Flexion deformity, left ankle and toes

This diagnosis code signifies an abnormal and persistent bending or contracture of the left ankle and/or toes, where the joint is fixed in a flexed position. This deformity restricts the normal range of motion and can lead to functional impairment and pain in the affected foot.

Apply this code when documentation explicitly states a flexion deformity affecting the left ankle and/or toes. This is commonly seen in conditions such as cerebral palsy, stroke sequelae, nerve damage, or severe arthritis leading to joint contracture. Supporting documentation should include physical exam findings detailing the fixed flexion, limited range of motion, and laterality.

• Ensure documentation specifies "flexion" deformity; other deformities (e.g., extension, valgus, varus) have different codes.
• Verify the laterality is clearly documented as "left" to avoid coding errors.
• Do not use this code for transient or voluntary flexion; it must represent a fixed, pathological deformity.
