Unsp injury of intercostal blood vessels, unsp side, sequela

This code signifies a long-term consequence or complication stemming from an injury to the blood vessels located between the ribs. The specific type of intercostal vessel (artery or vein) and the side of the body affected are not documented or are unknown.

Apply this code when a patient presents with a current condition or symptom that is a direct result of a past, unspecified injury to intercostal blood vessels. This is appropriate for follow-up encounters addressing residual effects years after the initial trauma.

• Only use this code for sequelae (late effects) of an injury, not for the initial acute injury.
• Avoid this code if the specific intercostal vessel (artery or vein) or the side of the body is known and documented.
• Always sequence this code after the code for the specific sequela being treated.
