Toxic effect of dichloromethane, intentional self-harm, subs

This code describes a poisoning or adverse reaction resulting from the deliberate ingestion, inhalation, or exposure to dichloromethane, occurring during a follow-up visit for the initial self-harm event. The patient is receiving ongoing care for the effects of this toxic exposure, which was intended to cause self-injury.

Apply this code when documenting subsequent encounters for patients who intentionally harmed themselves using dichloromethane. This includes follow-up appointments for monitoring organ damage, managing persistent symptoms, or addressing complications arising from the initial toxic exposure. It is appropriate for any visit after the initial acute treatment phase.

• Ensure documentation clearly states the intent was self-harm and that this is a subsequent encounter.
• Always sequence this code after the primary diagnosis for the specific manifestation of the toxic effect (e.g., acute kidney injury, respiratory failure).
• Do not use for initial encounters or accidental exposures; different codes apply for those scenarios.
