Unspecified injury of lung, bilateral, sequela

This code signifies a long-term effect or complication arising from an unspecified injury to both lungs. It indicates that the original lung injury, which affected both sides, has resolved but has left behind a lasting health problem. The specific nature of the original injury is not documented or is unknown.

This code is appropriate for documenting a current condition that is a direct consequence of a past, bilateral, and unspecified lung injury. This would be used when the acute phase of the injury has passed, and the patient is now being treated for a residual effect, such as chronic respiratory issues or scarring, where the original injury type isn't specified.

• Always assign a secondary code for the specific sequela (e.g., chronic respiratory failure, pulmonary fibrosis) if known.
• Ensure documentation clearly links the current condition to a past bilateral lung injury.
• Avoid using this code for acute injuries; it is exclusively for sequelae.
