Poisoning by alpha-adrenocpt antagonists, accidental, subs

This code signifies an accidental overdose or adverse reaction to alpha-adrenoreceptor antagonist medications, such as prazosin or tamsulosin, during a follow-up visit. The patient is experiencing ongoing effects or complications from the initial poisoning event.

Apply this code when a patient presents for continued management, monitoring, or treatment of symptoms stemming from an unintentional poisoning by an alpha-blocker. This includes follow-up appointments for persistent hypotension, dizziness, or other side effects after the initial acute phase.

• Ensure documentation clearly states the poisoning was accidental and this is not the initial encounter.
• Always code the specific manifestation(s) of the poisoning first, if applicable.
• Verify the medication involved is indeed an alpha-adrenoreceptor antagonist.
