Poisoning by opth drugs and preparations, assault, subs

This code signifies a poisoning event resulting from the intentional administration of ophthalmological medications or preparations by another person, occurring during a follow-up visit for the management of the poisoning. It indicates that the patient is receiving ongoing care for the adverse effects of the assault.

Use this code when documenting subsequent encounters for a patient who was intentionally poisoned with eye drops or other ophthalmic substances by another individual. This applies to follow-up appointments, medication adjustments, or monitoring for long-term complications related to the initial assault.

• Ensure documentation clearly states the poisoning was an assault and not accidental or self-inflicted.
• Confirm this is a subsequent encounter; initial treatment would use a different encounter character.
• Always code with an external cause code (e.g., X92.XXXA) to fully describe the circumstances of the assault.
