Toxic effect of lead and its compounds, self-harm, subs

This code signifies a poisoning or adverse reaction resulting from lead or lead-containing compounds, where the patient intentionally ingested or exposed themselves to the substance with the intent to cause harm. The "subsequent encounter" indicates that this code is used for follow-up care, monitoring, or treatment of the toxic effects after the initial presentation.

Apply this code when documenting ongoing management of a patient who previously presented with lead poisoning due to a suicide attempt or self-inflicted harm. This includes outpatient visits for chelation therapy, neurological monitoring, or psychological evaluation related to the initial intentional exposure. It is appropriate for any encounter after the initial acute treatment.

• Always sequence this code after the primary diagnosis for the specific lead toxicity manifestation (e.g., lead encephalopathy).
• Ensure documentation clearly states "intentional self-harm" and that the encounter is not the initial presentation.
• Do not use for accidental exposures or therapeutic misadventures; those require different ICD-10-CM codes.
