Inferior subluxation of left humerus, initial encounter

This code signifies a partial dislocation of the left shoulder joint where the humeral head has moved downwards relative to the glenoid cavity. This condition indicates an incomplete separation of the joint surfaces, often resulting in pain and limited range of motion.

Apply this code for patients presenting with an initial episode of an inferior subluxation of the left humerus, such as following a fall or direct trauma to the shoulder. It is appropriate for the first time a patient is seen for this specific injury.

• Ensure documentation specifies "inferior" and "left" to support this code.
• The "A" seventh character indicates an initial encounter for active treatment of the injury.
• Distinguish from complete dislocations (S43.00-S43.02-) and other types of subluxations.
