Poisoning by thyroid hormones and substitutes, assault, subs

This code signifies a patient presenting with adverse effects from thyroid hormone medication, such as levothyroxine, due to an intentional act of harm by another person. The "subsequent encounter" indicates that the patient is receiving follow-up care for the poisoning after initial treatment.

Use this code when documenting ongoing management or evaluation of a patient who was intentionally poisoned with thyroid hormones by another individual. This applies to visits following the initial emergency treatment, such as outpatient follow-up appointments or subsequent hospital admissions for complications.

• Ensure documentation clearly states the poisoning was an assault and not accidental or self-inflicted.
• Verify this is a "subsequent encounter" and not the initial treatment for the poisoning.
• Always sequence this code after the primary diagnosis indicating the specific effects or complications of the poisoning.
