Penetrating wound with foreign body of left eyeball, sequela

This code signifies a chronic or late effect of a penetrating injury to the left eyeball where a foreign body remains embedded. This condition implies that the initial acute injury has resolved, but ongoing issues or complications stemming from the retained foreign object persist. Such sequelae can include chronic inflammation, vision impairment, or other long-term ocular damage.

Apply this code when documentation clearly indicates a past penetrating injury to the left eye with a retained foreign body, and the patient is presenting for treatment of a complication or residual effect directly attributable to that foreign body. This is appropriate for follow-up care or when the long-term consequences of the injury are being addressed, rather than the acute injury itself. Documentation should specify the laterality (left eye) and the presence of a foreign body as the cause of the sequela.

• Ensure documentation explicitly states "sequela" or describes a chronic condition resulting from a past penetrating injury with a foreign body.
• Do not use for acute penetrating injuries; those require codes from the initial encounter or subsequent encounter categories.
• Always sequence this code after the primary diagnosis describing the specific sequela (e.g., chronic uveitis due to retained foreign body).
