Unspecified injury of lung, unilateral, subsequent encounter

This code signifies a follow-up encounter for an unspecific injury to a single lung. It indicates that the specific nature of the lung damage (e.g., contusion, laceration) is not documented, or the injury type is unknown, and the injury affects only one side of the chest.

Use this code for subsequent visits where a patient is being monitored or treated for a previously diagnosed, but unspecified, unilateral lung injury. This applies when the initial injury was not clearly defined, or further diagnostic details are still pending.

• Ensure documentation clearly states "unspecified" and "unilateral" for the lung injury.
• The "D" seventh character indicates a subsequent encounter, meaning the patient is receiving routine care during the healing or recovery phase.
• Avoid using this code if a more specific diagnosis (e.g., lung contusion, pneumothorax) is available in the medical record.
