Myositis ossificans progressiva, right thigh
ICD-10 M61.151 is a billable code used to indicate a diagnosis of myositis ossificans progressiva, right thigh.
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 with progressive muscle stiffness and weakness, often beginning in childhood or early adulthood. In the case of M61.151, the ossification occurs specifically in the right thigh, leading to significant functional impairment. Patients may experience episodes of swelling and pain in the affected area, which can be mistaken for muscle strain or injury. The condition is caused by mutations in the ACVR1 gene, which plays a crucial role in bone growth and development. Diagnosis is primarily clinical, supported by imaging studies such as X-rays or MRI that reveal the presence of 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 essential for accurate coding and appropriate patient management.
Detailed clinical notes including symptom onset, progression, and response to treatment.
Patients presenting with muscle stiffness and pain, particularly after minor trauma.
Documentation should clearly differentiate MOP from other inflammatory myopathies.
Imaging studies and surgical notes if intervention is considered.
Patients with progressive loss of mobility due to ossification.
Consideration of the risks associated with surgical procedures in patients with MOP.
Used to evaluate the extent of ossification in the right thigh.
Include imaging results and clinical findings.
Orthopedic specialists should document the rationale for imaging.
