Contusion of lung, unspecified, initial encounter

This code signifies a bruise to the lung tissue, without further specification of which lung or the exact nature of the contusion. It indicates damage to the lung parenchyma, often resulting from blunt force trauma to the chest. This injury can impair gas exchange and lead to respiratory distress.

Apply this code for a patient presenting with an unconfirmed or generalized lung contusion following a traumatic event, such as a motor vehicle accident or a fall. It is appropriate when the medical record does not specify laterality (left or right lung) or the specific lobe affected. This code is used for the initial treatment of the injury.

• Only use this code when laterality and specific lung lobe are not documented.
• Ensure the "A" for initial encounter is appended for the first time the patient is seen for this injury.
• Code any associated external causes of injury and other traumatic findings.
