Poisoning by sulfonamides, assault, initial encounter

This code signifies a case where a patient has been poisoned by a sulfonamide medication, and the poisoning was intentionally inflicted by another person. The "initial encounter" designation indicates that this is the first time the patient is receiving active treatment for this specific poisoning.

Apply this code when documentation clearly states sulfonamide toxicity resulting from an assault, such as a forced administration or intentional overdose by another party. This code is appropriate for the initial hospital visit, emergency department encounter, or first outpatient visit for treatment of the acute poisoning.

• Always confirm the intent of the poisoning (assault) and the specific substance (sulfonamide).
• Ensure "initial encounter" is appropriate; subsequent care for the same poisoning would use a different encounter character.
• Code any associated signs, symptoms, or adverse effects of the poisoning in addition to this code.
