Poisoning by propionic acid derivatives, assault, init

This code signifies a deliberate act of harm involving poisoning by propionic acid derivatives, such as ibuprofen or naproxen, where the patient is the victim of an assault. The "initial encounter" indicates that this is the first time the patient is receiving active treatment for this specific poisoning event.

Apply this code when documentation clearly states that a patient has been poisoned by a propionic acid derivative due to an intentional act of assault by another party. This would be used for the initial hospital visit, emergency department encounter, or first outpatient visit for treatment of the acute effects of the poisoning.

• Always sequence this code after the primary injury or condition resulting from the poisoning, if applicable.
• Ensure documentation explicitly states "assault" and identifies the substance as a propionic acid derivative.
• Do not use for accidental ingestions, self-harm, or adverse effects of therapeutic use.
