Poisoning by alpha-adrenocpt antag, accidental, sequela

This code indicates a patient is experiencing a long-term effect or complication from an accidental overdose or exposure to an alpha-adrenoreceptor antagonist. These medications are commonly used to treat hypertension or benign prostatic hyperplasia (BPH). The "sequela" designation signifies that the acute poisoning event has passed, but residual symptoms or conditions persist.

Apply this code when documentation clearly links a current condition or symptom to an accidental alpha-blocker poisoning that occurred in the past. Examples include persistent hypotension, syncope, or other organ damage directly attributable to the prior unintentional overdose. This code is used for follow-up care related to the lasting effects, not the initial acute poisoning.

• Always ensure the documentation specifies "accidental" and that the current condition is a direct sequela of the past poisoning.
• Remember to also code the specific manifestation(s) of the sequela, such as chronic hypotension (I95.1) or renal failure (N18.-), as primary or secondary diagnoses.
• The 7th character "S" indicates sequela and should only be used for complications or conditions arising as a direct result of the initial poisoning.
