Poisoning by local astringents/detergents, self-harm, subs

This code signifies a patient presenting for follow-up care related to a self-inflicted poisoning from substances like witch hazel, calamine lotion, or certain cleaning detergents. The initial act of intentional self-harm has already occurred, and the patient is now receiving ongoing treatment or monitoring for the effects of the exposure.

Apply this code when documenting subsequent encounters for patients who intentionally ingested or otherwise exposed themselves to local astringents or detergents with the intent to cause self-harm. This includes follow-up appointments for organ damage assessment, psychiatric evaluation, or ongoing management of symptoms resulting from the poisoning.

• Ensure documentation clearly states "intentional self-harm" and specifies the substance as a local astringent or detergent.
• Confirm this is a subsequent encounter; for the initial encounter, a different 7th character would be used.
• Always sequence this code after any codes for specific manifestations or injuries resulting from the poisoning.
