Toxic effect of petroleum products, self-harm, subs

This code signifies a patient presenting for follow-up care related to a previous act of intentional self-poisoning using petroleum products. The initial acute phase of treatment has concluded, and the patient is now receiving ongoing management for the effects of the toxic exposure or related mental health issues.

Use this code for subsequent encounters such as follow-up appointments with a gastroenterologist for persistent GI symptoms from the ingestion, a neurologist for ongoing neurological deficits, or a psychiatrist for mental health support following the self-harm attempt. It is appropriate when the patient is no longer in the acute phase of treatment but still requires medical attention directly related to the toxic effect.

• Ensure the encounter is for follow-up care, not the initial acute treatment.
• Verify the intent was self-harm, not accidental or assault.
• Confirm the substance involved was a petroleum product.
