Toxic effect of inorganic substances, accidental, sequela

This code describes the long-term or residual effects resulting from an accidental exposure to an inorganic substance not specifically classified elsewhere. These are conditions that persist after the acute phase of the poisoning has resolved, such as chronic organ damage or neurological deficits.

Apply this code when documenting a patient presenting with a current health problem that is a direct consequence of a past, unintentional toxic exposure to an inorganic substance. This is used for conditions like chronic kidney disease due to past heavy metal poisoning, or persistent neuropathy from a previous accidental chemical spill.

• Always sequence this code after the code(s) for the specific sequela being treated.
• Ensure the documentation clearly links the current condition to a past accidental toxic exposure to an inorganic substance.
• Do not use this code for acute toxic effects; refer to the acute poisoning codes for initial encounters.
