Toxic effect of formaldehyde, intentional self-harm, subs

This code signifies a toxic reaction to formaldehyde resulting from a deliberate act of self-harm. It indicates that the patient is receiving follow-up care for the sequelae of this poisoning, rather than the initial presentation. This could involve managing organ damage, respiratory issues, or other complications arising from the intentional exposure.

Apply this code when documenting subsequent encounters for patients who have intentionally poisoned themselves with formaldehyde. This includes visits for ongoing treatment, monitoring of long-term effects, or rehabilitation following the initial acute phase. It is appropriate for any follow-up care related to the self-inflicted formaldehyde toxicity.

• Ensure documentation clearly states "intentional self-harm" and that the encounter is not the initial presentation.
• Always code the specific manifestation of the toxic effect (e.g., respiratory failure, chemical burns) as a primary diagnosis if applicable.
• Do not use this code for accidental exposures or therapeutic misadventures.
