Toxic effect of ketones, intentional self-harm, init encntr

This code signifies a patient presenting with adverse health effects resulting from the deliberate ingestion or exposure to ketones, with the intent to cause self-harm. The patient is in the initial phase of treatment for this toxic exposure.

Apply this code when documenting an emergency department visit or initial inpatient admission for a patient who has intentionally poisoned themselves with ketones. This includes cases where the patient explicitly states self-harm intent or when clinical evidence strongly suggests it.

• Always assign an additional code for the specific manifestation of the toxic effect (e.g., metabolic acidosis).
• Ensure documentation clearly supports the "intentional self-harm" intent, not accidental or undetermined.
• This "initial encounter" code is only used for the first time the patient is seen for this specific toxic event.
