Toxic effect of oth metals, intentional self-harm, subs

This code signifies a poisoning or adverse reaction resulting from the deliberate ingestion or exposure to a metallic substance, other than those specifically classified elsewhere (e.g., lead, mercury, arsenic). The intent of the exposure is self-harm, and the patient is presenting for follow-up care after the initial treatment of the toxic effect.

Apply this code when a patient is seen for ongoing management, monitoring, or complications related to a prior intentional self-poisoning involving a metal not otherwise specified. This includes situations where the patient is returning for repeat lab work, specialist consultations, or treatment of lingering symptoms from the initial toxic exposure.

• Ensure documentation clearly states the intent was self-harm and the encounter is subsequent.
• Always sequence this code after the primary diagnosis for the specific toxic effect, if applicable.
• Verify the specific metal involved is not covered by a more precise T56 subcategory.
