Toxic effect of gadolinium, self-harm, initial encounter

This code signifies a patient presenting with adverse health effects resulting from the deliberate ingestion or administration of gadolinium, with the intent to cause self-harm. The toxic reaction is acute and is being addressed for the first time.

Apply this code when documenting a patient who has intentionally poisoned themselves with gadolinium, such as in a suicide attempt, and is receiving initial treatment for the resulting toxicity. This would include scenarios like acute renal failure or neurological symptoms directly attributable to the gadolinium overdose.

• Ensure documentation clearly states "intentional self-harm" and specifies gadolinium as the toxic agent.
• Confirm this is the patient's first encounter for this specific poisoning event.
• Code any specific manifestations of the toxicity (e.g., acute kidney injury) as additional diagnoses.
