Myositis ossificans progressiva, unspecified hand
ICD-10 M61.143 is a billable code used to indicate a diagnosis of myositis ossificans progressiva, unspecified hand.
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 is caused by mutations in the ACVR1 gene, leading to dysregulation of bone morphogenetic proteins (BMPs) that promote ossification. Patients with MOP typically present with progressive muscle weakness and stiffness, often beginning in childhood or early adulthood. The condition can lead to significant functional impairment, particularly in the hands, where ossification can restrict movement and dexterity. Symptoms may include swelling, pain, and limited range of motion in the affected areas. Diagnosis is primarily clinical, supported by imaging studies that reveal heterotopic ossification. Management focuses on symptomatic relief and physical therapy, as surgical intervention is often complicated by the risk of further ossification. Understanding the nuances of this condition is crucial for accurate coding and appropriate patient management.
Detailed clinical history, physical examination findings, and imaging results.
Patients presenting with muscle stiffness and pain, particularly after trauma.
Documentation must clearly differentiate MOP from other inflammatory myopathies.
Genetic testing results and family history of similar conditions.
Patients with a family history of ossification disorders or unexplained muscle weakness.
Genetic counseling documentation is essential for understanding inheritance patterns.
Used when joint aspiration is needed due to swelling from ossification.
Document the reason for aspiration and findings.
Rheumatology may require additional documentation on joint function.
Common symptoms include progressive muscle stiffness, pain, and limited range of motion, particularly in the affected areas.
