Poisn by analeptics and opioid receptor antag, slf-hrm, subs

This code signifies a poisoning event resulting from the intentional self-harm use of analeptics or opioid receptor antagonists. The patient is receiving active treatment for the sequelae of this poisoning, which may include symptoms like seizures, respiratory depression, or cardiac arrhythmias, depending on the specific substance.

Apply this code for follow-up encounters when a patient is still actively being treated for the effects of a self-inflicted overdose of analeptic or opioid receptor antagonist medications. This includes scenarios where the patient is hospitalized for continued monitoring, detoxification, or management of complications arising from the initial poisoning.

• Always sequence this code after the primary diagnosis for the specific manifestation of the poisoning (e.g., acute respiratory failure).
• Ensure documentation clearly supports intentional self-harm and that the encounter is for active treatment of the poisoning's effects.
• Do not use this code for initial encounters; look for the "A" or "D" seventh character for subsequent encounters.
