Poisoning by beta-adrenoreceptor antagonists, assault, subs

This code signifies a patient presenting with adverse effects resulting from an intentional overdose or malicious administration of a beta-blocker medication. The "subsequent encounter" indicates that this is not the initial visit for this specific poisoning event, but rather a follow-up for ongoing treatment, monitoring, or complications.

This code is appropriate for documenting follow-up care for a patient who was previously diagnosed with beta-blocker poisoning due to an assault. This includes scenarios such as monitoring cardiac function, managing persistent bradycardia or hypotension, or addressing other organ system damage that occurred as a result of the initial poisoning.

• Ensure documentation clearly specifies "assault" as the intent, not accidental or self-harm.
• Verify that this is a subsequent encounter; use the "A" or "S" seventh character for initial or sequela encounters, respectively.
• Always code the specific beta-blocker if known, using additional codes from categories T44.x.
