Myositis ossificans progressiva, right foot
ICD-10 M61.174 is a billable code used to indicate a diagnosis of myositis ossificans progressiva, right foot.
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 M61.174, the ossification specifically affects the right foot, leading to significant functional impairment. Patients may experience episodes of swelling and pain in the affected area, which can be mistaken for other inflammatory conditions. The ossification process can severely restrict mobility and lead to complications such as joint deformities. Diagnosis is primarily clinical, supported by imaging studies that reveal calcification in soft tissues. Genetic testing may confirm the diagnosis by identifying mutations in the ACVR1 gene, which is responsible for the condition. Management focuses on symptomatic relief, physical therapy, and avoiding trauma to the affected area, as injury can exacerbate ossification. Surgical intervention is rarely indicated and is approached with caution due to the risk of further ossification.
Detailed clinical notes on symptoms, physical examination findings, and imaging results.
Patients presenting with muscle stiffness and pain, particularly after trauma.
Consideration of genetic counseling and testing for family members.
Surgical notes if intervention is performed, imaging studies, and rehabilitation plans.
Patients requiring surgical evaluation for joint stiffness or deformity.
Careful assessment of the risks of surgery due to potential for further ossification.
Used for assessing functional limitations due to myositis ossificans.
Detailed evaluation of muscle strength and range of motion.
Rheumatology may require specific assessments related to inflammatory conditions.
