Unsp injury of unspecified blood vessel of thorax, sequela

This code signifies a long-term or late effect of an unspecified injury to an unspecified blood vessel within the thoracic cavity. It indicates that the initial injury has resolved, but the patient continues to experience residual symptoms or complications directly attributable to that past vascular trauma.

Use this code when documenting a current condition that is a sequela of a previous, unspecified injury to a thoracic blood vessel, and the specific vessel or nature of the injury is not documented. This applies to follow-up encounters for chronic issues stemming from such an injury, after the acute phase has passed.

• Always sequence this code after the code for the specific sequela or current condition being treated.
• Ensure documentation clearly links the current condition to a past, unspecified thoracic blood vessel injury.
• If the specific blood vessel or nature of the injury is known, a more specific sequela code should be used.
