Toxic effect of thallium, intentional self-harm, sequela

This code signifies the long-term or residual effects resulting from a deliberate act of self-poisoning with thallium. These sequelae can manifest as chronic neurological damage, gastrointestinal issues, or other persistent health problems that arose directly from the initial toxic exposure. The patient is no longer in the acute phase of poisoning but is experiencing lasting complications.

Use this code for patients presenting with chronic conditions or permanent damage directly attributable to a past intentional thallium overdose. This applies when the acute poisoning event has concluded, and the focus of care is on managing the enduring consequences. Examples include ongoing neuropathy, alopecia, or cognitive deficits linked to the prior self-harm attempt.

• Always sequence this code after the code for the specific sequela being treated (e.g., G62.0 for drug-induced polyneuropathy).
• Ensure documentation clearly links the current condition to a past intentional thallium exposure.
• Do not use this code for acute thallium poisoning; instead, use the appropriate acute poisoning code.
