Poisoning by antithyroid drugs, self-harm, sequela

This code signifies a long-term consequence or complication resulting from a deliberate overdose of antithyroid medications. It indicates that the patient intentionally self-harmed using these drugs, and the current encounter addresses a residual effect of that poisoning event, not the acute poisoning itself.

Apply this code when a patient presents with a chronic condition or persistent health issue directly attributable to a past, intentional self-poisoning with antithyroid drugs. This would include follow-up care for organ damage, endocrine dysfunction, or other lasting sequelae. Do not use for the initial acute poisoning episode.

• Always assign an additional code(s) to specify the nature of the sequela (e.g., specific organ damage, endocrine disorder).
• Ensure documentation clearly links the current condition to a past intentional antithyroid drug poisoning.
• This code is for the sequela, not the acute event; for the acute event, a different T38.2X2_ code would be used.
