Toxic effect of herbicides and fungicides, self-harm, init

This code signifies a patient presenting with adverse health effects resulting from the deliberate ingestion, inhalation, or other exposure to herbicides or fungicides, with the intent to cause self-harm. The toxic effects can range from mild irritation to severe systemic poisoning, impacting various organ systems.

Apply this code when documentation clearly indicates a patient has intentionally poisoned themselves with a herbicide or fungicide, and this is the initial encounter for this specific episode of care. This includes emergency department visits, initial hospital admissions, or the first outpatient visit related to the self-harm attempt.

• Always sequence this code first when it represents the primary reason for the encounter, followed by codes for specific toxic manifestations.
• Ensure documentation explicitly states "intentional self-harm" or similar phrasing to support the fifth character "2".
• Confirm this is the "initial encounter" (seventh character "A") for the poisoning event; subsequent encounters would use "D" or "S".
