Poisoning by otorhino drugs and preparations, assault, subs

This code signifies a poisoning event resulting from the intentional administration of drugs or preparations primarily used for ear, nose, and throat conditions, where the intent was to harm the patient. It specifically indicates that this is not the initial encounter for this poisoning, but rather a follow-up visit for ongoing care, monitoring, or treatment of the sequelae.

Use this code for subsequent encounters when a patient is receiving follow-up care for poisoning by otorhinolaryngological medications that was inflicted by another person with malicious intent. This includes visits for managing complications, monitoring recovery, or adjusting treatment plans after the initial acute phase of the assault.

• Always assign an additional code for the specific drug or substance involved, if known, from categories T36-T50.
• Ensure documentation clearly supports the "assault" intent and that the encounter is not the initial treatment for the poisoning.
• Do not use this code for accidental poisonings, self-harm, or undetermined intent; specific codes exist for those scenarios.
