Poisoning by iron and its compounds, self-harm, subs

This code signifies a patient presenting for follow-up care or treatment of complications arising from an intentional overdose of iron or iron-containing compounds. The initial self-harm event has already occurred, and this encounter addresses ongoing management or sequelae.

Apply this code when a patient is seen for continued treatment of iron poisoning that was self-inflicted, such as for monitoring liver function, chelation therapy, or managing gastrointestinal damage, after the initial acute presentation. It is used for subsequent visits related to the same poisoning episode.

• Ensure documentation clearly states the poisoning was intentional self-harm and this is not the initial encounter.
• Always sequence this code after any codes for the specific manifestations or complications of the iron poisoning.
• Do not use for accidental poisonings or initial acute care encounters.
