Poisoning by thyroid hormones and substitutes, assault, init

This code signifies an adverse health event resulting from the intentional administration of thyroid hormones or their synthetic substitutes by another person, with the intent to cause harm. The patient is experiencing the initial effects or treatment for this poisoning.

Apply this code when a patient presents with symptoms of thyroid hormone toxicity (e.g., hyperthyroidism, cardiac arrhythmias) due to an overdose or inappropriate administration by another individual. This is used for the initial encounter where the poisoning is first evaluated and treated.

• Ensure documentation clearly states the poisoning was due to an "assault" and not accidental or self-inflicted.
• Always sequence this code first as the primary diagnosis when it is the reason for the encounter.
• Remember to also code any specific symptoms or manifestations of the poisoning.
