Congenital malformation of knee

This code represents a birth defect affecting the structural development of the knee joint, excluding conditions primarily characterized by dislocation or hyperextension. It encompasses a range of anomalies present at birth that result in an abnormal formation of the knee's bones, ligaments, or other soft tissues. These malformations can impact joint stability, range of motion, and overall function.

Use this code when documentation specifies a congenital structural abnormality of the knee, such as hypoplasia or aplasia of knee components, or other specified malformations not otherwise classified. This code is appropriate when the physician explicitly diagnoses a congenital malformation of the knee, supported by imaging studies or clinical examination findings.

• Differentiate from acquired knee conditions; this code is strictly for congenital defects.
• Carefully review documentation to ensure the condition is not better described by the Excludes1 notes, particularly congenital dislocation or genu recurvatum.
• Consider additional codes for any associated functional impairments or secondary conditions resulting from the malformation.
