Poisoning by thyroid hormones and sub, self-harm, subs

This code signifies a patient presenting for follow-up care related to an overdose of thyroid hormones or their synthetic substitutes, where the overdose was deliberately self-inflicted. This includes conditions like thyrotoxicosis or other adverse effects resulting from the intentional ingestion of these medications.

Apply this code when documenting subsequent encounters for patients who have previously been treated for an intentional overdose of thyroid medications. This would include office visits, hospital readmissions, or other follow-up care related to the initial self-harm event. It is crucial to use this code for ongoing management and monitoring of the patient's recovery and any lingering effects.

• Always sequence this code after the primary diagnosis for the specific manifestation of the poisoning (e.g., thyrotoxicosis).
• Ensure documentation clearly states the intentional nature of the self-harm and that this is a subsequent encounter.
• Do not use this code for initial encounters; a different seventh character would be appropriate for the initial treatment phase.
