Poisoning by ganglionic blocking drugs, undetermined, subs

This code signifies an adverse event resulting from exposure to ganglionic blocking agents, where the intent of the poisoning (e.g., accidental, intentional self-harm, assault) cannot be determined. The patient is receiving follow-up care for the sequelae of this poisoning after the initial treatment phase.

Apply this code when a patient presents for ongoing management or monitoring of complications directly related to an undetermined poisoning by ganglionic blocking drugs. This includes situations like follow-up appointments for organ damage, neurological deficits, or other lingering effects. It is used after the initial acute treatment has concluded.

• Requires a seventh character 'D' for subsequent encounter, indicating ongoing care.
• Only use when the intent of the poisoning is explicitly documented as "undetermined" or cannot be ascertained from the medical record.
• Always sequence this code after any codes for the specific manifestations or complications of the poisoning.
