Poisoning by unsp systemic antibiotic, self-harm, subs

This code signifies a patient presenting for follow-up care related to an intentional overdose of an unspecified systemic antibiotic. The initial event involved the patient deliberately taking an excessive amount of the medication with the intent to cause self-harm.

This code is appropriate for subsequent encounters, such as follow-up appointments, medication management, or psychotherapy sessions, after the initial acute poisoning event has been addressed. It indicates that the patient is being treated for the sequelae or ongoing management of the self-inflicted antibiotic poisoning.

• Ensure documentation clearly states "subsequent encounter" and "intentional self-harm."
• Only use this code when the specific antibiotic is not documented. If known, a more specific T36.x2XD code should be used.
• Always sequence this code after any codes for the specific medical conditions or complications resulting from the poisoning.
