Myositis ossificans progressiva, unspecified arm
ICD-10 M61.129 is a billable code used to indicate a diagnosis of myositis ossificans progressiva, unspecified arm.
Myositis ossificans progressiva (MOP) is a rare genetic disorder characterized by the abnormal formation of bone in muscles and connective tissues. This condition typically begins in early childhood and progresses over time, leading to significant muscle weakness and restricted mobility. In the case of unspecified arm involvement, the ossification occurs in the muscles of the arm, which can severely limit the range of motion and functional capabilities of the affected limb. Patients may experience episodes of swelling, pain, and stiffness in the affected muscles, which can be mistaken for other inflammatory or muscular disorders. The condition is caused by mutations in the ACVR1 gene, which plays a crucial role in bone development and regulation. Diagnosis is often made through clinical evaluation, imaging studies such as X-rays or MRI, and genetic testing. Management focuses on symptomatic relief, physical therapy, and avoiding trauma to the affected areas to prevent further ossification. Due to the progressive nature of the disease, ongoing monitoring and supportive care are essential.
Detailed clinical notes on muscle strength, range of motion, and any imaging studies performed.
Patients presenting with muscle pain and swelling, particularly after trauma or surgery.
Ensure to document the genetic basis of the condition and any family history of similar disorders.
Genetic test results, family history, and detailed patient history.
Patients with a family history of myositis ossificans or unexplained muscle ossification.
Documentation should include the specific mutation identified and its implications for treatment.
Used for assessing functional limitations in patients with myositis ossificans progressiva.
Detailed evaluation of muscle strength, range of motion, and functional limitations.
Rheumatology and physical therapy should collaborate on treatment plans.
Myositis ossificans progressiva is a rare genetic disorder characterized by the abnormal formation of bone in muscles and connective tissues, leading to progressive muscle weakness and mobility issues.
Diagnosis typically involves clinical evaluation, imaging studies to assess bone formation, and genetic testing for mutations in the ACVR1 gene.
Treatment focuses on managing symptoms, including pain relief and physical therapy to maintain mobility. There is currently no cure for the condition.
