Poisoning by opth drugs and preparations, assault, sequela

This code indicates a long-term health condition or complication resulting from a past intentional poisoning by ophthalmological drugs or preparations, inflicted by another person. The patient is experiencing persistent effects directly attributable to this assaultive event.

Use this code when documenting a sequela (e.g., chronic vision impairment, permanent eye damage, neurological deficits) that is a direct consequence of a previous assault involving ophthalmological medications. This code is appropriate for follow-up encounters long after the acute poisoning event has resolved, but its lasting effects persist.

• Always sequence this code after the code(s) for the specific sequela being treated (e.g., H53.41 for generalized visual field defect).
• Ensure documentation clearly links the current condition to the past assaultive poisoning by ophthalmological drugs.
• Do not use this code for the initial acute poisoning event; use the acute poisoning code with the appropriate seventh character for initial encounter.
