Poisoning by beta-adrenocpt antagonists, self-harm, subs

This code signifies a poisoning event resulting from the deliberate self-administration of beta-blocker medications with the intent to cause harm. The patient is being seen for ongoing care, evaluation, or treatment related to this specific overdose after the initial acute phase.

Apply this code when a patient presents for follow-up appointments, medication adjustments, or management of complications stemming from a prior intentional beta-blocker overdose. This includes situations where the patient is stable but still requires monitoring or treatment for residual effects.

• Ensure documentation clearly states "intentional self-harm" and specifies the substance as a beta-adrenoreceptor antagonist.
• Confirm the encounter is a "subsequent encounter" for ongoing care, not the initial acute treatment.
• Always sequence this code after any codes for the specific clinical manifestations or complications of the poisoning.
