Unspecified injury of pleura, subsequent encounter

This code signifies an unspecified injury to the pleura, the membrane lining the lungs and chest cavity, that is being treated or evaluated following the initial encounter. It indicates a lack of specific detail regarding the nature of the pleural injury itself, such as a tear, contusion, or other trauma. This code is used when the patient is seen for follow-up care related to the injury.

Use this code for subsequent encounters when a patient presents for follow-up, monitoring, or continued treatment of a previously diagnosed, but unspecified, pleural injury. This applies when the initial injury has already been coded with an initial encounter (A) or subsequent encounter (D) code, and the current visit is for ongoing management. It is appropriate when the specific type of pleural injury remains undiagnosed or is not documented with greater specificity.

• Ensure the encounter is truly "subsequent" and not an initial presentation for the injury.
• Always attempt to query for a more specific diagnosis of the pleural injury if possible.
• Pair with an external cause code to describe the circumstances of the injury.
