Adverse effect of beta-adrenoreceptor antagonists, sequela

This code signifies a long-term or residual condition resulting from an adverse reaction to a beta-blocker medication. It indicates that the patient experienced an undesirable side effect from the drug, and this effect has now become a permanent or chronic health issue.

Apply this code when documenting a chronic or persistent health problem that is directly attributed to a past adverse effect of a beta-adrenoreceptor antagonist. This is appropriate for conditions like persistent bradycardia, chronic fatigue, or long-term bronchospasm that developed after beta-blocker use and are now considered sequelae.

• Always use in conjunction with a code describing the specific sequela (e.g., I49.5 for sick sinus syndrome).
• Ensure documentation clearly links the current chronic condition to a previous adverse drug event involving a beta-blocker.
• The "S" seventh character indicates a sequela, meaning the residual effect of an acute injury or illness.
