Unsp injury of unspecified pulmonary blood vessels, sequela

This code signifies a long-term or late-effect complication resulting from an injury to an unspecified blood vessel within the lungs. It indicates that the specific type of injury (e.g., laceration, contusion) and the precise pulmonary vessel involved are not documented.

This code is appropriate when a patient presents with a current condition or symptom that is a direct consequence of a past, unspecifed injury to a pulmonary blood vessel. It should be used when the original injury has healed, but its lasting effects are still being treated or monitored, and no further detail about the initial injury or vessel is available.

• Always sequence this code after the code(s) for the specific sequela being treated.
• Avoid using this code if the acute injury is still being actively treated; instead, use an acute injury code.
• Query the provider for more specific details regarding the type of injury and the specific pulmonary vessel if possible, to allow for a more precise code.
