Poisoning by sulfonamides, intentional self-harm, init

This code signifies a patient presenting with adverse effects resulting from the deliberate ingestion or administration of sulfonamide medications with the intent to cause self-harm. The patient is in the initial phase of treatment for this poisoning event.

Apply this code when documentation clearly indicates a sulfonamide overdose was intentionally self-inflicted, such as in suicide attempts or gestures. This code is appropriate for the first encounter where the poisoning is diagnosed and treatment is initiated.

• Always sequence this code first, followed by codes for specific manifestations of the poisoning.
• Requires clear documentation of "intentional self-harm" and "initial encounter."
• Do not use for accidental poisoning or adverse effects from therapeutic use.
