Poisoning by predom alpha-adrenocpt agonists, undet, subs

This code signifies an adverse event resulting from exposure to a predominantly alpha-adrenoreceptor agonist, where the intent (e.g., accidental, intentional self-harm, assault) cannot be determined. The patient is being seen for follow-up care after the initial treatment of the poisoning.

Apply this code when a patient presents for ongoing management or monitoring of symptoms related to a previous poisoning by an alpha-agonist, and the circumstances surrounding the exposure remain unclear. This is appropriate for encounters after the acute phase of treatment has concluded.

• Requires a seventh character "D" for subsequent encounter, indicating follow-up care.
• Do not use for initial encounters or for sequelae (late effects) of the poisoning.
• Always sequence this code after any codes for the specific symptoms or conditions resulting from the poisoning.
