Poisoning by alpha-adrenoreceptor antagonists, assault, subs

This code signifies a poisoning event resulting from the intentional misuse or overdose of alpha-adrenoreceptor antagonist medications, such as prazosin or tamsulosin, with the intent to harm another person. The "subsequent encounter" indicates that the patient is receiving follow-up care for the sequelae of this poisoning after the initial treatment.

Apply this code when a patient presents for ongoing management, monitoring, or treatment of complications arising from an alpha-adrenoreceptor antagonist poisoning that was inflicted by another individual. This includes follow-up appointments for organ damage, cardiovascular issues, or other lingering effects after the acute phase of the poisoning has been addressed.

• Always use in conjunction with an external cause code (e.g., Y09.-) to fully describe the circumstances of the assault.
• Ensure documentation clearly specifies the intent of assault and that the encounter is for follow-up care, not the initial treatment.
• Distinguish carefully from accidental poisoning (T44.6X1-) or self-harm (T44.6X2-).
