Posterior dislocation of left humerus, subsequent encounter

This code signifies a posterior displacement of the upper arm bone (humerus) from its normal position within the shoulder joint, specifically affecting the left side. It indicates that the patient is receiving follow-up care for this previously diagnosed injury, rather than the initial treatment.

Apply this code when documenting a patient's visit for ongoing management, rehabilitation, or evaluation of complications related to a prior posterior dislocation of the left humerus. This includes appointments for physical therapy, re-evaluation of healing, or assessment of chronic pain stemming from the initial injury.

• Ensure documentation clearly specifies "left" humerus and "posterior" dislocation.
• The "D" seventh character indicates subsequent care; do not use for initial treatment or sequela.
• Pair with appropriate external cause codes (e.g., W00-Y38) if the cause of the original injury is relevant to the subsequent encounter.
