Oth injury of intercostal blood vessels, unsp side, sequela

This code signifies a long-term complication or late effect resulting from a previously sustained injury to intercostal blood vessels, where the specific type of injury is known but not further detailed (e.g., laceration, contusion) and the affected side is not documented. It indicates that the initial acute injury has resolved, but residual issues related to the vascular damage persist.

Use this code when documenting a sequela of an intercostal blood vessel injury that occurred in the past, and the patient is now presenting with a chronic condition directly attributable to that old injury. This applies when the specific vessel involved is not precisely identified beyond "intercostal" and the laterality was not specified in the original injury documentation or is no longer relevant to the sequela. Examples include chronic pain, scarring, or functional impairment stemming from the prior vascular trauma.

• Always sequence this sequela code after the code for the specific nature of the sequela (e.g., chronic pain, scar).
• Ensure documentation clearly links the current condition to a past intercostal blood vessel injury.
• Avoid using this code for acute or current injuries; it is exclusively for late effects.
