Other injuries of lung, unilateral, sequela

This code signifies a long-term or residual effect stemming from a past injury to a single lung, excluding contusions, lacerations, or punctures. These sequelae can include chronic pain, reduced lung function, or other persistent complications directly attributable to the original trauma.

Apply this code when documenting the lasting impact of a previous, non-specific lung injury on one side of the chest. This is appropriate for follow-up visits where the patient is being treated for the chronic consequences, rather than the acute injury itself.

• Always assign this code as a secondary diagnosis, following the code for the specific sequela (e.g., chronic respiratory failure).
• Ensure documentation clearly links the current condition to a prior lung injury and specifies laterality.
• Do not use for acute injuries; this code is exclusively for the late effects or complications.
