Poisoning by barbiturates, intentional self-harm, subs

This code signifies a patient presenting for follow-up care or treatment of complications arising from a deliberate overdose of barbiturates. The initial self-harm event has already occurred, and the current encounter addresses ongoing management or sequelae.

Apply this code for encounters such as medication adjustments, psychiatric evaluations, or treatment of organ damage (e.g., kidney failure, neurological deficits) directly resulting from a previous intentional barbiturate poisoning. It is appropriate when the patient is no longer in the acute phase of the overdose but requires continued medical attention.

• Always sequence this code after the primary diagnosis for the specific complication being treated.
• Ensure documentation clearly indicates "intentional self-harm" and that the encounter is "subsequent" to the initial event.
• Do not use for the initial acute poisoning event; refer to the appropriate initial encounter code for that scenario.
