Myositis ossificans progressiva, lower leg
ICD-10 M61.16 is a billable code used to indicate a diagnosis of myositis ossificans progressiva, lower leg.
Myositis ossificans progressiva (MOP) is a rare genetic disorder characterized by the abnormal formation of bone in muscles, tendons, and other connective tissues. This condition typically presents in childhood or early adulthood and is caused by mutations in the ACVR1 gene, which plays a crucial role in bone growth and development. In the lower leg, patients may experience progressive muscle weakness, stiffness, and pain due to the ossification of muscle tissue. The condition often leads to significant functional impairment, as the formation of bone in soft tissues restricts movement and can result in joint deformities. Diagnosis is primarily clinical, supported by imaging studies such as X-rays or MRI, which reveal the characteristic heterotopic ossification. Management is symptomatic and may include physical therapy, pain management, and surgical intervention in severe cases. However, surgery is approached with caution due to the risk of exacerbating the condition. Understanding the complexities of MOP is essential for accurate coding and effective patient management.
Detailed clinical notes including history, physical examination findings, and treatment plans.
Patients presenting with muscle pain and stiffness, particularly after trauma.
Documentation should clearly differentiate MOP from other inflammatory myopathies.
Imaging results, surgical notes, and post-operative care documentation.
Patients requiring surgical intervention for severe ossification.
Careful documentation of surgical risks due to the nature of the condition.
Used when joint aspiration is needed due to complications from MOP.
Document the indication for the procedure and any imaging findings.
Orthopedic specialists should ensure clear documentation of the relationship between the procedure and MOP.
Myositis ossificans progressiva is a rare genetic disorder characterized by the abnormal formation of bone in muscles and connective tissues, leading to progressive disability.
Diagnosis is based on clinical presentation, family history, and imaging studies that reveal heterotopic ossification.
Treatment focuses on symptom management, physical therapy, and, in severe cases, surgical intervention, although surgery carries risks.
