Unsp injury of intercostal blood vessels, left side, subs

This code signifies an injury to the blood vessels located between the ribs on the left side of the body, where the specific type of vessel (artery or vein) is not documented. It indicates that the patient is receiving follow-up care for this injury after the initial treatment phase.

Use this code for a patient presenting for ongoing management, such as wound care, pain management, or monitoring for complications, related to a previously diagnosed but unspecified intercostal blood vessel injury on the left. This applies when the initial injury has already been treated and the patient is no longer in the acute phase of care.

• Ensure documentation clearly states "left side" and that the encounter is for subsequent care.
• Only use this code when the specific intercostal vessel (artery or vein) is not identified in the medical record.
• Pair with external cause codes (V, W, X, Y categories) to describe the circumstances of the injury, if known.
