Contusion of lung, bilateral, subsequent encounter

This code signifies bruising of both lungs, often resulting from blunt force trauma to the chest. A lung contusion involves hemorrhage and edema within the lung parenchyma without a major laceration, impairing gas exchange.

Apply this code when documenting a patient's follow-up care for a previously diagnosed bilateral lung contusion. This includes subsequent hospital visits, outpatient clinic appointments, or rehabilitation sessions related to the ongoing management or recovery from the injury.

• Ensure documentation clearly states "bilateral" involvement of the lungs.
• Confirm the encounter is for follow-up care, not the initial injury.
• Always sequence this code after the primary injury code, if applicable, or as the primary diagnosis if the contusion is the sole reason for the encounter.
