Poisoning by opium, accidental (unintentional), subs encntr

This code signifies a patient presenting for follow-up care or treatment of complications arising from an accidental overdose or poisoning by opium. The initial acute phase of the poisoning has passed, and the patient is now receiving ongoing management for its effects.

Apply this code when documenting subsequent encounters for patients who previously experienced unintentional opium poisoning. This includes visits for monitoring organ damage, managing withdrawal symptoms, or addressing long-term sequelae of the overdose. It is appropriate for any encounter after the initial acute treatment.

• Ensure the "D" seventh character is used only for subsequent encounters, not initial treatment.
• Always code the specific manifestation of the poisoning (e.g., respiratory depression, anoxia) as a secondary diagnosis.
• Verify that the poisoning was indeed accidental and not intentional or undetermined, as different codes apply.
