Poisoning by opth drugs and preparations, self-harm, init

This code signifies a patient presenting with adverse effects from intentionally self-administering ophthalmological medications or preparations with suicidal intent. The patient is in the initial phase of treatment for this poisoning.

Apply this code when documentation clearly indicates a patient has ingested, injected, or otherwise introduced eye-related drugs (e.g., eye drops, ointments) into their system with the express purpose of self-harm. This is appropriate for the first encounter where the poisoning is evaluated and treated.

• Ensure "intentional self-harm" is explicitly documented, not accidental or therapeutic misadventure.
• Verify the substance involved is an ophthalmological drug or preparation.
• Confirm this is the initial encounter for the poisoning event; subsequent care would use a different encounter character.
