Poisoning by peripheral vasodilators, undetermined, sequela

This code signifies the long-term effects or complications arising from an unconfirmed or unknown poisoning by a peripheral vasodilator. It indicates that the initial acute event of poisoning has resolved, but the patient continues to experience residual health problems directly attributable to that past exposure.

Apply this code when documenting chronic conditions, permanent disabilities, or persistent symptoms that are a direct consequence of a previous peripheral vasodilator poisoning where the intent (accidental, intentional self-harm, assault) could not be determined. This is appropriate for follow-up encounters after the acute phase of poisoning has passed.

• Always sequence this code after the code(s) for the specific sequela being treated.
• Ensure documentation clearly links the current condition to a past, undetermined peripheral vasodilator poisoning.
• Do not use for acute poisoning events; this code is exclusively for residual effects.
