Myositis ossificans progressiva, upper arm
ICD-10 M61.12 is a billable code used to indicate a diagnosis of myositis ossificans progressiva, upper arm.
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 M61.12, the focus is specifically on the upper arm, where ossification can lead to stiffness and pain, severely impacting the patient's ability to 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 and inflammation in the affected muscles, followed by the gradual development of bone tissue. Diagnosis is often confirmed through imaging studies such as X-rays or MRI, which reveal the presence of heterotopic ossification. Management of MOP is primarily supportive, focusing on physical therapy to maintain mobility and prevent contractures, as surgical intervention is often complicated by the risk of further ossification.
Detailed clinical notes on symptoms, physical examination findings, and treatment plans.
Patients presenting with muscle pain and swelling, particularly in the upper arm, with a family history of similar conditions.
Documentation should include genetic testing results and imaging studies to support the diagnosis.
Surgical notes if intervention is performed, along with pre-operative and post-operative assessments.
Patients requiring surgical intervention for severe contractures or functional impairment.
Careful documentation of the risks associated with surgery due to the nature of the condition.
Used for rehabilitation of muscle strength in patients with MOP.
Documentation of the patient's progress and specific exercises performed.
Physical therapy notes should detail the patient's response to therapy.
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.
