Posterior subluxation of left humerus, initial encounter

This code signifies a partial dislocation of the left shoulder joint where the head of the humerus has moved backward relative to the glenoid cavity, but remains in contact. This injury often results in pain, limited range of motion, and instability of the shoulder.

Apply this code for patients presenting with a newly diagnosed posterior subluxation of the left humerus, such as after a fall onto an outstretched arm or a direct blow to the front of the shoulder. It is appropriate for the initial treatment and evaluation of this specific shoulder injury.

• Ensure documentation clearly specifies "posterior" and "subluxation" for the left humerus.
• Verify this is the initial encounter for this specific injury; subsequent care would use a different seventh character.
• Do not use for complete dislocations or anterior/inferior subluxations.
