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

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

Apply this code for patients admitted to the emergency department or hospital for acute methanol poisoning where the history clearly indicates a suicide attempt or intentional self-inflicted harm. This code is appropriate for the first encounter for this specific poisoning event.

• Always assign an additional code for the specific manifestation of methanol toxicity (e.g., blindness, metabolic acidosis).
• Do not use this code for accidental or undetermined intent; refer to other T51.1X codes for those scenarios.
• Ensure documentation supports the "initial encounter" designation, indicating the patient is receiving active treatment for the acute phase of the poisoning.
