocols: Nonsteroidal anti-inflammatory drugs (NSAIDs) to reduce pain and inflammation Rest and activity modification to prevent further injury Physical therapy to strengthen surrounding muscles and improve mobility Surgical intervention in advanced cases, such as core decompression, bone grafting, or joint replacement Use of assistive devices like braces or crutches for support during recovery Management of underlying medical conditions that may impair blood flow
Clinical Advice & FAQs

Yes, M87.26 is a specific, billable code that can be used to indicate a diagnosis for reimbursement purposes.
Documentation
How do I report M87.26?
