Myositis ossificans progressiva, unspecified forearm
ICD-10 M61.139 is a billable code used to indicate a diagnosis of myositis ossificans progressiva, unspecified forearm.
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 begins in early childhood and progresses over time, leading to significant muscle weakness and restricted mobility. In the case of unspecified forearm involvement, the ossification occurs in the muscles of the forearm, which can severely limit the range of motion and functionality of the arm. Patients may experience episodes of swelling, pain, and stiffness in the affected areas, often exacerbated by trauma or injury. The ossification process is gradual and can lead to the formation of heterotopic bone, which is bone that develops in an abnormal location. Diagnosis is primarily clinical, supported by imaging studies such as X-rays or MRI to visualize the ossified areas. Management focuses on symptomatic relief, physical therapy, and avoiding activities that may trigger 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 imaging results.
Patients presenting with unexplained muscle pain and swelling, particularly after trauma.
Rheumatologists should be aware of the genetic basis of MOP and consider genetic counseling for affected families.
Surgical notes if intervention is performed, including pre-operative assessments.
Patients requiring surgical intervention for severe ossification affecting mobility.
Orthopedic surgeons must document the extent of ossification and its impact on function.
Used for follow-up visits for patients with myositis ossificans progressiva.
Document history, examination findings, and treatment plan.
Rheumatologists should ensure comprehensive documentation of symptoms and treatment response.
Common symptoms include swelling, pain, stiffness in the affected muscles, and progressive loss of mobility. Symptoms often worsen after trauma.
