Toxic effect of ketones, intentional self-harm, sequela

This code describes the long-term or residual effects resulting from a past episode of poisoning due to ketones, where the exposure was intentionally self-inflicted. It indicates that the patient is now experiencing a chronic or permanent condition directly attributable to that previous toxic event.

Use this code when documenting a current condition that is a direct consequence of a prior, resolved toxic exposure to ketones, which was determined to be an intentional self-harm attempt. This applies to follow-up encounters where the acute poisoning has passed, but lasting sequelae remain.

• Always sequence this code after the code(s) for the specific sequela(e) being treated.
• Do not use this code for acute poisoning or when the patient is still experiencing the active toxic effects.
• Ensure documentation clearly links the current condition to the past intentional self-harm by ketones.
