Poisn by crbnc-anhydr inhibtr,benzo/oth diuretc,slf-hrm,subs

This code signifies a poisoning event resulting from the deliberate self-administration of carbonic-anhydrase inhibitors, benzothiadiazides, or other diuretic medications. The patient has intentionally harmed themselves with these substances, and this code is used for encounters following the initial treatment of the acute poisoning.

This code is appropriate for follow-up visits, such as psychiatric evaluations, therapy sessions, or medical appointments addressing ongoing effects or complications from a previous intentional overdose of diuretics. It should be used when the patient is no longer in the acute phase of poisoning but is receiving care related to the self-harm event.

• Ensure documentation clearly states "intentional self-harm" and specifies a diuretic medication as the causative agent.
• This "D" seventh character indicates a subsequent encounter; use "A" for initial encounters and "S" for sequela.
• Always code an underlying mental health condition (e.g., depression, anxiety) as a primary diagnosis when applicable, especially for intentional self-harm cases.
