Poisoning by ganglionic blocking drugs, assault, subs encntr

This code signifies a patient presenting with adverse effects from ganglionic blocking medications, specifically when the poisoning was intentionally inflicted by another person. The "subsequent encounter" indicates that the patient is receiving follow-up care for the poisoning after the initial treatment.

This code is appropriate for documenting ongoing management of a patient who was poisoned by ganglionic blocking drugs due to an assault. This includes follow-up appointments, monitoring for long-term effects, or treatment of residual symptoms after the initial acute phase has passed.

• Always assign an additional code for the specific ganglionic blocking drug involved, if known.
• Do not use this code for initial treatment of the poisoning; a code with an "A" (initial encounter) seventh character would be appropriate then.
• Consider external cause codes (V00-Y99) to further describe the circumstances of the assault.
