Penetrating wound w/o foreign body of left eyeball, subs

This code signifies a penetrating injury to the left eyeball where no foreign object remains embedded within the eye. This injury involves a full-thickness breach of the globe, such as from a sharp object, but the causative agent is no longer present. The "subsequent encounter" indicates that the patient is receiving follow-up care for this previously diagnosed injury.

Use this code for follow-up visits, medication management, wound care, or monitoring of complications related to a penetrating left eyeball wound that has already been initially treated and where no foreign body was retained. Documentation should clearly state a penetrating injury to the left eye, confirm the absence of a foreign body, and indicate that the encounter is not for the initial acute treatment.

• Ensure documentation explicitly states "left" eyeball and confirms the absence of a foreign body.
• Distinguish carefully from initial encounters (use A or D suffix) or cases where a foreign body is present (different code series).
• Always sequence this code after any acute complications or conditions being treated during the subsequent encounter.
