Poisn by analeptics and opioid receptor antag, undet, subs

This code indicates a poisoning event involving analeptic medications (stimulants) or opioid receptor antagonists, where the intent of the poisoning (e.g., accidental, intentional self-harm, assault) cannot be determined. This specific code is used for encounters following the initial treatment of the poisoning, such as follow-up visits or ongoing management of complications.

Use this code for a patient presenting for follow-up care after an analeptic or opioid antagonist poisoning where the circumstances surrounding the poisoning remain unclear. This would include situations where the provider is unable to ascertain if the poisoning was accidental, intentional, or due to an assault. It's appropriate for subsequent visits for monitoring, medication adjustments, or addressing lingering effects.

• Requires a 7th character "D" for subsequent encounter, indicating ongoing care after the initial treatment.
• Only use when the intent of the poisoning is explicitly documented as "undetermined" or cannot be clarified by the provider.
• Always sequence this code after any codes for specific manifestations or complications of the poisoning.
