Myositis ossificans progressiva, unspecified lower leg
ICD-10 M61.169 is a billable code used to indicate a diagnosis of myositis ossificans progressiva, unspecified lower leg.
Myositis ossificans progressiva (MOP) is a rare genetic disorder characterized by the abnormal formation of bone in muscles and connective tissues. This condition typically manifests in early childhood and progresses over time, leading to significant muscle weakness and restricted mobility. In the case of unspecified lower leg involvement, the ossification occurs in the muscles of the lower leg, which can severely impact a patient's ability to walk and perform daily activities. The condition is caused by mutations in the ACVR1 gene, which plays a crucial role in bone growth and development. Patients may experience episodes of swelling, pain, and stiffness in the affected muscles, followed by the gradual development of bone tissue in these areas. Diagnosis is often confirmed through imaging studies, such as X-rays or MRI, which reveal the presence of heterotopic ossification. Management of MOP focuses on symptomatic relief, physical therapy, and avoiding trauma to the affected areas, as injury can exacerbate ossification. Due to the progressive nature of the disease, ongoing monitoring and supportive care are essential to maintain function and quality of life.
Detailed clinical notes including patient history, physical examination findings, and imaging results.
Patients presenting with muscle pain and swelling, followed by restricted mobility.
Ensure genetic testing results are included in documentation to support diagnosis.
Surgical notes if applicable, imaging studies, and rehabilitation plans.
Management of complications related to ossification, such as joint stiffness.
Document any surgical interventions or physical therapy referrals.
Used for initial assessment of mobility and function in patients with myositis ossificans progressiva.
Detailed evaluation notes including range of motion and functional limitations.
Physical therapists should document specific interventions and patient responses.
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 evaluation, imaging studies showing heterotopic ossification, and genetic testing for ACVR1 mutations.
