Poisn by succinimides and oxazolidinediones, self-harm, init

This code signifies a patient presenting with adverse effects resulting from the deliberate self-administration of succinimide or oxazolidinedione medications. These drug classes are primarily anticonvulsants, and the poisoning is a consequence of an intentional act to cause harm to oneself.

Apply this code when documentation clearly indicates a patient has intentionally overdosed on or misused a succinimide (e.g., ethosuximide) or oxazolidinedione (e.g., trimethadione) and is receiving initial treatment for the resulting toxic effects. This is appropriate for emergency department visits, initial hospital admissions, or the first encounter with a healthcare provider for this specific poisoning event.

• Always confirm the intent was self-harm, not accidental or assault.
• Ensure the specific drug class (succinimide or oxazolidinedione) is documented.
• The "A" in the 7th character indicates this is the initial encounter for treatment of the poisoning.
