Toxic effect of methanol, assault, subsequent encounter

This code signifies a toxic reaction to methanol poisoning that occurred as a result of an intentional act of harm by another person. It indicates that the patient is receiving follow-up care for the sequelae or complications of this initial methanol exposure.

Apply this code when documenting ongoing treatment, rehabilitation, or management of chronic effects stemming from a methanol poisoning that was inflicted by another individual. This includes situations where the patient is seen for persistent organ damage, neurological deficits, or other long-term health issues directly attributable to the assaultive methanol exposure.

• Ensure documentation clearly states the methanol exposure was due to an assault and that this is a subsequent visit for ongoing care.
• Always sequence this code after any codes for the specific manifestations or complications of the methanol toxicity.
• Do not use for initial encounters or for poisoning due to accidental or self-harm intent.
