Poisn by oth agents prim acting on the resp sys, asslt, init

This code signifies a patient presenting with adverse effects from an intentional, harmful exposure to a substance that primarily targets the respiratory system, excluding gases, fumes, or vapors. The poisoning is the result of an assault, meaning it was inflicted by another person with malicious intent. This code is used for the initial phase of treatment for this specific type of poisoning.

This code is appropriate when a patient is admitted or seen for the first time due to respiratory distress or other symptoms caused by a substance (e.g., certain pesticides, chemical agents) administered by another individual with the intent to harm. Examples include a patient poisoned by a liquid chemical poured on them that causes respiratory symptoms, or a substance ingested under duress that primarily affects breathing. It is used during the acute phase of care for this event.

• Always assign an additional code for the specific substance if known (e.g., from categories T51-T65).
• Remember to use an external cause code (Y90-Y99) to further describe the circumstances of the assault.
• This "A" initial encounter suffix is only used for the first time the patient is seen for this specific poisoning event.
