Poisoning by coronary vasodilators, undetermined, sequela

This code signifies a long-term health problem or complication arising from an exposure to coronary vasodilators where the intent of the exposure (e.g., accidental, intentional self-harm, assault) cannot be determined. These sequelae are persistent effects that occur after the acute phase of the poisoning has resolved.

Use this code when documenting a chronic condition, disability, or other late effect directly attributable to a past poisoning by coronary vasodilators, and the original poisoning event was of undetermined intent. This applies to follow-up encounters for conditions like persistent cardiac arrhythmias, chronic hypotension, or organ damage that developed as a consequence of the poisoning.

• Always sequence this sequela code after the code for the specific manifestation of the sequela (e.g., chronic heart failure, renal failure).
• Ensure documentation clearly links the current condition to the past coronary vasodilator poisoning of undetermined intent.
• Do not use for acute poisoning events; this code is exclusively for residual effects.
