Poisoning by oth drug/meds/biol subst, self-harm, subs

This code signifies a patient presenting for follow-up care or treatment of complications arising from a deliberate act of self-poisoning using an unspecified drug, medication, or biological substance. The initial acute phase of the poisoning has passed, and the patient is now in a recovery or management stage.

This code is appropriate for subsequent visits related to the sequelae of a self-inflicted drug overdose, such as managing organ damage, psychiatric evaluation, or ongoing detoxification. It would be used when the patient is no longer in the immediate crisis of the poisoning but requires continued medical attention for the event.

• Ensure documentation clearly states "intentional self-harm" and that the encounter is not the initial treatment.
• Always code an underlying mental health condition (e.g., depression, anxiety) if documented as contributing to the self-harm.
• Verify that the specific substance is not known; if identified, a more specific T50 code should be used.
