Poisoning by capillary-active drugs

This code signifies an adverse reaction or overdose due to drugs that affect capillary permeability and function. These substances can lead to conditions like shock, fluid shifts, and organ damage by altering the integrity of blood vessels. It encompasses both accidental and intentional poisonings.

Use this code when documentation clearly indicates a patient's illness or injury is a direct result of poisoning by capillary-active drugs. This includes medications such as certain vasodilators, vasoconstrictors, or other agents that directly impact capillary structure or function. Supporting documentation should specify the drug involved and the nature of the poisoning.

• Always code the specific drug responsible for the poisoning if known, using an E-code (E850-E869 for accidental, E950-E952 for suicide attempt, E962 for assault, E980-E982 for undetermined).
• Distinguish between poisoning (adverse effect due to overdose or wrong substance) and adverse effect in therapeutic use (E930-E949).
• Sequence this code as the primary diagnosis when the poisoning is the reason for the encounter, followed by codes for any resulting manifestations.
