Poisoning by other vasodilators

This code signifies an adverse reaction or overdose due to a vasodilator medication not otherwise specified. This includes both accidental and intentional poisonings resulting in toxic effects from drugs that widen blood vessels. The clinical presentation can range from hypotension and dizziness to more severe cardiovascular collapse.

Use this code when documentation clearly indicates a patient has experienced poisoning from a vasodilator that is not specifically listed elsewhere in the ICD-9-CM classification (e.g., nitrates, calcium channel blockers). This typically applies when the specific drug is identified as a vasodilator but lacks a more precise code, or when the documentation broadly states "other vasodilator." Supporting documentation should detail the substance involved and the resulting adverse effects.

• Always attempt to identify the specific vasodilator if possible; more specific codes exist for nitrates, calcium channel blockers, etc.
• Requires an E-code (E850-E869 for accidental, E950-E952 for suicide attempt, E980-E982 for undetermined intent) to indicate the external cause of poisoning.
• Do not use for adverse effects occurring during therapeutic use if the drug is correctly prescribed and administered; instead, consider codes from the 995.2x series.
