Toxic effect of formaldehyde, intentional self-harm, init

This code signifies a patient presenting with adverse health effects resulting from the deliberate ingestion, inhalation, or other exposure to formaldehyde, with the intent to cause self-harm. The "initial encounter" indicates that this is the first time the patient is receiving active treatment for this specific poisoning event.

Apply this code when documenting a patient admitted to the emergency department or hospital after a suicide attempt involving formaldehyde. This would include cases where the patient intentionally drank formaldehyde-containing solutions or intentionally inhaled formaldehyde fumes to harm themselves.

• Always sequence this code first if it is the primary reason for the encounter.
• Requires an additional code for the specific manifestation of the toxic effect (e.g., respiratory failure, chemical burns).
• Do not use for accidental or unintentional formaldehyde exposure; refer to codes in the T59.2X1- series for such cases.
