Adverse effect of alpha-adrenoreceptor antagonists, sequela

This code signifies a long-term or residual condition resulting from a past adverse reaction to an alpha-adrenoreceptor antagonist medication. These medications are typically used to treat conditions like hypertension or benign prostatic hyperplasia. The adverse effect is no longer acute but has left a lasting impact on the patient's health.

Use this code when documenting a chronic or permanent sequela directly attributable to a previous adverse effect of an alpha-blocker. This would apply, for instance, if a patient developed persistent orthostatic hypotension or sexual dysfunction that began during alpha-blocker therapy and continues indefinitely after the medication has been discontinued or the acute phase has resolved.

• Always sequence this code after the code for the specific sequela (e.g., persistent orthostatic hypotension).
• Ensure documentation clearly links the current condition to a past adverse effect of an alpha-adrenoreceptor antagonist.
• Do not use for acute adverse effects; those would require an initial or subsequent encounter character.
