Congenital unstable hip

This code describes a congenital condition where the hip joint is abnormally loose or dislocatable at birth. It signifies a developmental abnormality of the hip joint's stability, often due to shallow acetabulum or lax ligaments, making it prone to subluxation or dislocation.

Use this code for newborns or infants diagnosed with hip instability present at birth, often identified through physical examination maneuvers like Ortolani or Barlow tests. Documentation should clearly state "congenital unstable hip" or "developmental dysplasia of the hip (DDH) with instability."

• Distinguish from acquired hip instability or traumatic dislocations.
• Do not use for congenital hip dislocation (Q65.0-Q65.2) unless specifically documented as unstable without full dislocation.
• Consider laterality (left, right, bilateral) if specified in the documentation, using appropriate subcodes.
