Congenital partial dislocation of left hip, unilateral

This code signifies a birth defect where the left hip joint is not fully dislocated but is partially displaced from its normal position. This condition is present at birth and affects only one hip. It represents a less severe form of developmental dysplasia of the hip (DDH) compared to a complete dislocation.

Use this code when documentation explicitly states a congenital partial dislocation or subluxation of the left hip. This diagnosis is typically made in infants or young children based on physical examination findings (e.g., limited abduction, asymmetry of skin folds) and confirmed by imaging studies such as ultrasound or X-ray.

• Differentiate carefully between partial (subluxation) and complete dislocation; a different code exists for complete dislocation.
• Ensure the documentation specifies "left" hip and "unilateral" to accurately assign this code.
• Do not use this code for acquired hip dislocations or for bilateral involvement.
