Arthrogryposis multiplex congenita
ICD-10 Q74.3 is a billable code used to indicate a diagnosis of arthrogryposis multiplex congenita.
Arthrogryposis multiplex congenita (AMC) is a rare congenital disorder characterized by multiple joint contractures affecting the limbs and sometimes the spine. The condition arises from a variety of underlying causes, including genetic factors, environmental influences, and maternal conditions during pregnancy. AMC is often associated with reduced fetal movement, leading to the characteristic deformities. Clinically, patients may present with flexion or extension deformities of the joints, muscle weakness, and in some cases, associated anomalies such as scoliosis, clubfoot, or limb reduction defects. The severity of the condition can vary widely, with some individuals experiencing significant functional limitations while others may have mild manifestations. Diagnosis is typically made through clinical examination and may be supported by imaging studies. Genetic testing can help identify specific syndromes associated with AMC, which can guide management and prognosis. Early intervention, including physical therapy and orthopedic surgery, is crucial for improving mobility and function in affected individuals.
Documentation should include detailed descriptions of joint involvement, functional limitations, and any associated conditions. Growth and developmental milestones should also be documented.
Pediatric patients presenting with joint stiffness, difficulty in movement, or developmental delays requiring physical therapy or orthopedic intervention.
Coders should ensure that all associated congenital anomalies are documented to avoid undercoding or misclassification.
Genetic documentation should include results from genetic testing, family history, and any syndromic associations with AMC.
Patients undergoing genetic counseling for AMC, including discussions about inheritance patterns and recurrence risks.
Consideration of syndromic associations is crucial for accurate coding and understanding the broader implications of the diagnosis.
Used in conjunction with AMC management to improve joint mobility and strength.
Documentation should include the specific exercises performed and the patient's response.
Pediatric physical therapy notes should detail the child's progress and any modifications to the treatment plan.
The primary cause of AMC is often multifactorial, involving genetic predispositions, environmental factors, and maternal conditions that lead to reduced fetal movement. Specific genetic syndromes may also be associated with AMC, necessitating genetic evaluation.
