Posterior subluxation of left hip, initial encounter

This diagnosis code signifies a partial dislocation of the left hip joint where the femoral head has shifted backward relative to the acetabulum. It indicates that the patient is receiving active treatment for this specific injury, such as reduction, immobilization, or initial surgical repair.

Use this code for patients presenting with a newly diagnosed posterior subluxation of the left hip. This applies to the initial visit for the injury, as well as any subsequent visits where active treatment for the subluxation is being rendered.

• Ensure documentation clearly specifies "posterior" and "left" hip to support this code.
• Verify the encounter is indeed the "initial encounter" for this specific injury; subsequent care would require a different seventh character.
• Distinguish subluxation (partial dislocation) from complete dislocation, which has a separate code.
