Laceration of lung, unilateral, subsequent encounter

This code signifies a tear or cut in one lung that is being treated after the initial encounter. It indicates that the patient is receiving follow-up care for a previously diagnosed unilateral lung laceration, such as wound care, monitoring for complications, or rehabilitation.

Apply this code when documenting care for a patient who has already been seen for an acute unilateral lung laceration and is now presenting for subsequent treatment. This includes visits for ongoing management, evaluation of healing, or addressing delayed complications related to the initial injury.

• Ensure documentation clearly states "subsequent encounter" or similar language indicating ongoing care.
• Verify the laceration is unilateral; bilateral involvement would require a different code.
• Always code the underlying cause of the laceration (e.g., trauma code) in addition to this injury code.
