Toxic effect of arsenic and its compounds, self-harm, subs

This code signifies a patient presenting for follow-up care or treatment of adverse health effects resulting from intentionally self-inflicted poisoning by arsenic or its compounds. It indicates that the initial acute phase of treatment for the toxic exposure has concluded, and the patient is now receiving ongoing management for residual symptoms or complications.

Use this code for subsequent encounters related to the toxic effects of arsenic, such as follow-up appointments for organ damage assessment, neurological sequelae, or ongoing chelation therapy after an intentional self-harm attempt. This applies when the patient is no longer in the initial acute treatment phase but requires continued medical attention for the poisoning's aftermath.

• Ensure documentation clearly specifies "intentional self-harm" as the intent of the arsenic exposure.
• Verify this is a "subsequent encounter" and not the initial treatment for the acute poisoning.
• Code any specific manifestations of arsenic toxicity (e.g., polyneuropathy, renal failure) in addition to this code.
