Anterior subluxation of left humerus, initial encounter

This diagnosis code signifies a partial dislocation of the left shoulder joint where the head of the humerus has moved forward out of the glenoid cavity, but still maintains some contact. It specifically identifies the initial presentation or treatment for this injury.

Apply this code for patients presenting with a newly diagnosed anterior subluxation of their left shoulder. This is appropriate for the first time a patient receives medical attention for this specific injury, including emergency department visits or initial clinic appointments.

• Ensure documentation specifies "anterior" and "left" to support this code.
• Verify the encounter is indeed the "initial" one for this injury; subsequent encounters will use a different seventh character.
• Distinguish from a complete dislocation (luxation) where there is no contact between the humeral head and glenoid.
