Posterior subluxation of unspecified hip, initial encounter

This code signifies a partial dislocation of the hip joint where the femoral head has slipped backward out of the acetabulum, but the joint surfaces are still in partial contact. It indicates that the patient is receiving active treatment for this specific injury for the first time.

Use this code for patients presenting with a newly diagnosed posterior subluxation of the hip, regardless of the specific hip (left or right) involved. This applies to initial evaluations, surgical repairs, or other primary treatments for the injury.

• Ensure documentation clearly specifies "posterior subluxation" and not a full dislocation.
• Only use the "A" seventh character for the initial encounter for active treatment of the injury.
• If the laterality (left or right hip) is known, a more specific code should be used.
